Latest Patents
One of his latest patents is a semiconductor device having a stress-reducing laminate and a method for manufacturing the same. This invention features a semiconductor device that includes a stress-reducing laminate. Grooves are formed on the surface of a material layer selected from a multilayer structure of the semiconductor device, such as a conductive layer. The cross sections of these grooves are semicircular or semi-elliptic, which helps to divide the stress applied to the conductive layer into vertical and horizontal components. This design effectively reduces the vertical stress on the conductive layer, preventing cracking due to stress and minimizing the stress transmitted to the underlying material layers.
Another significant patent is for a liquid crystal display that prevents vertical cross-talk by utilizing overlapping data lines. This invention involves a liquid crystal display and a production method where multiple data lines are formed on an insulating substrate, with gate lines arranged perpendicular to them. The design includes first and second common electrode lines that are parallel to the gate lines and divided into bars located on opposite sides of the data lines. A secondary common electrode is formed on the insulating film and overlaps the edges of the data lines, serving as an electric field blocking webbing.
