Latest Patents

Inagaki's latest patents include a semiconductor device having a SOI substrate and a fabrication method thereof. This semiconductor device features a semiconductor layer with a first surface and a second surface that is comparatively lower than the first surface. The device incorporates a first material layer formed over the second surface, which consists of an inorganic material with a hardness exceeding that of the semiconductor layer. Additionally, a second material layer is included, which has a hardness less than that of the first material layer, and is formed in a gap between the sidewall of the first material layer and the sidewall between the first and second surfaces. The first surface of the semiconductor layer is lapped until it is substantially flush with the top surface of the first material layer.

Another patent by Inagaki describes a method for producing a semiconductor device on a semiconductor layer provided on an insulator layer. This method involves providing an opening on the semiconductor layer to expose the top surface of the insulator layer, depositing a first material layer with a hardness exceeding that of the semiconductor layer, and patterning this layer. The method also includes depositing a second material layer that covers the semiconductor layer and fills the gap between the side wall of the patterned region and the side wall of the opening. The process concludes with lapping the top surface of the semiconductor layer until the top surface of the patterned region is exposed.
