King Yuan Electronics (KYEC) and Sigurd Microelectronics have announced slides in November 2010 revenues from the previous month, while Ardentec saw November sales grow about 2% on month.

Affected by weakening demand for memory chips and LCD driver ICs, KYEC's November revenues dropped 5.2% sequentially to NT$1.1 billion (US$36 million), the monthly lowest since February.

KYEC accumulated NT$13.19 billion in revenues from January through November, up 40.1% from the same period of 2009.

Sigurd generated consolidated revenues of NT$392 million in November, down 0.1% on month and meeting the company's expectations. Consolidated sales for December are likely to drop by up to 10% sequentially, as sales contributed by its non-Taiwan based clients decrease on seasonality, according to the company.

Buoyed by continued strong demand for logic chips, Ardentec's November consolidated revenues increased slightly on month to NT$427 million. The company expects fourth-quarter sales to drop by a single-digit rate sequentially.
