  • Patent number: 7351644
    Abstract: A method for fabricating one or more devices, e.g., integrated circuits. The method includes providing a substrate (e.g., silicon), which has a thickness of semiconductor material and a surface region. The substrate also has a cleave plane provided within the substrate to define the thickness of semiconductor material. The method includes joining the surface region of the substrate to a first handle substrate. In a preferred embodiment, the first handle substrate is termed a “thin” substrate, which provides suitable bonding characteristics, can withstand high temperature processing often desired during the manufacture of semiconductor devices, and has desirable de-bonding characteristics between it and a second handle substrate, which will be described in more detail below. In a preferred embodiment, the first handle substrate is also thick enough and rigid enough to allow for cleaving according to a specific embodiment.

  • Patent number: 7348258
    Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of forming a stressed region in a selected manner at a selected depth (20) underneath the surface. An energy source such as pressurized fluid 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.

  • Publication number: 20080038901
    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.

  • Publication number: 20070087531
    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.
