Description

Technical Field

[0001] This invention relates to the field of semiconductor processing equipment technology, and specifically to a hot plate module core assembly, a cover assembly, a hot plate module, and semiconductor processing equipment. Background Technology

[0002] With the continuous development of semiconductor technology, the requirements for precision control of production equipment are increasing. To adapt to the ever-advancing process nodes, the heat treatment process in semiconductor wet process equipment is gradually transitioning towards higher uniformity and higher stability. Hot plate modules are currently the main components in the industry for addressing the process requirements such as substrate heating and baking.

[0003] Semiconductor substrates come in a variety of sizes, and their process windows are often extremely demanding. The airflow environment inside the hot plate module and around the substrate is crucial for ensuring the uniformity of the process. To achieve more uniform heating or to form an isolation gas curtain, specific process gases need to be delivered to the substrate from a support plate underneath.

[0004] The delivery and processing of process gases can be further divided into several sub-schemes. Existing gas supply methods involve creating several separate air inlets on a support plate, from which the process gas is directly ejected upwards. Generally, to ensure adequate airflow coverage, the number and distribution of these air inlets are subject to stringent design requirements. If the airflow velocity and pressure differences on the substrate surface are too large during the gas supply process, it will not only lead to uneven temperature distribution on the substrate surface but may also affect the consistency of chemical reaction rates. Furthermore, it may cause more serious problems such as particulate contamination due to localized airflow disturbances. Summary of the Invention

[0013] The present invention provides a cover assembly for a hot plate module, including a shell and a flow equalization plate. The shell defines an internal cavity and has an exhaust port for connecting an exhaust pipe. The flow equalization plate is disposed in the internal cavity of the shell, below the exhaust port, dividing the internal cavity into an upper exhaust chamber and a lower processing chamber. The flow equalization plate has a plurality of through guide holes for connecting the processing chamber and the exhaust chamber. The flow equalization plate has a solid blocking area that covers the area where the exhaust port is projected along the normal direction of the flow equalization plate. The guide holes are distributed outside the solid blocking area to force airflow from the processing chamber through the guide holes to the exhaust chamber and converge to the exhaust port within the exhaust chamber.

[0014] Preferably, the aperture or distribution density of the flow guide holes varies along the direction away from the solid blocking area, wherein the flow guide holes near the edge of the processing chamber have a larger aperture or higher distribution density than the flow guide holes near the center; or, the exhaust port is formed above the geometric center of the flow equalization plate.

The module body is configured to be pushed into a compartment of a semiconductor processing device along the insertion direction. The support plate is disposed within the module body. The plate cover is disposed above the support plate and has an exhaust port. The exhaust airflow path is disposed on the plate cover, with one end connected to the exhaust port of the plate cover and the other end extending to the back of the module body to form a docking air vent.

Detailed Implementation

[0032] The present patent type will be described in detail below with reference to the accompanying drawings and specific embodiments. In this specification, the dimensions in the drawings do not represent actual size ratios. The drawings are only used to illustrate the relative positional and connection relationships between the components. Components with the same name or the same reference numerals represent similar or identical structures and are limited to illustrative purposes.

[0033] Figure 1 This is a schematic diagram of a semiconductor processing apparatus 1 according to an embodiment of the present invention. Typically, a substrate requiring heat treatment, such as a wafer, is placed on a hot plate module 10 for heating and baking processes. The hot plate module 10 is commonly a pluggable module integrated within a rack 2, with internal structures for supporting and processing the substrate. In a large semiconductor processing apparatus 1, the hot plate module 10 can be replaced and maintained as an independent unit. Although the term "substrate" is used to refer to the workpiece to be processed in this application, it should be noted that all embodiments mentioned below are equally applicable to other types of wafer workpieces.

[0034] Figure 2 for Figure 1 A schematic diagram of the hot plate module 10. Regardless of the process scenario, the uniformity of the airflow environment within the hot plate module 10 directly affects the final process result. In some processes, airflow is uneven, meaning that the velocity and pressure of the airflow differ in different areas of the substrate surface. Airflow uniformity is defined under specific scenarios, such as requiring consistent airflow velocity and pressure throughout the annular area when forming an isolation air curtain, or establishing a uniform suction field during auxiliary baking to remove volatiles. This unevenness can be described by the standard deviation of airflow parameters at different locations. Figure 2A concrete demonstration was provided, showing that the hot plate module 10 includes a module body 11, a carrier plate 12, and a plate cover 13. During processing, the substrate is placed on the carrier plate 12, and the plate cover 13 covers it. Intuitively, uneven airflow may occur during the supply of air to the carrier plate 12 and the exhaust of air from the plate cover 13. Under these circumstances, precise heat treatment of the substrate becomes challenging. The high requirement for airflow uniformity is particularly evident in the processing of small-size nodes. Process uniformity requires that the processing conditions at all points on the substrate be essentially consistent to ensure the yield and performance consistency of the final product.

[0035] like Figure 4 As shown, to solve the problem of airflow uniformity during substrate processing, specific designs are required for the structures of the carrier disk 12 and the disk cover 13. The carrier disk 12 is specifically a disk core assembly 100, equipped with an air supply assembly 120. The disk cover 13 is specifically a cover assembly 200, equipped with an exhaust structure. Taking air supply uniformity as an example, the air supply assembly 120 typically needs to generate uniform airflow.

[0036] like Figure 6 The schematic diagram is shown. To simultaneously provide pressure equalization for process gases, the gas supply component 120 included in the core assembly 100 utilizes a pre-charge chamber 124 to buffer the gas, achieving uniform gas supply and restoring the gas from an uneven state to uniformity before reaching the substrate. Figure 6 Taking the illustrated embodiment as an example, the gas supply assembly 120 includes an inner ring 121 and an outer ring 122, forming an annular gas outlet channel 123 between them. Based on this structure, gas can be ejected from the annular gas outlet channel 123. If an external gas source supplies gas through the air inlet channel 125, then under the designed pre-pressurization chamber 124 structure, the gas can be pre-pressurized by the gas supply assembly 120 to form a uniform air curtain, thereby achieving uniform airflow output.

[0037] Figure 6 This only illustrates one embodiment of the gas supply assembly 120 in this scheme. Generally, the inner ring 121 and the outer ring 122 are coaxially arranged to form a uniformly wide annular gas outlet channel 123 during operation. In an optimized design, a pre-pressurization chamber 124 is formed inside the gas supply assembly 120, which communicates with the annular gas outlet channel 123. If external gas enters, the gas pressure can be equalized by controlling the gas entry method, resulting in a uniform pressure distribution of the gas before ejection.

[0038] Figure 6This is a partially enlarged schematic diagram of the disk core assembly 100 of the carrier disk 12 in this embodiment. The disk core assembly 100 includes a disk body 110 and a gas supply assembly 120. Specifically, the gas supply assembly 120 forms an annular gas outlet channel 123 by the coaxial arrangement of an inner ring member 121 and an outer ring member 122. When process gas needs to be supplied, the gas enters the pre-charge chamber 124 through the gas inlet channel 125. Considering the need for reasonable layout and the convenience of gas pressure equalization, the outlet end of the gas inlet channel 125 is arranged facing the wall surface 1241 of the pre-charge chamber 124. Figure 6 As shown, after the gas enters through the inlet 1251, it first impacts the wall 1241, causing its flow direction to change. Independent impact and diffusion control of the gas flow can be achieved through the specific geometry of the pre-charge chamber 124.

[0039] When equalizing the gas pressure, the gas first enters the pre-pressurized chamber 124, allowing it to be buffered and expanded within the chamber. Then, the gas is controlled to impact the wall 1241 and diffuse along the chamber, thereby causing the gas pressure throughout the chamber to tend towards uniformity, restoring it from an uneven state to the required uniform state.

[0040] Based on the above embodiments, the disk core assembly 100 can preferably have a positioning element 126 disposed between the inner ring 121 and the outer ring 122. This mainly addresses the concentricity issue between the inner ring 121 and the outer ring 122. In the technical solutions of the above embodiments, the inner ring 121 and the outer ring 122 are essentially fixed only by an assembly relationship, which is a single fit and not conducive to maintaining concentricity over the long term, and the assembly stability is limited. In the improved solution, the positioning element 126 is placed between the inner ring 121 and the outer ring 122. During assembly, the positioning element 126 can ensure their concentricity, reducing the risk of uneven width of the annular air outlet channel 123 due to concentricity deviation and reducing the possibility of subsequent uneven air outlet, thereby correspondingly improving the stability of the process.

[0041] Figure 3 and Figure 5 The illustrated embodiment is merely one technical solution for achieving uniform exhaust gas distribution in the cover assembly 200 based on the structure of the flow equalization plate 220. In the structural design of the cover assembly 200, the flow equalization plate 220 typically has guide holes 221; however, it is also feasible to have a solid blocking area 222 directly below the exhaust port 211. Overall, as long as the airflow within the processing chamber 240 does not form vortices above the substrate during extraction, and the structural constraints are met, the uniformity of air extraction above the substrate can be guaranteed.

[0042] The aforementioned core assembly 100 and cover assembly 200 can be applied to the hot plate module 10. For example... Figure 1As shown, the hot plate module 10 can be applied to a semiconductor processing equipment 1. The semiconductor processing equipment 1 is equipped with a rack 2, and the rack 2 has a compartment 3 that can accommodate the hot plate module 10. The hot plate module 10 can be pushed into or pulled out of the compartment 3 as a whole. To achieve convenient pipeline connection, the rear of the hot plate module 10 is provided with a docking air port 310, which can optionally achieve a sealed docking with the equipment exhaust interface 4 on the rear wall of the compartment 3 via a flexible sealing gasket 311 or other means. The insertion and removal of the hot plate module 10 is mainly used for equipment maintenance or replacement. In the general process of the hot plate module 10, initially, the hot plate module 10 is outside the compartment 3. When installation is required, the hot plate module 10 is pushed into the compartment 3, and its docking air port 310 automatically docks with the equipment exhaust interface 4. During the above docking process, when the hot plate module 10 has completely entered the compartment 3, the docking structure is controlled to form an airtight connection between the two, thereby returning the equipment to the normal working state, that is, the installation operation is completed. After installation and functional verification are completed, the hot plate module 10 returns to normal working status in an orderly manner, completing a complete installation process.

[0043] The specific design of the semiconductor processing equipment 1 is not limited to the above embodiments. Several bays 3 can be flexibly arranged on the rack 2, for example... Figure 1 The design of the semiconductor processing device 1 with multiple compartments 3 is shown in the image. Other similar semiconductor processing device technologies are not limited to... Figure 1 As shown. In Figure 1 In this configuration, multiple compartments 3 are arranged sequentially in a vertical direction, and can be centrally managed by mounting them on the same rack 2. However, to improve exhaust efficiency, the exhaust ducts between compartments 3 are preferably connected in groups, meaning that the exhaust ports 4 of several compartments 3 are connected to a single, independent main exhaust pipe 5, without interference. This allows two or more groups of compartments 3 to exhaust without waiting for each other, potentially solving the pressure drop problem caused by excessively long main ducts, thereby improving the efficiency of exhaust operations. Figure 1 As shown, the two sets of compartments 3 can be arranged in layers within the rack 2. In this case, at least one of the two sets of compartments 3 is configured to be connected to a separate main exhaust pipe 5.

[0044] Corresponding to the aforementioned disk core assembly 100 or the hot plate module 10 having the disk core assembly, its pressure equalization method can be based on Figure 6 Explanation: The gas diffuses through the interaction between the intake channel 125 and the wall 1241 of the pre-charge chamber 124, thereby restoring the gas pressure in the pre-charge chamber 124 to the required uniform state.

[0045] The uniform gas supply method can first be implemented based on fluid dynamics design. Based on preliminary analysis of gas flow characteristics, at least the flow direction within the pre-pressurization chamber 124 is determined, and the pressure equalization target is clearly defined beforehand. According to the flow direction and pressure equalization target, the internal flow pattern of the pre-pressurization chamber 124 after gas is supplied from the inlet channel 125 is determined, so that the pressure gradient within the pre-pressurization chamber 124 gradually decreases due to gas diffusion. During this process, the pressure distribution within the pre-pressurization chamber 124 can be obtained through simulation or experiment. When the pressure distribution meets the required uniformity, the final structural design is determined, ensuring that the gas is maintained within the pre-pressurization chamber 124 under the required pressure distribution. In this embodiment, the gas pressure distribution is typically determined by the pressure values ​​at several points within the chamber, which can then be simulated using simulation software. In specific applications, computational fluid dynamics software can typically be used for simulation, or the pressure at different points within the same chamber can be determined using several pressure sensors, thereby determining the pressure field distribution.

[0046] The uniform gas supply method can also be determined by controlling the gas flow based on pre-known structural parameters, eliminating the need for pressure feedback from sensors during the pressure equalization process. The process involves determining the flow rate requirement of the heating plate module 10 under operating conditions based on other measurement inputs. Since the required uniformity index is generally known in advance, the dimensions of the pre-charge chamber 124 can obviously be determined before controlling the gas supply flow. The dimensions of the pre-charge chamber 124 can serve as the main parameter for gas pressure equalization control.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
