On June 17, 1999, SEMATECH announced that it was integrating the four companies in its International SEMATECH subsidiary into the full consortium and would operate under the name International Sematech. It was an organizational and membership change—not the creation of a separate consortium from scratch—and access to research programs was scheduled to expand in stages.
What SEMATECH announced on June 17, 1999
SEMATECH announced in Austin, Texas, that its membership would expand to include the four companies participating through International SEMATECH: Hyundai Electronics Industries of South Korea, Taiwan Semiconductor Manufacturing Co. (TSMC), Infineon Technologies of Germany, and Philips Semiconductors of the Netherlands. The unified organization would be known as International Sematech. EE Times reported the announcement on June 18, 1999; its account describes the change as an integration of the subsidiary’s members into the parent consortium. (EE Times, June 18, 1999)
The distinction matters: the four companies were not wholly new to SEMATECH’s international work. They had been participating in International SEMATECH programs since April 1998. What changed in June 1999 was their place in the organization: the subsidiary and the broader consortium were being brought together under one international identity.
Why the organization widened its membership
SEMATECH was formed in 1987 as a U.S. government–industry partnership intended to strengthen American semiconductor manufacturing, particularly amid competition from Japan. The consortium conducted advanced manufacturing research and sought to transfer useful technology to its member companies. The U.S. Government Accountability Office describes its federal role and original objectives in its 1991 account (GAO: SEMATECH’s formation and objectives); DARPA also summarizes its origins and later development (DARPA: SEMATECH timeline).

By the late 1990s, the industry’s manufacturing and research challenges crossed national boundaries. Moving to larger wafers and developing advanced lithography and manufacturing processes required substantial technical effort and investment. SEMATECH’s rationale, as described in contemporary coverage, was that companies in different regions could pool expertise and resources and share the benefits and costs of tackling difficult problems. The Japanese competitive pressure that helped prompt the original U.S.-focused initiative had also changed; contemporary industry commentary framed internationalization as a response to that shift, not as the sole reason for it. (Electronics Weekly, June 1999)
The organization’s funding model had evolved too. DARPA says SEMATECH was operating without annual government funding by 1997. That milestone does not mean every form of government involvement disappeared; it does show that the 1999 expansion came after the consortium had moved beyond its initial annual federal funding arrangement.

What the four companies were working on—and when access expanded
Before the June announcement, the four companies’ International SEMATECH participation included 300-millimeter wafer manufacturing, lithography, environment, safety and health programs, and standards. Membership integration did not mean that every technical program opened to them on the announcement date. The contemporary report described a staged schedule:
| Timing | Participation described in the June 1999 report |
|---|---|
| Since April 1998 | Work through International SEMATECH on 300-millimeter wafers, lithography, environment/safety/health, and standards |
| During 1999 | Scheduled entry into the Interconnect Division |
| In 2000 | Scheduled participation in remaining technical programs, including Front-End Processes and Advanced Technology |
This sequence shows the operational significance of the merger: the companies were moving from participation through a separate international subsidiary toward access to the larger consortium’s technical program, with the rollout phased rather than instantaneous. The dates and program areas come from EE Times’ contemporary account.

Membership snapshot from the June 1999 announcement
The contemporary report listed the following companies in the broader consortium. This is a dated roster, not a permanent membership list:
| Companies integrated from International SEMATECH | Other companies listed in the June 1999 report |
|---|---|
| Hyundai Electronics Industries (South Korea) TSMC (Taiwan) Infineon Technologies (Germany) Philips Semiconductors (Netherlands) |
Advanced Micro Devices Compaq Computer Conexant Hewlett-Packard Intel IBM Lucent Technologies Motorola STMicroelectronics Texas Instruments |
These are the corporate names used in the 1999 coverage. Hyundai Electronics Industries was later associated with the name Hynix; Philips Semiconductors was part of Royal Philips Electronics. Company identities and consortium membership subsequently changed. Later coverage described a different roster and referred to five non-U.S. members, which is a later snapshot—not a replacement for the four companies named in the June 1999 announcement.

Why the change matters in SEMATECH’s history
The June 1999 announcement marked a transition from a U.S.-centered, federally supported manufacturing initiative with an international subsidiary to a unified consortium with an international membership model. It connected the consortium’s original industrial-policy purpose—improving manufacturing capability through shared research—to an industry in which technical challenges and capabilities were increasingly global.
The name change alone understates the event. The consequential step was integrating the subsidiary’s members and programs into the parent organization, while expanding participation according to a defined schedule. SEMATECH’s earlier public-private structure and technology-transfer goals are documented by the GAO and the GAO’s testimony on its startup and technology transfer.
