    摘要: A method and system for cleaving a film of material utilizing thermal flux. The method includes providing a substrate having a face and an underlying cleave region including a prepared initiation region. Additionally, the method includes subjecting the initiation region to a first thermal flux to form a cleave front separating the cleave region of the substrate to a film portion and a bulk portion. The method further includes subjecting an area of the bulk portion substantially in the vicinity of the cleave front to a second thermal flux to cause a temperature difference above and below the cleave region for inducing a propagation of the cleave front expanding the film portion to the area at the expense of the bulk portion. Furthermore, the method includes determining a scan path for the second thermal flux based on the cleave front. Moreover, the method includes scanning the second thermal flux to follow the scan path to further propagate the cleave front.

    摘要: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of introducing energetic particles (22) through a surface of a donor substrate (10) to a selected depth (20) underneath the surface, where the particles have a relatively high concentration to define a donor substrate material (12) above the selected depth. An energy source is directed to a selected region of the donor substrate to initiate a controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving action provides an expanding cleave front to free the donor material from a remaining portion of the donor substrate.

    摘要: A film of material may be formed by providing a semiconductor substrate having a surface region and a cleave region located at a predetermined depth beneath the surface region. During a process of cleaving the film from the substrate, shear in the cleave region is carefully controlled. According to certain embodiments, an in-plane shear component (KII) is maintained near zero, sandwiched between a tensile region and a compressive region. In one embodiment, cleaving can be accomplished using a plate positioned over the substrate surface. The plate serves to constrain movement of the film during cleaving, and together with a localized thermal treatment reduces shear developed during the cleaving process. According to other embodiments, the KII component is purposefully maintained at a high level and serves to guide and drive fracture propagation through the cleave sequence. In one embodiment, the high KII component is achieved by adiabatic heating of silicon through exposure to E-beam radiation, which imparts a highly abrupt thermal gradient and resulting stress at a precisely defined depth in the silicon.
