reported lower-than-expected quarterly earnings Thursday and warned that things could get worse.

Taiwan Semiconductor also announced that it would cut capital spending to less than $2 billion from $2.6 billion amid falling demand. That news was weighing heavily on chip-equipment stocks in the U.S. in early trading.

shed 8% after being downgraded ahead of its earnings.

The losses were contributing to weakness in the


, which was off about 1.7% in early trading.

Chairman Morris Chang said corporate malfeasance in the U.S. had dented consumer confidence in the quarter and, as a result, he said the company's directors and supervisors would form an auditing committee with independent directors.

Mobile phones, digital cameras and networking equipment added support, however.

The company said it would show no revenue growth in the third quarter amid declining shipments and a 5% drop in average selling prices. It also added that falling demand along with rising capacity would cut its capacity utilization rate to just over 70% in the third quarter from 85% in the second quarter.
