Item 5.02. Election of Directors.

Effective January 24, 2008, the board of directors (the “Board”) of Rubicon Technology, Inc. (the “Company”) elected Raymond Spencer to fill an existing vacancy on the Company’s Board. The Board also appointed Mr. Spencer to serve on the Board’s compensation committee (the “Compensation Committee”), filling a vacancy created by Gordon Hunter’s resignation from the Compensation Committee. Mr. Spencer’s current term on the Board will expire at the Company’s 2008 annual meeting of stockholders. There is no arrangement or understanding between Mr. Spencer and any other person pursuant to which Mr. Spencer was elected as a director.

Mr. Spencer will receive the standard annual fees payable to all non-employee directors, which fees consist of an annual fee of $50,000 for service as a director and an annual fee of $2,500 for service to the Compensation Committee. The Company also intends to enter into an indemnification agreement with Mr. Spencer that is substantially similar to the form of indemnification agreement executed by other members of the Board. The Board has authorized a grant of 4,310 shares of restricted stock to Mr. Spencer, with an aggregate value of $100,000, based on the closing price of the Company’s stock on the NASDAQ Global Market on January 28, 2008.

On January 28, 2008, the Company issued a press release announcing Mr. Spencer’s election. A copy of the press release is attached hereto as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
