Latest Patents

Sato's latest patents focus on a manufacturing method of SOI substrates. This innovative method is designed to be practical even when using a supporting substrate with a low allowable temperature limit. The process involves forming a separation layer at a specific depth within a semiconductor substrate. A first heat treatment is performed when the semiconductor layer on the separation layer is bonded to the supporting substrate and subsequently separated. Following this, a second heat treatment is applied to the supporting substrate, ensuring that the temperature does not exceed the strain point of the substrate. When both heat treatments are conducted at the same temperature, the duration of the second heat treatment can be extended.
