Patent number: 6290804Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of introducing energetic particles (22) in a selected manner through a surface of a donor substrate (10) to form a pattern at a selected depth (20) underneath the surface. The particles have a concentration sufficiently high 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.Type: GrantFiled: February 20, 1998Date of Patent: September 18, 2001Assignee: Silicon Genesis CorporationInventors: Francois J.

Patent number: 6274240Abstract: A method of forming electrically insulated magnet wire and a coil formed therefrom. The method involves feeding a flexible electrical insulation tape along a path which converges with a path along which the wire to be wrapped is conveyed. Along the tape travel path at a location upstream of the point where the tape and wire converge, a quantity of heat activated adhesive that has been heated to a sticky state is applied to the passing tape. Then, before the adhesive coating sets, the adhesive coated tape reaches the point of convergence with the wire and is adhered to the wire to provide an electrical insulating wire wrap. The method of the invention provides for a longitudinal, partial wrapping of a conductor wire that furnishes suitable turn-to-turn insulation in coils formed with the wrapped wire.Type: GrantFiled: September 17, 1998Date of Patent: August 14, 2001Assignee: Alconex Specialty Products, Inc.Inventor: C.
