Latest Patents

Morita's recent contributions include two noteworthy patents:

1. **Method for Manufacturing Semiconductor Device Isolation Region** - This patent discusses a technique in which an insulation material is applied to a semiconductor substrate. A groove is meticulously created to transition from the material film to the substrate, which is later filled with a first insulation film. Utilizing this film as an etching mask allows for the removal of the material film, resulting in a distinctive projecting portion. A second insulation film is then sculpted on the side of this portion, taking a sloped form from the top to the main surface.

2. **Method of Manufacturing Semiconductor Device** - This patent outlines a procedure aimed at achieving a planar surface on semiconductor substrates characterized by unevenness. Here, a burying film is laid across the surface to cover any convex portions, followed by the formation of a stopper layer over the concave sections. The burying film is then uniformly polished until the convex surfaces are revealed, facilitating the creation of a precisely planarized structure.
