Latest Patents

Among Kinugasa's most recent innovations are two notable patents. The first invention is a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) with a graded gate oxide layer. This design incorporates a smile oxide film, which serves as a gate oxide film positioned under a three-layer poly-metal gate composed of a doped polysilicon layer, a tungsten layer, and a SiON layer. The unique aspect of this design is that the film thickness varies, being larger beneath the edges of the poly-metal gate than in the center. Complementarily, an anti-oxidizing film covers the poly-metal gate entirely, enhancing the device's reliability.

The second patent describes a semiconductor device featuring a potential fuse, along with its manufacturing methods. This device consists of an active region located on a semiconductor substrate, separated by several isolation regions. With varying thicknesses, a plurality of surface insulating films is created, followed by the formation of conductive films. A particularly thin insulating film can be induced to break down, functioning as an electric fuse during device operation.
