Latest Patents

Wen Kuei Hsu holds a patent for a self-aligned wet etching process. This process involves etching a substrate that has an etch protection layer on its surface to create multiple trenches that are spaced apart. The method includes the sequential formation of an insulating layer, an etch stop layer, and a primary insulator within each trench. The primary insulator is designed to fill an accommodation space surrounded by the etch stop layer. During the wet etching process, the etch stop layer serves to protect the primary insulator from being etched away, thereby achieving anisotropic wet etching. This innovation enhances the contact areas for electrical connections with external circuits and prevents short circuits caused by excessive etching of the primary insulators.
