Method of Transferring an Ultra-Thin Layer of Crystalline Material with High Crystalline Quality

Abstract
With the acceleration of new technology nodes and the resulting industry shift to advanced materials that provide enhanced device performance and low power consumption, silicon-on-insulator (SOI) wafer technology has become a critical, enabling technology. This invention provides a revolutionary method of transferring an ultra-thin layer of crystalline material with high crystalline quality.

Application(s)
• Silicon on insulator (SOI) wafers
• Embedded processors
• Semiconductors
• Integrated circuits
• Silicon-on-quartz
• Silicon-on-glass

Advantages
• Better control of layer thickness
• Improved quality of the thin layer
• Improved smoothness of the thin layer
• Less transfer defects
