Latest Patents

One of Yamaguchi's latest patents is a method of forming a shallow and deep trench isolation (SDTI) suitable for silicon on insulator (SOI) substrates. This method involves forming deep trenches through an SOI layer while preserving the underlying buried oxide (BOX) layer. The trenches are filled with electrical isolating materials and etched back to achieve a planarized top surface. Following this, an active nitride layer is deposited, and shallow trenches are formed using a low selectivity etch. This innovative approach allows for subsequent processing, including filling the shallow trench, annealing, and chemical-mechanical polishing.

Another notable patent is related to the fabrication of a semiconductor device using a tri-layer structure. This invention describes a semiconductor device made from a body of semiconductor material with layers of dielectric and conductive materials. The design ensures that the second layer of conductive material maintains an electrically conductive connection with the body of the semiconductor material, enhancing the device's performance.
