Scott ("Reporting Person") on May 2, 2005 (the "Schedule 13D"), as amended May 15, 2006, June 27, 2006 and November 27, 2006 with respect to shares of the Common Stock, $.01 par value ("Common Stock"), of Amtech Systems, Inc., an Arizona corporation (the "Issuer"). Capitalized terms used but not defined herein shall have the respective meanings ascribed to such terms in the Schedule 13D. The following Items are hereby amended as follows: Item 3 is hereby amended and restated to read as follows: Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. The Reporting Person has used personal funds of approximately $2,455,231.40 to acquire the 487,443 shares of Common Stock owned by the Reporting Person (including funds to acquire shares of Series A Preferred which have been converted into Common Stock). The shares were purchased by Amtech Investments, LLC, an entity controlled by the Reporting Person. Item 4 is hereby amended to add the following: On December 26, 2006, an affiliate of the Reporting Person delivered a letter to the President and Chief Executive Officer of the Issuer in which it questions the Issuer's intention to raise $15 million in a public offering of common stock (the "Offering"). The letter states that while exploiting significant opportunities in the solar industry may require additional working capital, it is not in the best interest of the existing stockholders to undertake the Offering, that relative to both comparable companies and intrinsic value, the Offering significantly undervalues the Issuer and that should the Issuer proceed as planned, significant value will be transferred from existing stockholders to stockholders participating in the Offering. The letter requests that the Issuer immediately withdraw the Form S-1 registering the Offering and terminate the engagement with its financial advisor. The letter states that unless the Issuer can convince the Reporting Person that the Offering is in the best interests of the stockholders or withdraws the Offering, the Reporting Person's only option will be to take action to call a Special Meeting of Stockholders to seek the votes necessary to change the composition of the Board of Directors in a manner that will protect the interests of the stockholders. A copy of the letter is attached hereto and incorporated herein by reference. The Reporting Person reserves the right to take any and all other action required to protect its investment in the Issuer including nominating directors at an annual meeting. Item 5 is hereby amended and restated to read as follows: Item 5.

Letter from Amtech Investments, LLC to the President and 7-8 Chief Executive Officer of Amtech Systems, Inc., dated December 26, 2006. - ------------------------- -------------------- CUSIP No. 032332-50-4 13D Page 7 of 8 Pages - ------------------------- -------------------- Exhibit 2 December 26, 2006 Mr. JS Whang President, Chief Executive Officer Amtech Systems, Inc. 131 South Clark Drive Tempe, AZ 85281 Dear JS: Richard L. Scott Investments, LLC ("RLSI"), through affiliates, beneficially owns over 14% of the outstanding shares of common stock of Amtech Systems, Inc. (the "Company"). As a former member of the Company's Board of Directors and a supportive shareholder of actions taken by the Company for almost two years, I am compelled to present my perspective regarding the Company's intent to raise $15MM in a public offering of common stock (the "Offering"). We invested in the Company due to the quality of the Company's management team, the strength of the Company's brands, the competitive positioning the Company enjoys in its industry, the attractive opportunities that we see available to the Company (particularly in the solar industry) and the fact that Amtech's stock trades at what we believe to be a low multiple of both revenues and EBITDA/Cash Flow compared to the intrinsic value of the Company. This remains applicable despite the recent increase in the Company's stock price after reporting your outstanding 4th quarter results and providing positive forward-looking comments on the conference call. As evidenced by your liquid balance sheet, capacity to borrow, and healthy order trends and backlog, the Company is well-positioned to pursue many of the opportunities that are available to it. I understand that exploiting the significant opportunities in the solar industry may require additional working capital, however, it is not in the best interest of the Company or its existing stockholders to undertake this equity offering. On December 19th, I signed a Non-Disclosure Agreement so that we could discuss the Company's proposed Offering. After speaking with your investment bankers, C.E. Unterberg, Towbin, I communicated to you, Brad Anderson, the Company's CFO, and Larry Firestone, a member of the Company's Board of Directors that the offering was a mistake because (a) you have not demonstrated the need for the new capital based on the strength of your existing balance sheet, (b) you have not shown any projected return on the moneys to be raised that would cause this Offering to not be significantly dilutive to your existing stockholders and (c) I do not believe the Company should be raising capital in the manner it is pursuing. At approximately 4pm on December 21st, just prior to announcing the Company's year-end results, you informed me that despite my objections, the Company had decided to proceed with the Offering and planned to imminently file a Form S-1. Based upon publicly-available information and my understanding of fees typically paid for investment banking services, it appears that the Company will be issuing new shares equal to approximately 60% of its' existing outstanding common shares at a valuation (as measured by Enterprise Value - taking into account the Company's cash and debt balances) that will likely represent: o ~35% my estimate of '07 Revenues - ------------------------- -------------------- CUSIP No. 032332-50-4 13D Page 8 of 8 Pages - ------------------------- -------------------- o ~4.5 times my estimate of '07 EBITDA Since the Company has minimal capital expenditure requirements, I believe that EBITDA is a reasonable proxy for operating cash flow. In addition, it is my understanding the Company has over $6.4MM in cash on its balance sheet and $3.3MM in bank financing available. It is my view that relative to both comparable companies and intrinsic value, the Offering significantly undervalues the Company and that should it proceed as planned, significant value will be transferred from existing shareholders, to shareholders participating in the Offering itself. A comparison of the trading activity in ASYS stock after the close of market hours on December 21st with that observed on December 22nd, the morning the proposed Offering was announced, seems to substantiate this view. Shareholders would be better served by waiting to raise capital until such time as the Company has a more defined use of the capital and at such time pursuing the least dilutive means to raise capital including utilizing existing bank and other debt financing alternatives. As such, we respectfully request that you immediately withdraw your S-1 registration and terminate your engagement with C.E. Unterberg, Tobin. While I am not advocating a sale of the Company at this time, as an alternative to the proposed significantly dilutive capital raise, I believe that the Company could be sold to a strategic buyer on terms that will result in appreciably more value for existing shareholders. As shareholders of Amtech Systems, Inc., we are fortunate to be invested in a company that is performing well, as evidenced by your recent operating results, order trends and backlog. Additionally, it is clear to us that the Company has bright prospects for growth, particularly in the solar industry. We are supportive of reasonable efforts to pursue such opportunities, but disagree with the Company's plans for raising capital without a more defined return on such capital. If you cannot convince us that the proposed Offering is in all shareholders best interest or fail to withdraw your S-1 registration, our only option will be to call a Special Meeting of Shareholders to seek the votes necessary to change the composition of the Company's Board of Directors in a manner that we believe would more closely protect the interests of existing shareholders. We hope that such actions will be unnecessary and that we can continue to work together in the best interests of the Company's stockholders. We remain thankful for your hard work and the positive fruits of your efforts. Unfortunately, we believe the proposed Offering is unfair to existing shareholders. Respectfully, Robert Averick Managing Director
