Latest Patents

Naota Tate holds a patent for a "Method for producing SOI wafer and SOI wafer." This patent describes a method that utilizes the hydrogen ion delamination technique. The process involves bonding a base wafer with a bond wafer that has a micro bubble layer formed through gas ion implantation. A key aspect of this method is the delamination of a wafer with an SOI layer at the micro bubble layer boundary. After the delamination, the wafer undergoes a two-stage heat treatment in an atmosphere containing hydrogen or argon, utilizing a rapid heating/rapid cooling apparatus (RTA) and a batch processing type furnace. This innovative approach improves the surface roughness of the SOI layer and efficiently produces SOI wafers free from pit generation due to crystal-originated particles (COPs) with high throughput.
