Chinese 3D Nand flash memory manufacturer YMTC recently signed a license agreement with the U.S. Xperi to access a set of semiconductor intellectual properties of DBI hybrid bonding technology.

Xperi is a U.S. San Jose-based technology license company. Craig Mitchell, President of Invensas, a wholly-owned subsidiary of Xperi, said: "The DBI hybrid bonding technology is a key enabling technology for the current and future generations of 3D NAND flash memory with high-performance and large-capacity. We are proud to provide YMTC with our basic intellectual property rights and looking forward to further expanding our partnership."

YTMC (Yangtze Memory Technologies Co., Ltd.长江存储) in Wuhan, central China Hubei province, is the designer and manufacturer for the first 3D NAND flash memory in China. It was established in July 2016, with the Chinese government investment fund being a major shareholder. In October 2017, YMTC successfully designed and manufactured China's first 3D NAND flash memory by combining independent R&D and international cooperation. The company provides products and solutions such as 3D NAND flash memory wafers, embedded memory chips, and consumer and enterprise SSDs (Solid State Drives).

Xperi Holding Corp (Xperi) is formerly known as Tessera Holding Corporation, founded in 1990 by former IBM research scientists. It licenses technologies and intellectual property in mobile computing, communications, memory and data storage, and three-dimensional integrated circuit (3D IC) technologies.

Hybrid bonding 3D integration technology is increasingly utilized in various semiconductor devices, such as sensors, memories, and logic devices, to enable enhanced performance and functionality while reducing size and cost, according to Xperi.

When applying to 3D NAND, DBI hybrid bonding technology can disaggregate the memory arrays and logic circuitry to provide the best wafer nodes for each application. According to Xperi.

Xperi has invented many technologies, which have been integrated through its brands of DTS, HD Receiver, IMAX, Invensas, and Tivo into billions of consumer devices, media platforms, and semiconductors worldwide.
