  • Patent number: 7759217
    Abstract: 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.

Additionally, the method includes processing the silicon ingot material to free the thickness of detachable material at a vicinity of the cleave region and causing formation of a free-standing thickness of material characterized by a carrier lifetime about 10 microseconds and a thickness ranging from about 20 microns to about 150 microns with a thickness variation of less than about five percent. Furthermore, the method includes treating the free-standing thickness of material using a thermal treatment process to recover the carrier lifetime to about 200 microseconds and greater.

  • Publication number: 20100055874
    Abstract: 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 to achieve controlled propagation by either KII or energy propagation control. According to certain embodiments, an in-plane shear component (KII) is maintained near zero by adiabatic heating of silicon through exposure to E-beam radiation. According to other embodiments, a surface heating source in combination with an implanted layer serves to guide fracture propagation through the cleave sequence.

  • Publication number: 20090277314
    Abstract: 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.

  • Publication number: 20090258496
    Abstract: A method of manufacturing an integrated circuit on semiconductor substrates, e.g., silicon wafer. The method includes providing a semiconductor substrate characterized by a first lattice with a first structure and a first spacing. In a specific embodiment, the semiconductor substrate has an overlying film of material with a second lattice with a second structure and a second spacing, the second spacing placing the film of material in a strain mode characterized by a first tensile and/or compressive mode along a single film surface crystal axis across a first portion of the film of material relative to the semiconductor substrate with the first structure and the first spacing. The method patterns a predetermined region of the first portion of the film of material to cause the first tensile and/or compressive mode in the first portion of the film of material to change to a second tensile and/or compressive mode in a resulting patterned portion of the first portion of the film of material.

  • Patent number: 7479441
    Abstract: Embodiments in accordance with the present invention relate to methods and apparatuses for bonding together substrates in a manner that suppresses the formation of voids between them. In a specific embodiment, a backside of each substrate is adhered to a front area of flexible, porous chuck having a rear area in pneumatic communication with a vacuum. Application of the vacuum causes the chuck and the associated substrate to slightly bend. Owing to this bending, physical contact between local portions on the front side of the flexed substrates may be initiated, while maintaining other portions on front side of the substrates substantially free from contact with each other. A bond wave is formed and maintained at a determined velocity to form a continuous interface joining the front sides of the substrates, without formation of voids therebetween.
