SCHEDULE TO

This Amendment No. 1 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO originally filed with the Securities and Exchange Commission (the “Commission”) on November 8, 2006 (the “Tender Offer Statement”), and relates to the offer by offer by Tegal to holders of outstanding options to purchase its common stock under the Eighth Amended and Restated 1998 Equity Participation Plan (the “Plan”) with an exercise price greater than or equal to $7.70, two times the closing price of a share of Tegal common stock on November 3, 2006 (“Eligible Options”). The Offer is for holders to cancel their Eligible Options in exchange for a lesser number of either (1) restricted stock units (“RSUs”) or (2) new options to purchase shares of Tegal’s common stock (“New Options”), issued under the Plan on the terms and conditions set forth in the Offer to Exchange Outstanding Options to Purchase Common Stock filed as Exhibit (a)(1)(A) to the Tender Offer Statement (the “Offer”).

The information contained in the Offer is expressly incorporated by reference into this Amendment, except that such information is hereby amended and supplemented to the extent specifically provided herein. This Amendment is intended to satisfy the reporting requirements of Rule 13e-4(c)(2) of the Securities Exchange Act of 1934, as amended.

ITEMS 1 through 11. 
 
Items 1 through 11 of the Tender Offer Statement, which incorporate by reference the information contained the Offer, a copy of which was filed with the original Tender Offer Statement as Exhibit (a)(1(A) , is hereby amended as follows:

 
1.
The fourth full paragraph on the front cover of the Offer has been revised to read as follows:
 
We are offering to exchange unexercised Eligible Options by determining the value of the Eligible Options as of November 3, 2006 using the Black-Scholes option pricing model (the “Dollar Value”). The Black-Scholes valuation model is a widely used model for calculating the value of derivative securities. You may elect whether to exchange your Eligible Options for either RSUs or New Options. The number of either RSUs or New Options that you will be granted in exchange for cancellation of your Eligible Options will be determined by the following formula: the Dollar Value of your Eligible Options will be reduced by ten percent (10%), then that reduced amount will be divided by the “fair market value” of a share of Company common stock. “Fair market value” for this purpose is the average closing price of a share of Company common stock as reported on the Nasdaq Capital Market for the ten trading-day period ending on the trading day that is two trading days before the Expiration Date. You may call Tegal at (800) 828-3425 to confirm the Dollar Value of your Eligible Options and to determine the number of New Options or RSUs you would be eligible to receive in the Option Exchange Program.
 
 
2.
The fifth full paragraph on the front cover of the Offer has been revised to read as follows:
 
As an example, if you have an Eligible Option grant representing the right to purchase 100 shares of common stock and you elect to exchange this Eligible Option for RSUs, you will receive RSUs on the Grant Date representing the right to receive the number of shares of Company common stock equal to the Dollar Value of your Eligible Option, reduced by 10%, and divided by the fair market value (the average closing price of a share of Company common stock as reported on the Nasdaq Capital Market for the ten trading-day period ending on the trading day that is two trading days before the Expiration Date).
 
 
3.
The second sentence in the last full paragraph on the front cover of the Offer has been revised to read as follows:
 
“On November 15, 2006, the closing price of our common stock as reported on the Nasdaq Capital Market was $4.60 per share.”
 
 
4.
Question 8 under the “Summary of Terms of the Offer” has been revised to read as follows:
 
Specific Questions About the Eligible Options to be Exchanged
 

 
Q8.
If I participate, how many RSUs or New Options will I receive?
 
Under this Offer, you may make an election to exchange your unexercised Eligible Options for a number of either RSUs or New Options to be granted in accordance with the following exchange formula:
 
Dollar Value of your Eligible Options (determined as of November 3, 2006 using the Black-Scholes  option pricing model),
 
Minus ten percent (10%),
 
Divided by the “fair market value” of a share of Company common stock.
 
“Fair market value” for this purpose is the average closing price of a share of Company common stock as reported on the Nasdaq Capital Market for the ten trading-day period ending on the trading day that is two trading days before the Expiration Date. If any fractional numbers result from the exchange formula calculation, RSU and New Option grants will be rounded down for any fractional option to the next whole share on a grant-by-grant basis.

 
5.
Question 33 under the “Summary of Terms of the Offer” has been revised to read as follows:
 
Q33.
Who can I talk to if I have questions about the Offer?
 
You may call Tegal at (800) 828-3425 to confirm the Dollar Value of your Eligible Options and to determine the number of New Options or RSUs you would be eligible to receive in the Offer. For additional assistance, please call Adam LaVigna @ 707-765-5656 or send an e-mail to alavigna@tegal.com. You should consult your personal outside advisor(s) if you have questions about your financial or tax situation.
 
 
6.
The fifth full paragraph in Section 1. “Number of Options; Expiration Date” has been revised to read as follows:
 
In this Offer, each Eligible Option grant may be exchanged for RSUs or New Options, as elected, to be granted in accordance with the following exchange formula:
 
Dollar Value of your Eligible Options (determined as of November 3, 2006 using the Black-Scholes  option pricing model),
 
Minus ten percent (10%),
 
Divided by the “fair market value” of a share of Company common stock.
 
“Fair market value” for this purpose is the average closing price of a share of Company common stock as reported on the Nasdaq Capital Market for the ten trading-day period ending on the trading day that is two trading days before the Expiration Date. If any fractional numbers result from the exchange formula calculation, RSU and New Option grants will be rounded down for any fractional option to the next whole share on a grant-by-grant basis.
 
 
7.
The sixth full paragraph in Section 1. “Number of Options; Expiration Date” has been revised to read as follows:
 
As an example, if you have an Eligible Option grant representing the right to purchase 100 shares of common stock and you elect to exchange this Eligible Option for RSUs, you will receive RSUs on the Grant Date representing the right to receive the number of shares of Company common stock equal to the Dollar Value of your Eligible Option, reduced by 10%, and divided by the fair market value (the average closing price of a share of Company common stock as reported on the Nasdaq Capital Market for the ten trading-day period ending on the trading day that is two trading days before the Expiration Date).
