Worldwide silicon wafer revenues declined by 13% in 2013 compared to 2012, while silicon wafer area shipments increased 0.4%, according to SEMI.

Silicon wafer area shipments in 2013 totaled 9.067 billion square inches, up slightly from the 9.031 billion square inches shipped during 2012. Revenues totaled US$7.5 billion, compared to the US$8.7 billion posted in 2012.

“Annual semiconductor silicon shipment levels have remained essentially flat for the past three years,” said Hiroshi Sumiya, chairman of SEMI SMG and general manager of the corporate planning department of Shin-Etsu Handotai. “However, industry revenues have declined significantly for the past two years.”
