Latest Patents

Yagi's latest patents include a method for manufacturing a bonded SOI wafer. This innovative method involves bonding a bond wafer and a base wafer, each composed of a silicon single crystal, via an insulator film. The process includes depositing a polycrystalline silicon layer on the bonding surface of the base wafer, polishing it, and then bonding it to the bond wafer. This method effectively prevents single-crystallization of polycrystalline silicon while minimizing warpage in the base wafer.

Another notable patent is a method for manufacturing an SOI wafer, which increases the thickness of the SOI layer by growing an epitaxial layer on the existing SOI layer. This process ensures that the reflectivity of the surface of the SOI wafer falls within a specific range during the epitaxial growth, resulting in a high-quality SOI wafer with fewer slip dislocations.
