Certification Regarding Eligibility
To Apply for Worker Adjustment Assistance

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(c) of the Act, 19 U.S.C. § 2272(c), can be
satisfied if the following criteria are met:
I. a significant number or proportion of the workers in
the workers' firm or an appropriate subdivision of the
firm have become totally or partially separated, or
are threatened to become totally or partially
separated;

II. the workers' firm is a Supplier or Downstream Producer
to a firm that employed a group of workers who
received a certification of eligibility under Section
222(a) of the Act, 19 U.S.C. § 2272(a), and such
supply or production is related to the article or
service that was the basis for such certification; and

III. either
(A) the workers' firm is a supplier and the component
parts it supplied to the firm described in paragraph
(2) accounted for at least 20 percent of the
production or sales of the workers' firm; or
(B) a loss of business by the workers' firm with the firm
described in paragraph (2) contributed importantly to
the workers' separation or threat of separation.

Section 222(d) of the Act, 19 U.S.C. § 2272(d), defines the
term "Supplier" as "a firm that produces and supplies directly
to another firm component parts for articles, or services used
in the production of articles or in the supply of services, as
the case may be, that were the basis for a certification of
eligibility under subsection (a) [of Section 222 of the Act] of
a group of workers employed by such other firm."
The investigation was initiated in response to a petition
filed on June 19, 2009 by a state agency representative on
behalf of workers of Mattson Technology, Inc., U.S. Field
Service Engineering Group, Fremont, California (Mattson). The
workers are engaged in activities related to the maintenance of
semiconductor wafer processing equipment. The worker group
includes on-site leased workers from Nstar Global Services, Inc.
The investigation revealed that workers of Mattson
Technology who are engaged in activities related to the supply
of maintenance services meet the criteria as Suppliers for
secondary worker certification.
Criterion I has been met because a significant proportion
of workers at the workers' firm have been separated or
threatened with separation during the relevant period.
Criterion II has been met because workers of Mattson
Technology supplied and sold maintenance services to a firm
that employed a worker group who is covered by an active
certification used in the production of semiconductor wafers.
Criterion III has been met because the services supplied
by Mattson for a firm that employed a worker group covered by
an active certification accounted for at least 20 percent of
the sales of the workers' firm.
Conclusion
After careful review of the facts obtained in the
investigation, I determine that workers of Mattson Technology,
Inc., U.S. Field Service Engineering Group, Fremont,
California, who are engaged in activities related to supply of
maintenance services, meet the worker group certification
criteria under Section 222(c) of the Act, 19 U.S.C. § 2272(c).
In accordance with Section 223 of the Act, 19 U.S.C. § 2273, I
make the following certification:



"All workers of Mattson Technology, Inc., U.S. Field
Service Engineering Group, including on-site leased
workers of Nstar Global Services, Inc., Fremont,
California, who became totally or partially separated from
employment on or after June 18, 2008, 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."
Signed in Washington, D.C., this 10th day of March, 2010
