New breakthrough of over 65W fast charging, mass production of 0.35 micron 650V gallium nitride process by advanced companies in the world.

Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com November 23, the world's advanced company announced that its leading 8-inch 0.35um 650V new substrate high-voltage gallium nitride process (GaN-on-QST) has completed the first batch of product system and reliability verification on the client, and officially entered mass production, becoming the first company to mass-produce this technology in the field of special integrated circuit manufacturing services.

In 2018, the world advanced company used Qromis substrate technology (referred to as QST TM) to develop the 0.35um 650V GaN-on-QST process of eight-inch QST substrate, which was completed in the first quarter of this year and successfully mass produced in the fourth quarter. At the same time, the world advanced company has cooperated with integrated component manufacturing (IDM) factory and IC design company.

Compared with silicon (Si) substrate, QST substrate has better thermal expansion coefficient (CTE) with gan epitaxial layer. While stacking Gallium nitride, it can also reduce warpage fragments, which is more conducive to mass production. The 0.35um 650V GaN-on-QST process of the world advanced company can cooperate with the company's existing 8-inch silicon wafer equipment in development and production to achieve the best production efficiency and yield. According to the system verification results of the client, the gallium nitride wafers provided by advanced companies in the world have reached the world's leading level of system efficiency for fast-charging products over 65W. In addition, based on the good heat dissipation characteristics of QST substrate, the gallium nitride wafers provided by advanced companies in the world have better heat dissipation performance in terms of the overall fast charging scheme.

CTOnews.com learned that Dr. Wei Jishi, Director of Operations of the World Advanced Company, said: "as the leading manufacturer of special integrated circuit manufacturing services, the world advanced company continues to refine the process technology to provide customers with the most cost-effective and complete solutions and high value-added services. Our 0.35um 650V GaN-on-QST process has the advantages of performance and reliability, not only providing customers with more optimized IC design options, but also helping to enhance the competitiveness of their products. "

The world's advanced company 0.35um 650V GaN-on-QST process not only provides 650V component selection, but also provides built-in electrostatic protection components (ESD), making it more convenient for customers to make design choices. In addition, the process not only has better reliability and reliability, but also aims at the scalability of higher voltage (more than 1000V). The world's advanced companies have also cooperated with some customers to meet their product needs.
