[0083] Described herein is a technique for laser-assisted transfer of individual components from a thin, flexible dynamic release tape disposed on a support plate of a component transfer system. The dynamic release tape includes a multi-layer dynamic release structure disposed on a support layer, such as a backing. Each layer of the dynamic release structure can be specifically designed for one or more functions of the dynamic release structure, such as adhesion, optical properties, or mechanical properties. Laser-assisted transfer of individual components from a dynamic release tape disposed on a carrier substrate is also described.
[0084] 1A and 1B show a laser-assisted transfer process for high-throughput, low-cost, non-contact assembly of discrete components 102 onto rigid or flexible substrates. The term discrete component generally refers to any unit, e.g., electronic, electromechanical, photovoltaic, photonic, or optoelectronic component, module, or system that is part of, e.g., a product or electronic device, e.g., any semiconductor material with circuitry formed on a portion of the semiconductor material. In some examples, the discrete component can be a light-emitting diode (LED). The discrete component can be ultra-thin, i.e., a maximum thickness of 50 μm or less, 40 μm or less, 30 μm or less, 25 μm or less, 20 μm or less, 10 μm or less, or 5 μm or less. The discrete component can be ultra-small, i.e., a maximum length or width dimension of 300 μm or less per side, 100 μm or less per side, 50 μm or less per side, 20 μm or less per side, or 5 μm or less per side. The individual components can be extremely thin and compact.
[0085] 1A and 1B show a portion of a support fixture 100 of a component transfer system for laser-assisted transfer of an individual component 102. The support fixture 100 holds a flexible individual component assembly 108 in position for the laser-assisted transfer process. The support fixture (described in more detail below) can include a rigid support plate 106 mounted on a frame (not shown, described in more detail below). The frame provides stability to the rigid support plate 106. In some examples, the frame can be manipulated, for example, for alignment purposes. The individual component assembly 108 can be attached to the support plate 106 by suction, tensile stress, or other methods, as described in more detail below. The placement of the individual component assembly 108 on the support plate 106 is non-permanent, for example, thereby allowing the individual component assembly 108 to be removed from the support plate 106 after the laser-assisted transfer process is completed without damaging the support plate 106. The non-permanent mounting of the individual component assemblies 108 on the support plate 106 allows the support plate 106 to be utilized for multiple transfer processes involving multiple individual component assemblies 108 .
[0086] The discrete component assembly 108 includes a dynamic release tape 110 mounted on a wafer ring (not shown) to which discrete components 102 are adhered. Although only a single discrete component 102 is shown here, multiple discrete components 102 can be adhered to the dynamic release tape 110 and transferred by a component transfer system. The dynamic release tape (e.g., tape 110) is a tape that includes a flexible support layer 112 and a dynamic release structure 114 disposed on the flexible support layer 112. The tape is a thin, flexible material made up of one or more layers. The flexible support layer 112 contacts the support plate 106 of the support fixture 100, and the discrete components 102 are adhered to the dynamic release structure 114. The dynamic release structure 114 can be a multi-layer structure, such as a structure having two, three, four, or more than four layers, as described in more detail below.
[0087] 1B, in the laser-assisted transfer process, the backside of the support plate 106 is irradiated with radiation 116, such as light, e.g., a laser beam. Both the support plate 106 and the flexible support layer 112 of the dynamic release tape 110 are transparent to the wavelength of the radiation 116 (e.g., laser energy). An element that is transparent to a given wavelength is an element through which at least some radiation of the given wavelength passes. The radiation 116 passes through the support plate 106 and the flexible support layer 112 of the dynamic release tape 110 and impinges on an area of the dynamic release structure 114, causing a partial thickness of the dynamic release structure 114 to be ablated in the area where the radiation 116 impinges (referred to as the irradiated area). The ablation generates trapped gas, which expands and creates stress in the dynamic release structure 114. This stress deforms at least a portion of the material of the dynamic release structure 114, forming blisters 118. The blisters 118 exert a mechanical force on the individual components 102. When the mechanical force applied by the blister 118 is sufficient to overcome the adhesion between the individual components 102 and the dynamic release structure 114, the mechanical force applied by the blister 118 (combined with gravity) pulls the individual components away from the support plate 106 (e.g., downward) and transfers them to the target substrate 130.
[0088] The target substrate 130 can be positioned in close proximity to the individual components 102, for example, at a distance between about 5 μm and about 300 μm. Using a rigid support plate 106 to support the tape-based individual component assembly 108 helps to maintain a constant separation distance between the individual components 102 of the individual component assembly 108 and the target substrate 130, for example, by preventing sagging or other structural variations in the tape 110. In some examples, the support plate 106 can be provided with a high degree of surface flatness. For example, the support plate 106 can be machined with high precision.
[0089] In some laser-assisted transfer processes, the individual components are adhered to a rigid transparent carrier substrate by a dynamic release structure. The carrier substrate with the adhered individual components is provided to a component transfer system for laser-assisted transfer of the individual components. The component transfer system described herein incorporates a rigid transparent support plate into the component transfer system itself, allowing the individual components to be transferred from a tape rather than from a rigid carrier substrate, reducing the cost (e.g., in terms of materials, manufacturing, transportation, etc.) of the end-to-end individual component transfer process. For example, a rigid carrier substrate may be significantly more expensive than a dynamic release tape. Furthermore, the dynamic release tape is disposable, eliminating the associated costs of refurbishment of a rigid carrier substrate.
[0090] In some examples, the dynamic release tape used in the individual component transfer process is an unsupported tape. An unsupported tape is a tape that is not attached to a rigid substrate. In some examples, the unsupported tape can be placed on a rigid substrate for one or more steps of the individual component transfer process, but cannot be attached. For example, the unsupported tape can be placed on a rigid substrate during attachment of the individual components to the tape, during introduction into the component transfer system, or during laser-assisted transfer of the individual components.
[0091] In some examples, the dynamic release tape used in the individual component transfer process is not an unsupported tape, but instead is attached to a rigid substrate during attachment of the individual components to the tape, during introduction into the component transfer system, and during laser-assisted transfer of the individual components.
[0092] Further description of the laser assisted transfer process is provided in U.S. Patent Application Publication No. 2014 / 0238592, the contents of which are incorporated herein by reference in their entirety.
[0093] 2A and 2B show cutaway views of an exemplary support fixture 200 including a support plate 206 for positioning an individual component assembly 208 for a laser-assisted transfer process. The support plate 206 is a rigid plate that is transparent to wavelengths of radiation used in the laser transfer process, e.g., ultraviolet (UV) light. For example, the support plate 206 can be a glass plate, a quartz plate, or a plate of another material. The support plate 206 is mounted on a frame 220 of the support fixture. In some examples, as shown in FIGS. 2A and 2B, the frame 220 has an opening 221 to allow radiation to reach the support plate 206. In some examples, the frame 220 may not have an opening and may be transparent to the wavelengths of radiation so that the radiation is transmitted through the frame 220.
[0094] The individual component assembly 208 includes an unsupported dynamic release tape 210 mounted on a wafer ring 222, with the individual components 102 adhered to the dynamic release tape 210. For example, the dynamic release tape 210 can be stretched over the wafer ring 222. In the example of FIGS. 2A-2B, the dynamic release tape 210 includes a flexible support layer 212 having a multi-layer dynamic release structure 214 disposed thereon. The exemplary multi-layer dynamic release structure 214 includes a number of sub-layers 224a, 224b having adhesive, radiation absorbing, and foaming functions, and a component adhesive layer 226 that adheres to the individual components 102. The multi-layer dynamic release structure 214 is described in more detail below.
[0095] 2B , to place the individual component assembly 208 on the support plate 206 of the component transfer system, the wafer ring 222 is brought into contact with the frame 220 and the backside of the flexible support layer 212 of the dynamic release tape 210 is brought into contact with the support plate 206. Once placed, the top surface 223 of the wafer ring 222 is substantially level (e.g., aligned) with the top surface 207 of the support plate 206, such that the dynamic release tape 210 is substantially flat throughout its lateral extent.
[0096] For example, suction is applied by a suction source of the component transfer system through the air passage 228 to hold the dynamic release tape 210 against the support plate 206. For example, the air passage 228 can be defined through a thickness of the frame 220 of the component transfer system (as shown), can be defined through a thickness of the support plate 206, or can be defined through both the thickness of the frame 220 and the thickness of the support plate 206. Application of suction draws the dynamic release tape 210 tightly against the support plate 206, e.g., thereby causing the dynamic release structure 214 to become substantially flat.
[0097] As can be seen with reference to FIG. 10, in some examples, the support fixture 150 includes the frame 170 but does not include the support plate (e.g., does not include the support plate 206 as shown in FIGS. 2A and 2B). The wafer ring 222 of the individual component assembly 208 is mounted on the frame 170 of the support fixture 150, and the dynamic release tape 210 is optionally left unsupported for the laser-assisted transfer process. When the dynamic release tape 210 has sufficient rigidity, such as sufficient rigidity to maintain a substantially planar configuration for the duration of the laser-assisted transfer process, the laser-assisted transfer can be performed directly from the unsupported dynamic release tape 210. For example, the dynamic release tape 210 can have sufficient rigidity to reduce the maximum slippage of the dynamic release tape 210 in a direction z perpendicular to the plane of the tape 210 to less than a threshold amount, e.g., less than 20 μm, less than 10 μm, or less than 5 μm, when the individual component assembly 208 is mounted on the frame 170.
[0098] 3 shows a cutaway view of an exemplary support fixture 300 including a support plate 306 for positioning the individual component assemblies 208 for a laser assisted transfer process. The support plate 306 is a rigid plate that is transparent to wavelengths of radiation used in the laser transfer process, e.g., UV light. The support plate 306 is mounted on a frame 320 of the support fixture 300. The frame 320 has an opening 321 to allow the radiation to reach the support plate 306. In some examples, the frame 320 can be transparent to the wavelengths of radiation such that the radiation is transmitted through the frame 320.
[0099] 3, when the individual component assembly 208 is placed on the support fixture 300, the top surface 223 of the wafer ring 222 is at a lower level than (e.g., offset from) the top surface 307 of the support plate 306. For example, the frame 320 of the support fixture 300 can be offset from the top surface of the support plate 306 by an amount such that when the individual component assembly 208 is placed on the support plate, the support plate 306 and the wafer ring 222 are still offset. This offset introduces a tensile stress to the dynamic release tape 210 that holds the dynamic release tape 210 against the support plate 306, e.g., causing the dynamic release structure 214 to become substantially flat. The amount of tensile stress, and therefore the force to hold the dynamic release tape 210 against the support plate 306, can be controlled by varying the height difference between the top surface 223 of the wafer ring 222 and the top surface 307 of the support plate 306.
[0100] In some examples, other techniques can be used to position the dynamic release tape 210 on the support plate of the component transfer system, such as by using magnetic forces, electrostatic forces, techniques involving mechanical fastening, or other techniques.
[0101] 4 illustrates an example of a component transfer system 450. The component transfer system 450 includes a support fixture 400 having a support plate 406 mounted on a frame 420. The support fixture 400 is positioned such that an individual component assembly 408 is held on the support plate 406. The individual component assembly 408 includes a dynamic release tape 410 having adhered individual components 102 thereto, the dynamic release tape 410 being mounted on a wafer ring 422, e.g., stretched over the wafer ring 422. For example, the wafer ring 422 is positioned on a frame 420, and the stretched dynamic release tape 410 is held against the support plate 406. The individual component assembly 408 can be illuminated with radiation (e.g., light such as UV light) from a light source 452, e.g., a laser. The light from the light source 452 can be manipulated, e.g., focused, by an optical element 454, e.g., a lens, positioned between the light source 452 and the support plate 406. The frame 420 has an opening 421 to allow radiation from the light source 452 to reach the support plate 406. A substrate holder 432 holds a target substrate 430 onto which discrete components are to be transferred by the laser assisted transfer process.
[0102] In some examples, such as when the support fixture 400 is configured to hold the individual component assemblies against the support plate 406 by applying suction, the component transfer system 450 may include a suction source 434 fluidly connected (e.g., by piping, not shown) to one or more air flow paths (not shown) in the support plate 406 or frame 420.
[0103] 5 illustrates an example of a component transfer system 550 having a light source 552 and an optical element 554. The component transfer system 550 includes a support fixture 500 that includes a frame 520. No support plate is mounted on the frame 520. An individual component assembly 508 is held on the frame 520, and the individual component assembly 508 includes a dynamic release tape 510 mounted on a wafer ring 522. In this configuration, the wafer ring 522 of the individual component assembly 508 is placed on the frame 520, and the dynamic release tape 510 is an unsupported tape during the laser assisted transfer process (i.e., a tape that is not supported by a rigid substrate or support plate). An individual component 102 is transferred onto a target substrate 530 held by a substrate holder 532.
[0104] In some examples, the component transfer system 450, 550 can be configured to transfer multiple individual components in parallel or can be configured to have a single component transfer mode and a multi-component transfer mode as described in more detail in WO2018 / 231344, filed April 25, 2018, the contents of which are incorporated by reference in their entirety herein.
[0105] 6, in some examples, the individual components 602 can be transferred to the dynamic release tape 610 after the dicing process. For example, using standard wafer processing techniques for wafer dicing, a wafer 630 including one or more electronic components (e.g., integrated circuits) is adhered (650) to a dicing tape 632 and diced (652) to form the individual components 602. For example, the dicing tape 632 can be attached onto a wafer ring. In some examples, the dicing process can include laterally stretching the dicing tape to separate the individual components 602, for example, by rolling the dicing tape 632 out onto the wafer ring.
[0106] The individual components 602 are transferred (654) onto the dynamic release tape 610 and the dicing tape 632 is removed (656), leaving the individual components 602 adhered to the dynamic release tape 610. For example, the individual components 602 can be adhered to a component adhesive layer (described below) of the dynamic release tape 610. The dynamic release tape 610 with the adhered individual components 602 is attached (658) to a transparent rigid support plate 606 of a component transfer system for laser assisted transfer of the individual components 602 onto a target substrate. For example, the flexible support layer of the dynamic release tape 610 is attached to the support plate, for example, by suction, tensile stress, or otherwise.
[0107] As can be seen with reference to FIG. 7, in some examples, the individual components 702 can be diced directly on the dynamic release tape 710. A wafer 730 including one or more semiconductor dies (e.g., integrated circuits) is attached (750) to the dynamic release tape 710, e.g., to a component adhesive layer of the dynamic release tape 710. The attached wafer 730 is diced (752) to form the individual components 702, e.g., using standard wafer processing techniques for wafer dicing. For example, the dynamic release tape 710 can be attached onto a wafer ring. In some examples, the dynamic release tape 710 is stretchable, and the dicing process can include laterally stretching the dynamic release tape 710 to separate the individual components 702, e.g., by unfolding the dynamic release tape over the wafer ring.
[0108] The dynamic release tape 710 with the individual components 702 attached thereto is attached (754) to a transparent, rigid support plate 706 of a component transfer system for laser-assisted transfer of the individual components 702 onto a target substrate. For example, a flexible support layer of the dynamic release tape 710 is attached to the support plate, for example, by suction, tensile stress, or otherwise.
[0109] In the process of FIG. 7, the step of transferring the diced individual components 702 from the dicing tape to the dynamic release layer tape is not included, making the process of FIG. 7 streamlined and efficient.
[0110] 8A-8C, the dynamic release layer tapes 800, 820, 840 can be multi-layer tapes having a flexible support layer 812 and a multi-layer dynamic release structure 814, 834, 854 disposed on the flexible support layer 812, respectively. The individual components 802 can be adhered to the dynamic release structures 814, 834, 854 by a component adhesive layer 808 that forms part of each multi-layer dynamic release structure 814, 834, 854. The multi-layer dynamic release structures 814, 834, 854 can be formed by varying the number of layers with various compositions and functions. As shown in FIG. 8A-8C, the dynamic release layer tapes 800, 820, 840 can be disposed on a rigid support such as a support plate 806 of a component transfer system that is transparent to the radiation used in the laser-assisted transfer process. In some examples, the dynamic release layer tapes 800, 820, 840 can be used in other environments, such as by being attached to a wafer ring or otherwise used.
[0111] The flexible support layer 812 is a thin, flexible film that is transparent to the radiation used in the laser-assisted transfer process, for example, UV light. For example, the flexible support layer 812 can be a polymer film, such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), or poly(methyl methacrylate) (PMMA). The flexible support layer 812 is thin and flexible enough to allow the dynamic release layer tape 800, 820, 840 to be manipulated, for example, rolled, bent, or stretched, without cutting the tape. The presence of the flexible support layer 812 allows the dynamic release layer tape 800, 820, 840 to be an unsupported tape that has sufficient mechanical integrity to be handled, for example, without being attached to a rigid substrate.
[0112] 8A , in some examples, the dynamic release structure 814 of the dynamic release layer tape 800 can be a three-layer structure having an absorbent adhesive layer 804 disposed on a flexible support layer 812 and an active layer 805, such as a foam layer (shown in FIG. 8A ), disposed on the absorbent adhesive layer 804. A component adhesive layer 808 is disposed on the active layer 805.
[0113] The absorbing adhesive layer 804 has two functions: to bond the active layer 805 to the flexible support layer 812 and to absorb energy from irradiation during the laser assisted transfer process. For example, the absorbing adhesive layer 804 may absorb at least 90%, at least 95%, at least 98%, or at least 99% of the energy incident on the absorbing adhesive layer 804, e.g., to prevent the radiation from reaching and potentially damaging individual components adhered to the tape 800.
[0114] Energy absorption by the absorbing adhesive layer 804 cauterizes the layer, generating gas. The generated gas induces a mechanical response in the adjacent active layer 805. For example, as shown in Figure 8A, the active layer 805 can be a foam layer that forms blisters in response to gas generation (e.g., as shown in Figure 1B).
[0115] 8B, in some examples, the dynamic release structure 834 of the dynamic release layer tape 820 can be a three-layer structure having an adhesive layer 824 disposed on the flexible support layer 812 and an active layer 826, such as an absorbent foam layer (as shown in FIG. 8B), disposed on the adhesive layer 824. The component adhesive layer 808 is disposed on the active layer 826.
[0116] The adhesive layer 824 exhibits sufficient adhesion to bond the active layer 826 to the flexible support layer 812. In the example of FIG. 8B, the active layer 826 is an absorbing foam layer. The active layer 826 absorbs energy from irradiation during the laser assisted transfer process and generates gas that induces a mechanical response, such as the formation of blisters, in the active layer 826. For example, the active layer 826 can absorb at least 90%, at least 95%, at least 98%, or at least 99% of the incident energy.
[0117] 8C , in some examples, the dynamic release structure 854 of the dynamic release layer tape 840 can be a four-layer structure having an adhesive layer 844 disposed on the flexible support layer 812 and an active layer structure 846 disposed on the adhesive layer 844. The component adhesive layer 808 is disposed on the active layer structure 846.
[0118] The adhesive layer 844 exhibits sufficient adhesion to bond the active layer structure 846 to the flexible support layer 812. The active layer structure 846 includes two layers: an absorbing layer 848 and a foam layer 850. The absorbing layer 848 absorbs energy from irradiation during the laser assisted transfer process and generates a gas. For example, the absorbing layer 848 can absorb at least 90%, at least 95%, at least 98%, or at least 99% of the incident energy. The generation of gas induces a mechanical response in the foam layer 850, such as the formation of blisters.
[0119] The dynamic release structures (e.g., dynamic release structures 814, 834, 854) have multiple functions, such as adhesion to a flexible support layer, internal adhesion between layers, absorption of incident radiation, and mechanical response (e.g., foaming), etc. The multi-layer nature of the dynamic release structures 814, 834, 854 can allow each layer to be specifically designed to achieve one or more of these functions.
[0120] In the example of FIG. 8A, the absorbing adhesive layer 804 can be designed to adhere to the support layer 812 and absorb incident radiation and generate a sufficient amount of gas to form blisters in the active layer 805. In some examples, the absorbing adhesive layer 804 can be designed to adhere to the active layer 805 with sufficient adhesion to promote internal adhesion and, for example, to at least partially avoid delamination of the blisters. Delamination of the blisters may result in larger diameter blisters that may affect the transfer of individual components at nearby locations, for example individual components that are not to be transferred. In designing the absorbing adhesive layer 804, the optical and adhesive properties of the layer can be the primary focus of the design, while the mechanical properties of the layer, such as the strength or modulus of the layer, can be secondary to the design. In contrast, the thickness and composition of the active layer 805 can be designed to prioritize mechanical properties, for example, to achieve a desired foaming reaction, while the optical and adhesive properties of the layer can be secondary. In some examples, the active layer 805 can be designed to allow formation of blisters of a target size, have mechanical properties that do not cause the blisters to rupture, and prevent gas generated by the absorbing adhesive layer 804 from escaping the dynamic release structure 814. For example, the target size of the blisters can be a height-to-diameter ratio of about 1, with a base diameter no greater than about 3 times the diameter of the irradiating beam (e.g., laser beam). In a particular example, the active layer 805 can be a polymer film, e.g., a PET or polyimide film, with a thickness between about 2 μm and about 5 μm.
[0121] Furthermore, in the dynamic release structure 814 of FIG. 8A, the active layer 805 itself does not absorb energy and is therefore not partially ablated. Instead, ablation occurs in the adjacent absorbing adhesive layer 804. Because no ablation occurs in the active layer 805, the thickness of the active layer 805 is not affected by the amount of laser energy delivered to the blister location, i.e., the active layer 805 is not thinned by irradiation. Separating the ablation and blister formation into two different layers in this manner allows for the use of higher pulse energies to form larger blisters.
[0122] In some examples, such as when transferring individual components 802 from a dicing tape (as in FIG. 6 ) or other source substrate to a dynamic release layer tape, when a wafer is diced directly on the dynamic release layer tape to form the individual components 802, the component adhesive layer 808 can be designed to have an adhesive strength greater than the force holding the individual components 802 to their source substrate. In some examples, a relatively low adhesion between the component adhesive layer 808 and the individual components 802 can contribute to increased precision during the laser-assisted transfer process. The component adhesive layer 808 can be designed to have an adhesive strength as low as possible, while being strong enough to keep the individual components adhered to the dynamic release layer tape prior to the laser-assisted transfer process. In some examples, to meet these mutually contradictory criteria for the component adhesive layer 808 to have both high and low adhesive strength, the component adhesive layer 808 can be designed to have an adhesive strength that can be modified by application of a stimulus such as UV light or heat. The initial strong adhesion of the component adhesive layer 808 can facilitate reliable transfer of the individual components 802 from their source substrate to the dynamic release layer tape. The initial adhesion of component adhesion layer 808 can also support the wafer during the dicing process to form the individual components. Prior to the laser assisted transfer process, a stimulus can be applied to reduce the adhesion between component adhesion layer 808 and individual components 802 to a level that can contribute to the accuracy of component placement during transfer.
[0123] 9A-9C, in some examples, the multilayer dynamic release structures 914, 934, 954 can be affixed to a rigid carrier substrate 910, such as a glass carrier substrate. Individual components 902 can be adhered to the rigid carrier substrate 910 by the dynamic release structures 914, 934, 954 to form individual component assemblies 900, 920, 940. The individual components 902 can be directly transferred from the rigid carrier substrate 910 to a target substrate by a laser assisted transfer process.
[0124] The dynamic release structure can be provided as an unsupported tape and can be applied as a tape onto a carrier substrate 910, for example, by roll coating or other tape application methods. In some examples, the dynamic release structure can be spin coated onto a carrier substrate. Application of a dynamic release structure in tape form onto a carrier substrate can have advantages over spin coating, such as reduced cost, reduced processing labor, and more efficient application.
[0125] The dynamic release structures 914, 934, 954 provided in tape form for application to the rigid carrier substrate 910 can be multi-layer structures as described above with respect to Figures 8A-8C.
[0126] 9A , in some examples, the dynamic release structure 914 can be a three-layer structure having an absorbent adhesive layer 904 adhered to a rigid carrier substrate 910. An active layer 906, such as a foam layer (as shown in FIG. 9A ), is disposed on the absorbent adhesive layer 904. A component adhesive layer 908 is disposed on the active layer 906.
[0127] The absorbing adhesive layer 904 has two functions: to bond the active layer 906 to the rigid carrier substrate 910 and to absorb energy from irradiation during the laser assisted transfer process. The absorption of energy by the absorbing adhesive layer 904 cauterizes the layer and generates gas. The generated gas induces a mechanical response in the adjacent active layer 906. For example, as shown in FIG. 9A, the active layer 906 can be a foam layer that blister in response to gas generation, causing the transfer of the discrete components 902.
[0128] 9B, in some examples, the dynamic release structure 934 can be a three-layer structure having an adhesive layer 924 that adheres to a rigid carrier substrate 910 and an active layer 926, such as an absorbing foam layer (as shown in FIG. 9B), disposed on the adhesive layer 924. A component adhesive layer 908 is disposed on the active layer 926. The adhesive layer 924 exhibits sufficient adhesion to adhere to the carrier substrate 910. In the example of FIG. 9B, the active layer 926 is an absorbing foam layer that absorbs energy from irradiation during the laser assisted transfer process and generates a gas that induces a mechanical response, such as the formation of blisters, in the active layer 926.
[0129] 9C, in some examples, the dynamic release structure 954 can be a four-layer structure having an adhesive layer 944 that adheres to the rigid carrier substrate 910 and an active layer structure 946 disposed on the adhesive layer 944. The component adhesive layer 908 is disposed on the active layer structure 946. The active layer structure 946 has two layers, an absorbing layer 948 and a foam layer 950. The absorbing layer 948 absorbs energy from irradiation during the laser assisted transfer process and generates a gas. The generation of gas induces a mechanical response in the foam layer 950, such as the formation of blisters.
[0130] The individual layers of the multi-layer dynamic release structure can be designed to achieve the desired functionality described above with respect to Figures 8A-8C. For example, the adhesive layers 904, 924, 954 that adhere to the carrier substrate 910 can be designed to have low enough adhesion to the carrier substrate to allow for easy removal, facilitating refurbishment of the carrier substrate after the laser transfer process is complete.
[0131] Although several embodiments have been described, it will be understood that various modifications may be made without departing from the spirit and scope of the present invention. For example, some of the steps described above are order-independent and therefore may be performed in an order different from that described above.
