Week In Review: Manufacturing, Test

Amkor expands; SiC; 3nm analytics, AI center; DRAM downturn.


Amkor plans to build a packaging plant in Bac Ninh, Vietnam. The first phase of the new factory will focus on providing system-in-package (SiP) assembly and test services for customers. The investment for the first phase of the facility is estimated to be between $200 million and $250 million.

“This is a strategic, long-term investment in geographical diversification and factory capacity expansion, supporting the company’s commitment to reliable supply chain solutions for our customers. Factory utilization is high, particularly at our advanced packaging sites, and we expect the strong market demand for assembly and test solutions to continue. Investing in Bac Ninh expands our manufacturing footprint in support of customer need for an alternative cost-competitive supply chain solution for advanced SiP – and for other packaging solutions in the future,” said Giel Rutten, Amkor’s president and chief executive.

“The Bac Ninh site, located in the Yen Phong 2C Industrial Park, is approximately 230,000 square meters, or about 57 acres, providing us with room for the first phase and future expansion,” added Rutten. “Construction for the first phase of clean room space, which is currently estimated at 20,000 square meters, is expected to commence in 2022, and high-volume manufacturing is expected to begin by the second half of 2023, based on projected customer product cycles.”

Qorvo has entered the silicon carbide (SiC) market by acquiring United Silicon Carbide (UnitedSiC), a fabless supplier of SiC power semiconductors. The acquisition expands Qorvo’s reach into the fast-growing markets for electric vehicles, industrial power, circuit protection, renewables and data center power supplies. United Silicon Carbide will become part of Qorvo’s Infrastructure & Defense Products business. Chris Dries, formerly United Silicon Carbide’s president and CEO, is now general manager of Qorvo’s Power Device Solutions unit.


The Army Research Office and the Army Research Laboratory will contribute more than $5 million in funding for a SiC fabrication facility at the University of Arkansas.

The grants — $4.5 million from the Army Research Office and $900,000 from the Army Research Laboratory — come on the heels of an $18 million grant from the National Science Foundation to fund construction and operation of the national fabrication facility. The Army Research Office grant will be used for equipment, and the Army Research Laboratory grant for student and staff compensation, tuition and materials for supporting collaborative research activities.

The facility will develop prototype SiC devices. It will provide domestic opportunities for prototyping, proof-of-principle demonstrations and device design. It will be the first open-access fabrication facility of its kind in the U.S., meaning its facilities and services will be available to external researchers.


Taiwan foundry vendor Vanguard International Semiconductor has increased its capital spending amid booming chip demand, according to a report from the Taipei Times.

Tower Semiconductor and Anello Photonics, a developer of so-called Silicon Photonic Optical Gyroscope technology, have announced a strategic partnership for a new low-loss silicon optical waveguide technology and manufacturing process.

SkyWater has announced that its Minnesota fab has completed certification to AS9100, the standardized quality management system for organizations that design, develop or provide aviation, space and defense products and services. The designation is the result of passing stringent audit requirements and evaluations of the facility’s manufacturing processes.

Fab tools
Data analytics specialist proteanTecs has announced that its Universal Chip Telemetry (UCT) monitoring technology now supports TSMC’s 3nm process. The data analytics company has developed enterprise cloud and edge monitoring software based on deep data. The novel data is generated by on-chip monitoring IPs that are built for analytics. Once deployed in the field, service providers can be alerted on faults before failures, reduce maintenance costs and RMAs.

“This announcement marks yet another milestone achieved in our long-term collaboration with TSMC to bring scale and optimization to the industry, with visibility into the 3nm generation of silicon process nodes, from production to lifetime operation. Chip makers, system manufacturers, and service providers gain the assurance they need to bring robust and competitive products to market,” commented Evelyn Landman, CTO of proteanTecs.


KLA has announced the opening of two facilities in Chennai, India. KLA’s Artificial Intelligence-Advanced Computing Lab (AI-ACL)—operated in partnership with the Indian Institute of Technology (IIT) Madras—will serve as a center of excellence for AI-focused research and development.
