Abstract:
1. A method of fabricating a semiconductor structure or device, comprising: bonding a first layer of semiconductor material to a substrate using a bonding layer; selecting the substrate to comprise a material that exhibits a coefficient of thermal expansion higher than a coefficient of thermal expansion exhibited by the first layer of semiconductor material; depositing a second layer of semiconductor material over the first layer of semiconductor material while the first layer of semiconductor material is supported on the bonding layer and the bonding layer is in a viscous state; cooling the first layer of semiconductor material, second layer of semiconductor material, the bonding layer, and the substrate after depositing the second layer of semiconductor material over the first layer of semiconductor material; and compressively straining the first layer of semiconductor material using thermal contraction of the substrate while cooling the first layer of semiconductor material, the second layer of semiconductor material, the bonding layer, and the substrate.
