SAN FRANCISCOŚNorth America-based semiconductor equipment manufacturers posted a book-to-bill ratio of 0.88 in December, up from a final book-to-bill of 0.83 in November, according to the fab tool vendor trade group SEMI.
December marked the third consecutive month of improving book-to-bill for North American tool vendors, following six consecutive months of declines.
Tool makers reported $1.16 billion worth of orders in December, based on a three-month rolling average, up 18 percent from November but down 26.7 percent compared to December 2010, SEMI said. The reported a three-month average of $1.32 billion worth of orders in December, up 11.8 percent from November and down 25.2 percent compared to December 2010, SEMI said.
"The December data reflects a further increase in bookings for semiconductor equipment," said Dan Tracy, senior director of industry research and statistics at SEMI, in a statement. "Recent capital spending announcements by leading device manufacturers indicate the potential for continued improvement in 2012.
The SEMI book-to-bill is a ratio of three-month moving averages of worldwide bookings and billings for North American-based semiconductor equipment manufacturers. A book-to-bill of 0.88 means that $88 worth of orders were received for every $100 of product billed for the month.
