A Tucson high-tech firm and a major Japanese glass company have formed a new venture to develop semiconductor packaging using ultra-thin glass.
nMode Solutions Inc. of Tucson and Tokyo-based Asahi Glass Co., Ltd. have invested $2.1 million to co-found a subsidiary business, Triton Micro Technologies.
The new company will develop technology to form connections, called interposers, through thin glass to make a new generation of vertically stacked, “2.5-D” and “3-D” semiconductor devices.
Interposers allow the creation of a high number of electrical connections between a silicon chip and a printed circuit board — a key to the space-saving, stacked semiconductor designs, the companies said in a news release.
The new company, headquartered in Tucson with a manufacturing facility planned in California, will combine nMode’s interposer technology with materials technology and micro-hole drilling techniques from Asahi Glass, part of the Mitsubishi group of Japanese industrial companies.
