Latest Patents

Ohnishi's latest inventions include a notable patent for a semiconductor device featuring a pad-disposition restriction area. In this design, input/output cells are meticulously arranged adjacent to a corner cell on the semiconductor chip's surface, with electrode pads specifically formed on these cells. The configuration utilizes a zigzag pad arrangement, creating both inner and outer pad arrays. Importantly, certain electrode pads within the inner pad array are excluded from specific areas adjacent to the corner cell. This strategic decision simplifies the interconnect pattern of a carrier, which is bump-bonded to the semiconductor chip, thus preventing overly complex vias.

Another significant patent focuses on the same aspects of input/output cells and electrode pad arrangements, showcasing Ohnishi's commitment to refining semiconductor device layout for enhanced functionality.
