In a press conference last Thursday, TSMC Chairperson Morris Chang assured the investors that the recent disaster in Japan has had little impact on the supply chain of the semiconductor manufacturer, and its 20% target of revenue growth for this year remains unchanged.

According to TSMC Chairman Morris Chang, the effect of Japan's earthquake and tsunami on TSMC's supply chain has been negligible.

However, due to factors including inflation and the European debt crisis, this year's semiconductor industry growth forecast will be slashed from 7% to 4%.

At the same time, TSMC's target revenue growth rate for 2011 will remain 20%. UMC officials, meanwhile, said at their investor conference on Wednesday that its analysts are forecasting this year's worldwide semiconductor production growth rate at closer to 5% than 10% due to the earthquake in Japan.

SPIL, which also held an investor conference on Wednesday, forecasted its second quarter revenues at 3% to 7% and expressed optimism for the technology industry's performance in the second half of the year.

Factors including the restoration of the overall supply chain and the European sovereign debt crisis will likely determine how the industry performs this year.
