In accordance with Section 223 of the Trade Act of 1974, as
amended ("Act"), 19 U.S.C. § 2273, the Department of Labor
herein presents the results of an investigation regarding
certification of eligibility to apply for worker adjustment
assistance.
The group eligibility requirements for workers of a firm
under Section 222(a) of the Act, 19 U.S.C. § 2272(a), are
satisfied if the following criteria are met:
(1) a significant number or proportion of the
workers in such workers' firm have become totally or
partially separated, or are threatened to become
totally or partially separated;
(2)(B)(i)(I) there has been a shift by the workers'
firm to a foreign country in the production of
articles or supply of services like or directly
competitive with those produced/supplied by the
workers' firm; OR
(II) there has been an acquisition from a
foreign country by the workers' firm of
articles/services that are like or directly
competitive with those produced/supplied by
the workers' firm; AND
(ii) the shift/acquisition must have contributed
importantly to the workers' separation or
threat of separation.

The investigation was initiated in response to a petition
filed on January 25, 2018 by a state workforce official on
behalf of workers of Vishay Siliconix, Siliconix Mosfets
division, Santa Clara, California (Vishay Siliconix). The
workers of Vishay Siliconix is engaged in activities related to
the production of power mosfet wafers.
During the course of the investigation, information was
collected from the workers' firm and the petitioner.
Section 222(a)(1) has been met because a significant
number or proportion of the workers in such workers' firm have
become totally or partially separated, or are threatened to
become totally or partially separated.
Section 222(a)(2)(B) has been met because the workers'
firm has shifted to a foreign country the production of an
article like or directly competitive with the article produced
by the workers which contributed importantly to worker group
separations at Vishay Siliconix.
Conclusion
After careful review of the facts obtained in the
investigation, I determine that workers of Vishay Siliconix,
Siliconix Mosfets division, Santa Clara, California, who are
engaged in activities related to the production of power mosfet
wafers meet the worker group certification criteria under
Section 222(a) of the Act, 19 U.S.C. § 2272(a). In accordance
with Section 223 of the Act, 19 U.S.C. § 2273, I make the
following certification:
"All workers of Vishay Siliconix, Siliconix Mosfets
division, Santa Clara, California, who became totally or
partially separated from employment on or after January 24,
2017 through two years from the date of certification, and
all workers in the group threatened with total or partial
separation from employment on the date of certification
through two years from the date of certification, are
eligible to apply for adjustment assistance under Chapter 2
of Title II of the Trade Act of 1974, as amended."
