Abstract:
1. A method of fabricating strained silicon devices for transfer to glass for display applications, comprising: preparing a wafer having a silicon substrate thereon; forming a relaxed SiGe layer on the silicon substrate; forming a strained silicon layer on the relaxed SiGe layer; fabricating an IC device on the strained silicon layer; depositing a dielectric layer on the wafer to cover the IC device; smoothing the dielectric; implanting ions to form a defect layer; cutting the wafer into individual silicon dies; preparing a glass panel and the silicon dies for bonding; bonding the silicon dies onto the glass panel to form a bonded structure; annealing the bonded structure; splitting the bonded structure along the defect layer; removing the remaining silicon layer from the silicon substrate and relaxed SiGe layer on the silicon die on the glass panel; and completing the glass panel circuitry.
