The deal is expected to close during the first quarter of 2007. Shares of Therma-Wave were trading up 36 cents to $1.61, while shares of KLA-Tencor were adding 75 cents to $50.90.

Syntax-Brillian ( BRLC) rose 1% after the maker of high-definition televisions estimated fourth-quarter revenue well above Wall Street's expectation. The company expects to post revenue of more than $240 million, while analysts' average forecast called for revenue of $190.8 million. The company also said that gross margins would be in the top half of its previously projected range of 15% to 17%. Shares were trading up 11 cents to $10.85.

Shares of Nu Horizons Electronics ( NUHC) slid 7% after the electronic-components distributor posted disappointing third-quarter results. For the period ended Nov. 30, the company earned $2.4 million, or 13 cents a share, on revenue of $186.1 million. Analysts polled by Thomson First Call expected earnings of 18 cents a share and revenue of $193.8 million. A year earlier, Nu Horizons earned $1.5 million, or 8 cents a share, on revenue of $147.5 million.

Despite the big year-year-over jump in sales, sequential sales were down. Nu Horizons said the decline related to "a substantial customer-specific decrease" in its systems business. It also blamed the shortfall on "market weakness related to some end customer and manufacturing channel inventory builds." Shares were trading down 68 cents to $9.52.

Shares of Tellabs ( TLAB) fell 3% after the telecom equipment maker warned that fourth-quarter earnings would be below expectations. The company sees adjusted earnings of 10 cents to 12 cents a share, compared with analysts' forecast of 14 cents. Tellabs lowered its revenue estimate to $455 million to $470 million from a prior range of $525 million to $550 million. Analysts project revenue of $534.2 million.

"These preliminary estimates were driven by lower than expected revenue from some large North American customers, an unfavorable shift in product mix, revenue deferrals related to a new product launch, and a lower effective tax rate," the company said. Shares were down 36 cents to $10.36.
