RE: Amtech Systems, Inc.—Registration
Statement on Form S-8 (2007 Employee Stock Incentive Plan)
Ladies and
Gentlemen:
We have acted as counsel to Amtech Systems,
Inc. an Arizona corporation (the “Company”), in connection with its registration
statement on Form S-8 (the “Registration Statement”) relating to the registration under the
Securities Act of 1933, as amended (the “Act”), of 900,000 shares (the “Shares”) of its common stock, $.01 par value per
share (“Common Stock”), issuable pursuant to the Company’s 2007
Employee Stock Incentive Plan, as amended through March 11, 2010. At the
Company’s annual meeting of stockholders held on March 11, 2010, the
stockholders approved an amendment to increase by 900,000 the number of shares
issuable pursuant to the Plan. Accordingly, the Registration Statement relates
to the Shares, which are in addition to the 500,000 shares of Common Stock
previously authorized for issuance under the Plan, and in respect of which the
Company filed a registration statement on Form S-8 (File No. 333-145454) filed
with the Securities and Exchange Commission (the “Commission”) on August 15, 2007.
In connection with the Registration Statement,
we have examined such documents, corporate records and other instruments and
undertaken such further inquiry as we have deemed necessary or appropriate for
purposes of this opinion, including, but not limited to, examination of the
Registration Statement and the Certificate of Incorporation and Bylaws of the
Company, including all amendments thereto. In our examination, we have assumed
the genuineness of all signatures, the legal capacity of all natural persons,
the accuracy and completeness of all documents submitted to us, the authenticity
of all original documents, and the conformity to authentic original documents of
all documents submitted to us as copies (including telecopies). This opinion
letter is given, and all statements herein are made, in the context of the
foregoing.
Based upon, subject to and limited by the
foregoing, we are of the opinion that (i) the Shares when sold, will be duly
authorized, validly issued, fully paid and nonassessable.
We hereby consent to the use of this opinion
as an exhibit to the Registration Statement. In giving this consent, we do not
thereby admit that we are “experts” within the meaning of the Act, nor do we
admit that we are within the category of persons whose consent is required under
Section 7 of the Act or under the rules and regulations of the
Commission.
We do not express an opinion on any matters
other than those expressly set forth in this letter.
Very truly
yours,
