Abstract
Description
Technical Field
[0001] The present disclosure generally relates to gaskets, and more specifically, to gaskets used for depositing material layers onto workpieces.
Background Art
[0002] Gaskets are commonly used to fill the space between two or more surfaces and are generally intended to prevent leakage when compressed. Gaskets may be made from rubber, metal, or polymer materials and can have various sizes and shapes. In semiconductor device manufacturing, gaskets can generally be used to prevent leakage from a container holding a chemical substance to a tool into which the chemical substance is introduced. In semiconductor device manufacturing, the gasket may generally be in the shape of an O-ring and can be manufactured from materials suitable for various chemicals, temperatures, and pressures. O-rings are commonly used to seal connections between two surfaces, such as between a chemical container and a supply conduit, for introducing chemicals into semiconductor device manufacturing tools.

[0029] While certain specific embodiments and models are disclosed below, it will be understood by those skilled in the art that the scope of the invention extends beyond the specifically disclosed embodiments and / or uses of the invention, as well as their obvious modifications and equivalents. Therefore, the scope of the invention disclosed is not limited by the specific disclosed embodiments described below.
[0030] Referring to Figure 1, a semiconductor processing system 200 including an injector device 100 is shown. The semiconductor processing system 200 includes a precursor source 202, a chamber arrangement 204 including the injector device 100, an exhaust source 206, and a controller 208. The precursor source 202 is fluidly connected to the chamber arrangement 204 by a precursor supply conduit 210 and contains a material layer precursor 10, and is configured to transmit the flow of the material layer precursor 10 to the chamber arrangement 204. The chamber arrangement 204 includes a substrate support 230 (shown in Figure 2) and is connected to the exhaust source 206 by an exhaust conduit 214 and is configured to expose the substrate 2 (shown in Figure 2) placed on the substrate support 230 to the material layer precursor 10 under selected environmental conditions (e.g., pressure and / or temperature) for depositing a material layer 4 onto the substrate 2. The exhaust source 206 communicates with the external environment 12 outside the semiconductor processing system 200 and is configured to transmit the flow of residual precursors and / or reaction products 14 emitted by the chamber configuration 204 using abatement devices such as a vacuum pump and a scrubber during the deposition of the material layer 4 (shown in Figure 2) onto the substrate 2. The controller 208 is operably connected to one or more elements of the semiconductor processing system 200, such as the precursor source 202, to control the flow of material layer precursors 10 through the injector device 100 during the deposition of the material layer 4 onto the substrate 2, and may be connected to it by a wired or wireless link 216.
[0031] In certain embodiments, the precursor source 202 may be configured to transport one or more silicon-containing material layer precursors within the material layer precursor 10 that are transported to the chamber configuration 204. Examples of suitable material layer precursors include non-chlorinated silicon-containing material layer precursors silane (SiH4) or disilane (Si2H6) and / or halogenated material layer precursors, such as chlorinated silicon-containing material layer precursors (e.g., dichlorosilane (H2SiCl2) or trichlorosilane (HCl3Si)). Other material layer precursors may include metal precursors, organometallic precursors, and halides. In some embodiments, the material layer precursor may include one or more elements selected from hydrogen, alkali metals, alkaline earth metals, transition metals, lanthanides, post-transition metals, group 13 elements, group 14 elements, chalcogens, nictogens, halogens, and noble gases.
[0032] According to a particular embodiment, the precursor source 202 may be configured to transfer the dopant-containing material layer precursor and / or alloy component in the material layer precursor 10 to the chamber arrangement 204. Examples of suitable dopant-containing material layer precursors include n-type dopant-containing material layer precursors such as compounds containing phosphorus (P) or arsenic (As), and p-type dopant-containing material layer precursors such as compounds containing boron (B). Examples of suitable alloy components include germanium-containing compounds such as germanium (GeH4) as non-limiting examples.
[0033] The precursor source 202 is intended to be configured to deliver an etchant to the chamber configuration 204, which can either flow together with the material layer precursor 10 or be provided as a separate flow to the chamber configuration 204. Examples of suitable etchants include halogen-containing compounds such as hydrochloric acid (HCl) and chlorine (Cl2) gas, as well as fluorine-containing compounds such as hydrofluoric acid (HF). The precursor source 202 is also intended to be configured to deliver a diluent or carrier fluid (e.g., a gas) to the chamber configuration 204. For example, the precursor source 202 may be configured to deliver one or more of the following: hydrogen (H2) gas, nitrogen (N2) gas, a noble gas, or a mixture containing one or more of the aforementioned gases. The carrier or diluent fluid may be delivered to the chamber configuration 204 together with the material layer precursor 10 or separately, such as in a purge fluid flow.
[0034] Where used in this disclosure, the term “substrate” may refer to one or more arbitrary substrate materials, such as one or more arbitrary substrate materials, which may be modified or on which devices, circuits, or films may be formed. “Substrate” may be continuous or discontinuous, rigid or flexible, solid or porous, or a combination thereof. The substrate may be in any form, such as powder, plate, or workpiece. The substrate may be made from semiconductor materials, including, for example, silicon (Si), silicon germanium (SiGe), silicon oxide (SiO2), gallium arsenide (GaAs), gallium nitride (GaN), and silicon carbide (SiC). For example, a substrate in powder form may have applications in pharmaceutical manufacturing. Porous substrates may include polymers. Examples of workpieces may include medical devices (e.g., stents and syringes), jewelry, tooling devices, cutlery, fasteners (e.g., screws, nails, or bolts), components for battery manufacturing (e.g., anodes, cathodes, or separators), or components for photovoltaic cells. Continuous substrates may extend beyond the boundaries of the process chamber where the deposition process takes place. In some processes, the continuous substrate may move through the process chamber, thereby allowing the process to continue until it reaches the end of the substrate. Continuous substrates may be supplied from a continuous substrate supply system to enable the manufacture and production of continuous substrates in any suitable form. Non-limiting examples of continuous substrates may include sheets, nonwoven films, rolls, foils, webs, flexible materials, and bundles of continuous filaments or fibers (e.g., ceramic fibers or polymer fibers). Continuous substrates may also include carriers or sheets on which discontinuous substrates are placed.
[0035] Referring to Figure 2, a semiconductor processing system 200 including an injector device 100 according to one embodiment of the present disclosure is shown. In the illustrated embodiment, the chamber arrangement 204 has a plurality of substrate architectures 218 and includes a chamber body 220, an array of heating elements 222, and one or more temperature sensors 224. One or more temperature sensors 224 may be positioned within the chamber body 220 to monitor the temperature of the chamber body 220 and / or the plurality of substrates 2 of the plurality of substrate architectures 218 and communicate with a controller 208. In certain embodiments, one or more temperature sensors 224 may be thermocouples, pyrometers, or a combination thereof. The array of heating elements 222 may surround the chamber body 220 and may be used to heat the plurality of substrates 2 to a predetermined temperature for the deposition of a material layer 4. The array of heating elements 222 may communicate with one or more temperature sensors 224 by the controller 208, and the controller 208 may adjust the power (not shown) supplied to the array of heating elements 222 based on signals transmitted from one or more temperature sensors 224. In certain embodiments, the heating element array 222 may include a plurality of filament-type heater elements, such as linear lamps. According to certain embodiments, the heating element array 222 may include a plurality of bulb-type heater elements. According to certain embodiments, the heating element array 222 may include a combination of both filament-type and bulb-type heater elements, within the scope of this disclosure.
[0036] The chamber body 220 has a hollow interior 226 and may generally be bell jar shaped. The chamber body 220 has a supply opening 236 and an exhaust opening 238. The supply opening 236 fluidly connects the chamber body 220 to a precursor supply conduit 210, while the exhaust opening 238 fluidly connects the chamber body 220 to an exhaust conduit 214. In this regard, the precursor source 202 is fluidly connected to the exhaust source 206 by the chamber body 220. The chamber body 220 is intended to be formed from a ceramic material 228. In certain embodiments, the ceramic material 228 may be a transparent material, such as quartz or sapphire, which is transparent to electromagnetic radiation in the infrared wavelength band.
[0037] The hollow interior 226 of the chamber body 220 may further include an injector device 100, a substrate support 230, a pedestal 232, a movable door 246, and an injector 234. The injector device 100 may be configured to support the injector 234 within the hollow interior 226 of the chamber body 220, and in this respect may include an injector holder 102, a reactor flange 104, a connecting member 106, and a connector body 108. The injector 234 is connected to the injector device 100 at its first end. The injector 234 fluidly communicates a material layer precursor 10 into the hollow interior 226 of the chamber body 220 in order to deposit a material layer 4 onto a plurality of substrates 2 from its second end. In certain embodiments, the injector 234 may be formed from a heat-resistant material 240. The injector 234 is intended to be formed from a ceramic material. In certain embodiments, the injector 234 may be formed from silicon carbide (SiC), silicon (Si), or quartz, as non-limiting examples. A movable door 246 supports the pedestal 232 and the substrate support 230 within the hollow interior 226 of the chamber body 220. The movable door 246 allows the substrate support 230 to be inserted into the hollow interior 226 of the chamber body 220 from the outside of the chamber body 220, or removed from the hollow interior 226 of the chamber body 220 to the outside of the chamber body 220. The substrate support 230 is supported within the hollow interior 226 of the chamber body 220 by the pedestal 232 and may be configured to support a plurality of substrates 2. The substrate support 230 may be configured to support, for example, 100 substrates, 120 substrates, 150 substrates, 170 substrates, or more than 170 substrates. In certain embodiments, the substrate support 230 may be formed from a heat-resistant material 244. The substrate support 230 is intended to be formed from a ceramic material. In certain embodiments, the substrate support 230 may be formed from silicon carbide (SiC), silicon (Si), or quartz, as non-limiting examples.
[0038] The pedestal 232 supports the substrate support 230 within the hollow interior 226 of the chamber body 220. According to certain embodiments, the workpiece may be supported solely by the pedestal 232 within the hollow interior 226 of the chamber body 220, and this remains within the scope of the disclosure. In these embodiments, the workpiece may not be the substrate 2, but may be a component for aerospace, automotive, or other applications that can benefit from the material layer deposited on the workpiece. As will be understood by those skilled in the art, by placing the workpiece directly on the pedestal 232, it becomes possible for larger workpieces to accommodate the material layer deposited on the workpiece. According to certain embodiments, the workpiece may be supported by the pedestal 232 and an alternative support mechanism within the hollow interior 226 of the chamber body 220, and may also be a workpiece for aerospace, automotive, or other applications that can benefit from the material layer deposited on the workpiece. In certain embodiments, the pedestal 232 may be formed from a heat-resistant material 242. The pedestal 232 is intended to be formed from a ceramic material. In certain embodiments, the pedestal 232 may be formed from silicon carbide (SiC), silicon (Si), or quartz, as non-limiting examples.

The controller 208 may include a processor 248, a device interface 250, a user interface 252, a plurality of program modules 254, and a memory 256. The device interface 250 may connect the controller 208 to the precursor source 202 via a wired or wireless link 216 and / or other elements of the semiconductor processing system 200, and is connected to the processor 248. The processor 248 is connected to the device interface 250 and operably connected to the user interface 252, through which it receives user input and / or provides user output, and is arranged to communicate with the memory 256. The memory 256 includes a non-temporary machine-readable medium having a plurality of program modules 254 recorded thereon, which, when read by the processor 248, contain instructions that cause the processor 248 to perform specific operations. Among these operations is the operation of the material layer deposition method 300 (shown in Figure 7), which is described below. Although described herein as having a specific architecture, the controller 208 may have a different architecture (e.g., a distributed computing architecture) in other embodiments of the Disclosure, and it is understood that this will remain within the scope of the Disclosure. For example, the controller 208 may be configured to control the volume of material layer precursor 10 flowing from the precursor source 202 into the injector device 100. The controller 208 may be configured to adjust the heating element array 222 in response to signals received from one or more temperature sensors 224 communicating with the controller 208. The controller 208 may be configured to open and close a movable door 246 of the chamber body 220. The controller 208 may be configured to remove excess precursor from the hollow interior 226 of the chamber body 220 to the external environment 12 by an exhaust source 206.
[0040] Referring to Figures 3 to 6, an injector device 100 according to one embodiment of the present disclosure is shown.

The first injector collar end 112 of the injector collar 110 slidably receives the injector 234 (shown in Figure 2). The injector rim 116 is connected to the second injector collar end 114 of the injector collar 110 and defines an injection opening 120. The injector rim 116 further defines a plurality of longitudinal openings 136 radially outward from the injection opening 120. The injector projection 118 extends from the injector rim 116 and surrounds the periphery of the injection opening 120. In the illustrated embodiment, the injector projection 118 is radially inward of the longitudinal opening 136. In certain embodiments, the injector projection 118 may be radially outward of the longitudinal opening 136. In the illustrated embodiment, the injector projection 118 forms a single acute angle. In certain embodiments, the injector projection 118 may form an obtuse angle, a 90-degree angle with respect to the connecting member 106, be rounded, or consist of one or more of the aforementioned geometric shapes, within the scope of this disclosure. As will be understood by those skilled in the art, these geometric shapes provide flexibility based on the environmental conditions selected for depositing the material layer 4 onto the substrate 2. In certain embodiments, the injector holder 102 may be formed from a heat-resistant material. It is intended that the injector holder 102 may be formed from a ceramic material 142. In certain embodiments, the injector holder 102 may be formed from silicon carbide (SiC), silicon (Si), or quartz, as non-limiting examples.
[0042] The reactor flange 104 may include a tubular member 122 having a first tubular member end 124 and a second tubular member end 126, a reactor rim 128, and a reactor projection 130. The reactor rim 128 is connected to the first tubular member end 124 of the tubular member 122 and defines the reactor opening 132. The reactor rim 128 further defines a plurality of longitudinal recesses 138 radially outward from the reactor opening 132. The second tubular member end 126 of the tubular member 122 is connected to a supply conduit 210 (shown in Figure 2). Similar to the injector holder 102, the reactor flange 104 may be formed from a heat-resistant material. In certain embodiments, the reactor flange 104 may be formed from a ceramic material 144. In non-limiting examples, the reactor flange 104 may be formed from silicon carbide (SiC), silicon (Si), or quartz. The reactor projection 130 is similar to the injector projection 118 and extends from the reactor rim 128. The reactor projection 130 surrounds the reactor opening 132 and is radially inward of the multiple longitudinal recesses 138. In certain embodiments, the reactor projection 130 is radially outward of the multiple longitudinal recesses 138.
[0043] As will be understood by those skilled in the art, in some embodiments, one or more of the injector holder 102, reactor flange 104, and injector 234 may be formed from the same material. In some embodiments, two or more of the injector holder 102, reactor flange 104, and injector 234 may be formed from the same material. In some embodiments, all of the injector holder 102, reactor flange 104, and injector 234 may be formed from the same material. In some embodiments, at least one of the injector holder 102, reactor flange 104, and injector 234 contains silicon.
[0044] In the illustrated embodiment, the reactor projection 130 is closer to the connector body 108 than the injector projection 118. As will be understood by those skilled in the art, the reactor projection 130 may be at the same distance from the connector body 108 as the injector projection 118, or it may be further away. Although shown and described herein as having the same geometric shape, both the injector projection 118 and the reactor projection 130 may have different geometric shapes, and it will be understood that this remains within the scope of the disclosure. In certain embodiments, either the injector projection 118 or the reactor projection 130 may be absent, and this remains within the scope of the disclosure. In the illustrated embodiment, the injector projection 118 and the reactor projection 130 are not vertically aligned along the vertical dashed line 140. In certain embodiments, both the injector projection 118 or the reactor projection 130, either one, part of either, or a combination thereof may be aligned along the vertical dashed line 140, and this remains within the scope of the disclosure. In certain embodiments where the geometric shapes of the injector protrusion 118 and the reactor protrusion 130 differ, all or some of the different geometric shapes may be aligned along the vertical dashed line 140, or none may be aligned, and this remains within the scope of the disclosure.
[0045] The connecting member 106 is positioned between the injector holder 102 and the reactor flange 104 and defines the precursor opening 134. Together with the injector holder 102 and the reactor flange 104, the connecting member 106 provides a sealing mechanism for the flow of material layer precursor 10 from the precursor source 202 to the injector 234 after the material layer precursor 10 has flowed through the supply opening 236 and the precursor supply conduit 210 (shown in Figure 2). The sealing mechanism is further supported by the injector projection 118 and the reactor projection 130. The connecting member 106 is intended to be formed from a malleable material 146. The malleable material 146 may be a material that can be deformed without fracturing while under compressive force. The connecting member 106 may, in non-limiting examples, be formed from a soft metallic material such as nickel (Ni), palladium (Pd), platinum (Pt), titanium (Ti), and cadmium (Cd), other transition metal materials, or metal alloys.
[0046] The connector body 108 may be one of a plurality of connector bodies. The connector body 108 is slidably received by a plurality of longitudinal recesses 138 through a plurality of longitudinal openings 136. The connector body 108 may be mechanically coupled to the injector holder 102, the reactor flange 104, and the connecting member 106 such that the injector projection 118 and the reactor projection 130 can cause deformation of the connecting member 106 at the projections. As those skilled in the art will understand, in addition to deformation of the connecting member 106 at the projections, the connecting member 106 may also be subjected to compression by the injector holder 102 and the reactor flange 104 when the connector body 108 is further placed within the injector rim 116. This compression may further increase the sealing properties of the connecting member 106.
[0047] In the illustrated embodiment, a plurality of axial openings 136 are defined by the injector rim 116, while a plurality of axial recesses 138 are defined by the reactor rim 128. In certain embodiments, the plurality of axial openings 136 may be defined by the reactor rim 128, and the plurality of axial recesses 138 may be defined by the injector rim 116, still within the scope of the disclosure. The axial openings 136 may or may not have threads to slidably receive the connector body 108, and the axial recesses 138 may have threads. Although the connector body 108 is shown and described herein as similar to a “bolt”, the connector body 108 may include other techniques for connecting the injector holder 102, the reactor flange 104, and the connecting member 106. The connector body 108 is intended to be formed from a heat-resistant material 148. The connector body 108 is intended to be formed from a metallic material. The connector body 108 may, in non-limiting examples, be formed from silicon (Si), quartz, silicon carbide (SiC), aluminum oxide (Al2O3), stainless steel, or a metal alloy.
[0048] In the illustrated embodiment, the injector holder 102, reactor flange 104, and connecting member 106 connect the precursor source 202 to the hollow interior 226 of the chamber body 220 via the precursor supply conduit 210, supply opening 236, precursor opening 134, and injector 234 (shown in Figure 2) so that the material layer precursor 10 can be deposited on the substrate 2 to form the material layer 4. As will be understood by those skilled in the art, the precursor opening 134, reactor opening 132, and injection opening 120 may be aligned so that the material layer precursor 10 flows through the injector device 100 with minimal turbulence. Reducing the flow turbulence of the material layer precursor 10 can improve the uniformity of the material layer 4 formed on the substrate 2.
[0049] As shown in Figure 4, an exploded cross-sectional view of the injector device 100 is shown in which the connector body 108 is slidably received by a plurality of longitudinal recesses 138 through a plurality of longitudinal openings 136, and the connector body 108 is placed within the injector rim 116. In a particular embodiment, the plurality of longitudinal openings 136 may be defined by the reactor rim 128, and the plurality of longitudinal recesses 138 may be defined by the injector rim 116, and the connector body 108 is placed within the reactor rim 128 of the reactor flange 104.
[0050] As shown in Figure 5, a partial cross-sectional view of the injector device 100 is provided. In the illustrated embodiment, when the injector holder 102, coupling member 106, and reactor flange 104 are connected by the connector body 108, the injector projection 118 and reactor projection 130 may cause deformation of the connecting member 106 along the vertical dashed line 140. Although both the injector projection 118 and reactor projection 130 are shown and described herein as being aligned along the vertical dashed line 140, one or both of the injector projection 118 or reactor projection 130 may not be aligned along the vertical dashed line 140, and this remains within the scope of the disclosure. As will be understood by those skilled in the art, the injector projection 118 and reactor projection 130 may be aligned along the vertical dashed line 140 in the transverse view but not in the longitudinal view, and vice versa, and this remains within the scope of the disclosure. In certain embodiments, both the injector projection 118 and the reactor projection 130 may be aligned along the vertical dashed line 140 in both the lateral and longitudinal views, and this remains within the scope of the disclosure.
[0051] As shown in Figure 6, a partially cross-sectional exploded view of the injector device 100 is provided. In the illustrated embodiment, the injector projection 118 and the reactor projection 130 are shown to extend from the injector rim 116 and the reactor rim 128, respectively. In addition, the connecting member 106 is shown not to be pre-molded or pre-formed to receive either the injector projection 118 or the reactor projection 130. As will be understood by those skilled in the art, the connecting member 106 can take the geometric shape of the injector projection 118 and / or the reactor projection 130 when the connector body 108 connects the injector holder 102, the reactor flange 104, and the connecting member 106. When the injector holder 102, the reactor flange 104, and the connecting member 106 are connected together by the connector body 108, the connecting member 106 is compressed. The injector protrusion 118, together with the reactor protrusion 130, causes deformation of the connecting member 106, resulting in improved sealing of the injector device 100. The compression and deformation of the connecting member 106 may be partially attributable to the material selected for the connecting member 106, for example, the malleable material 146.
[0052] Referring to Figure 7, a material layer deposition method 300 is shown. The material layer deposition method 300 may also include a connector body 108 mechanically connecting an injector holder to a reactor flange via a connecting member between them, for example, the connector body being slidably received through a plurality of axial openings 136 and received by a plurality of axial recesses 138 (shown in Figure 3). The material layer deposition method 300 may also include placing a workpiece in a chamber body (e.g., a substrate 2 in a chamber body 220 (shown in Figure 2)), as shown in box 302. The material layer deposition method 300 may further include heating the workpiece in the chamber body to a predetermined material layer deposition temperature, for example, by applying power to an array of heating elements 222 to generate electromagnetic radiation in the infrared wavelength band (shown in Figure 2), as shown in box 304. The material layer deposition method 300 may further include, as shown in boxes 306 and 308, exposing a workpiece to a material layer precursor in the chamber body, for example, exposing a substrate 2 (shown in Figure 2) to a material layer precursor 10 (shown in Figure 2), and depositing a material layer on the workpiece using the material layer precursor, for example, depositing a material layer 4 (shown in Figure 2) using the material layer precursor 10.
[0053] As shown by box 302, placing a workpiece into the chamber body 302 may include opening a movable door below the pedestal, for example, a movable door 246 (shown in Figure 2) supporting the pedestal 232, and inserting the substrate support into the chamber body with one or more workpieces placed within the substrate support (for example, a substrate support 230 (shown in Figure 2) having multiple substrates 2). The movable door may then be closed. Placing a workpiece 302 may include opening a movable door below the pedestal and inserting the workpiece directly into the chamber body. Placing a workpiece into the chamber body 302 may be achieved using a controller, for example, using instructions recorded in one or more of a plurality of program modules 254 on memory 256, to open the movable door, place one or more workpieces within the substrate support, raise the substrate support into the chamber body, and close the movable door.
[0054] Heating the workpiece to a predetermined material layer deposition temperature 304 may include radiating heat into the chamber body, as shown by box 304. Radiative heating can be achieved by generating electromagnetic radiation in the infrared wavelength band from heater elements supported outside the chamber body, which is conducted through the ceramic material forming the chamber body, for example, using an array of heating elements 222 (shown in Figure 2) and conducted through the ceramic material 228 (shown in Figure 2) forming the chamber body 220. Heating the workpiece 304 may also include detecting the temperature of the workpiece using a temperature sensor array and transmitting a signal to a controller, for example, one or more temperature sensors 224 communicating with a controller 208 via a wired or wireless link 216 to transmit the temperature of the substrate 2 (shown in Figure 2). Heating the workpiece inside the chamber body 304 can be achieved by using a controller, for example, by using instructions recorded in one or more of a plurality of program modules 254 stored in the memory 256 of the controller 208 to control the array of heating elements, receive signals from temperature sensors, or adjust the output provided to the heater element array based on signals received from temperature sensors.
[0055] Exposure of the workpiece to a material layer precursor 306 may include exposing the workpiece to a silicon-containing material layer precursor, such as a non-chlorinated silicon-containing material layer precursor such as silane (SiH4) or disilane (Si2H6), and / or a halogenated, such as chlorinated silicon-containing material layer precursor such as dichlorosilane (H2SiCl2) or trichlorosilane (HCl3Si). Other material layer precursors include metal precursors, organometallic precursors, and halides. In some embodiments, the material layer precursor may include one or more elements selected from hydrogen, alkali metals, alkaline earth metals, transition metals, lanthanides, post-transition metals, group 13 elements, group 14 elements, chalcogens, nictogens, halogens, and noble gases. Exposure of a workpiece to a material layer precursor 306 may include exposing the workpiece to a dopant-containing material layer precursor or an alloy-containing material layer precursor, such as an n-type dopant-containing material layer precursor containing arsenic (As) or phosphorus (P), or a p-type dopant-containing material layer precursor containing boron (B), as well as a germanium-containing material layer precursor such as germanium (GeH4). Exposure of a workpiece to a material layer precursor 306 may include exposing the substrate to an etchant, such as a chlorinated etchant like hydrogen chloride (HCl) gas or chlorine (Cl2) gas, or a fluorinated composition like hydrofluoric acid (HF). Exposure of a workpiece to a material layer precursor 306 may include co-circulating a carrier or diluent fluid with a material layer precursor such as hydrogen (H2) gas or nitrogen (N2) gas. Exposure of a workpiece to a material layer precursor 306 may include exposing the workpiece to a mixture containing a silicon-containing material layer precursor, a dopant-containing material layer precursor, an etchant, and a carrier or diluent. It is also intended that exposure of a workpiece to a material layer precursor 306 may be achieved by using a controller to control the flow of the material layer precursor 10 from the precursor source 202 into the injector device 100 and then into the injector 234, for example, using instructions recorded in one or more of the multiple program modules 254 recorded in memory 256.
[0056] Depositing a material layer on a workpiece 308 may include depositing a substantially uniform material layer on the workpiece (for example, a material layer 4 deposited on a substrate 2 (shown in Figure 2)). Depositing a material layer 308 may include depositing a proprietary silicon material layer or a silicon-containing material layer such as silicon germanium, as well as a doped silicon-containing material layer. Depositing a material layer 308 may include depositing a non-chlorinated silicon-containing material layer precursor such as silane (SiH4) or disilane (Si2H6), and / or a halogenated, chlorinated silicon-containing material layer precursor such as dichlorosilane (H2SiCl2) or trichlorosilane (HCl3Si). Depositing a material layer 308 may include depositing other material layer precursors, including metal precursors, organometallic precursors, and halides. Depositing a material layer 308 may include depositing one or more elements selected from hydrogen, alkali metals, alkaline earth metals, transition metals, lanthanides, post-transition metals, group 13 elements, group 14 elements, chalcogens, nictogens, halogens, and noble gases. Depositing a material layer 308 may include depositing dopant-containing material layer precursors or alloy-containing material layer precursors, such as n-type dopant-containing material layer precursors containing arsenic (As) or phosphorus (P), or p-type dopant-containing material layer precursors containing boron (B), as well as germanium-containing material layer precursors such as germanium (GeH4). It is intended that the deposition of the material layer can be controlled by using a controller to control the flow of the material layer precursor 10 from the precursor source 202 into the injector device 100 and then into the injector 234, for example, by using instructions recorded in one or more of the multiple program modules 254 recorded in memory 256.
