ITEM 1. SECURITY AND ISSUER. This statement on Schedule 13D relates to the common stock of Applied Science and Technology, Inc., a Delaware corporation ("ASTeX" or "Issuer"). The principal executive offices of ASTeX are located at 90 Industrial Way, Wilmington, Massachusetts 01887. ITEM 2. IDENTITY AND BACKGROUND. The name of the corporation filing this statement is MKS Instruments, Inc., a Massachusetts corporation ("MKS"). MKS's principal business is to supply gas measurement, control and analysis products used in semiconductor and other advanced thin-film manufacturing processes. The address of the principal executive offices of MKS is Six Shattuck Road, Andover, Massachusetts 01810. Set forth on Schedule A is the name, residence or business address, present principal occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted and citizenship of each of MKS's directors and executive officers, as of the date hereof. Neither MKS nor, to MKS's best knowledge, any person named on Schedule A hereto is required to disclose legal proceedings pursuant to Items 2(d) or 2(e). ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Pursuant to an Agreement and Plan of Merger, dated as of October 2, 2000 (the "Merger Agreement"), among MKS, Mango Subsidiary Corp., a Delaware corporation and a wholly owned subsidiary of MKS ("Merger Sub"), and ASTeX and, subject to the conditions set forth therein (including approval by stockholders of ASTeX and MKS), Merger Sub will merge with and into ASTeX and ASTeX will become a wholly owned subsidiary of MKS (such events constituting the "Merger"). Once the Merger is consummated, Merger Sub will cease to exist as a corporation and all of the business, assets, liabilities and obligations of Merger Sub will be merged into ASTeX with ASTeX remaining as the surviving corporation (the "Surviving Corporation"). As a result of the Merger, each outstanding share of ASTeX Common Stock, other than shares owned by MKS, will be converted into 0.7669 of a share (the "Exchange Ratio") of MKS Common Stock, and each outstanding option to purchase ASTeX Common Stock will be assumed by MKS. The foregoing summary of the Merger is qualified in its entirety by reference to the copy of the Merger Agreement included as Exhibit 1 to this Schedule 13D and incorporated herein in its entirety by this reference. ITEM 4. PURPOSE OF TRANSACTION. (a)-(b) As described in Item 3 above, this statement is related to the Merger of Merger Sub with and into ASTeX in a statutory merger pursuant to the Delaware General Corporation Law. At the effective time of the Merger, the separate existence of Merger Sub will cease to exist and ASTeX will continue as the Surviving Corporation and as a wholly owned subsidiary of MKS. Holders of outstanding ASTeX Common Stock will 4 CUSIP NO. 038236105 13D PAGE 4 OF 8 receive, in exchange for each share of ASTeX Common Stock held by them, 0.7669 of a share of MKS Common Stock. MKS will assume ASTeX's outstanding options. As an inducement to MKS to enter into the Merger Agreement, each of the individuals and the entities set forth on Schedule B, each a stockholder of ASTeX (collectively, the "Stockholders"), has executed a Stockholder Agreement, dated as of October 2, 2000, with MKS (the "Stockholder Agreement"), and, by doing so, has irrevocably appointed MKS as such stockholder's lawful attorney and proxy. Such proxy gives MKS the limited right to vote each of the 854,523 shares of ASTeX Common Stock beneficially owned by the Stockholders with respect to the adoption and approval of the Merger Agreement and the Merger. The shared voting power with the Stockholders relates to the same 854,523 shares of Issuer Common Stock (the "Shares"). The foregoing summary of the Stockholder Agreement is qualified in its entirety by reference to the copy of the Stockholder Agreement included as Exhibit 2 to this Schedule 13D and incorporated herein in its entirety by reference. In exercising its right to vote the Shares as lawful attorney and proxy of the Stockholders, MKS (or any nominee of MKS) will be limited, at every ASTeX stockholders meeting and every written consent in lieu of such meeting, to vote the shares in favor of approval of the Merger and the Merger Agreement. The Stockholders may vote the Shares on all other matters. The Stockholder Agreement terminates upon the earlier to occur of (i) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement or (ii) the date of termination of the Merger Agreement. (c) Not applicable. (d) It is anticipated that, upon consummation of the Merger, the directors of the Surviving Corporation shall be the current directors of Merger Sub. It is anticipated that the initial officers of the Surviving Corporation shall be the officers of Merger Sub, until their respective successors are duly elected or appointed and qualified. (e) Other than as a result of the Merger described in Item 3 above, not applicable. (f) Not applicable. (g) Upon consummation of the Merger, the Certificate of Incorporation of the Merger Sub, as in effect immediately prior to the Merger, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by the Delaware Law and such Certificate of Incorporation. Upon consummation of the Merger, the By-laws of the Merger Sub, as in effect immediately prior to the Merger, shall be the By-laws of the Surviving Corporation until thereafter amended. In addition, the Merger Agreement may have the effect of impeding the acquisition of control of Issuer by any person other than MKS. ASTeX will pay MKS a termination fee of $9,075,000 if ASTeX enters into an alternative transaction in which any person other than MKS or its affiliates acquires more than 20% of ASTeX's outstanding shares. (h)-(i) If the Merger is consummated as planned, the ASTeX Common Stock will be deregistered under the Act and delisted from the Nasdaq National Market. (j) Other than as described above, MKS currently has no plan or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D (although MKS reserves the right to develop such plans). ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. 5 CUSIP NO. 038236105 13D PAGE 5 OF 8 (a)-(b) In addition to the 52,500 shares of common stock for which MKS has sole voting power and sole dispositive power, as a result of the Stockholder Agreement, MKS may be deemed to be the beneficial owner of an additional 854,523 shares of Issuer Common Stock. Such Issuer Common Stock constitutes approximately 5.9% of the issued and outstanding shares of Issuer Common Stock. Schedule B sets forth the applicable information required by Item 2 with respect to each of the Stockholders with whom the power to vote is shared. (c)-(e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. John R. Bertucci, the Chairman and Chief Executive Officer of MKS, also serves as a director of ASTeX. Other than the Merger Agreement and the Stockholder Agreement, to the best knowledge of MKS, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the persons or entities listed in Item 2 and between such person or entity and any person or entity with respect to any securities of ASTeX, including but not limited to transfer of voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS. The following documents are filed as exhibits: 1. Agreement and Plan of Merger, dated as of October 2, 2000, by and among MKS, Merger Sub and ASTeX. 2. Stockholder Agreement, dated as of October 2, 2000, by and among MKS and each of the Stockholders. 6 CUSIP NO. 038236105 13D PAGE 6 OF 8 SIGNATURE After reasonable inquiry and to the best of my knowledge and belief, I hereby certify that the information set forth in this statement is true, complete and correct.
