North American Semiconductor Equipment Industry Posts November 2010 Book-to-Bill Ratio of 0.96

SAN JOSE, Calif. – December 16, 2010 – North America-based manufacturers of semiconductor equipment posted $1.51 billion in orders in November 2010 (three-month average basis) and a book-to-bill ratio of 0.96, according to the November 2010 Book-to-Bill Report published today by SEMI. A book-to-bill of 0.96 means that $96 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in November 2010 was $1.51 billion. The bookings figure is 5.3 percent lower than the final October 2010 level of $1.59 billion, and is 90.6 percent above the $791.8 million in orders posted in November 2009.

The three-month average of worldwide billings in November 2010 was $1.57 billion. The billings figure is down 3.4 percent from the final October 2010 level of $1.62 billion, and is 110.7 percent above the November 2009 billings level of $744.2 million.

“Following a historic growth period and 18 months of sequential growth, and in accordance with seasonal trends, sales of semiconductor equipment eased in November,” said Stanley T. Myers, president and CEO of SEMI. "This tracks the bookings trend which peaked in July.”

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. Billings and bookings figures are in millions of U.S. dollars.
