Posts September 2010 Book-To-Bill Ratio of 1.03

SAN JOSE, Calif. – October 21, 2010 – North America-based manufacturers of semiconductor equipment posted $1.62 billion in orders in September 2010 (three-month average basis) and a book-to-bill ratio of 1.03, according to the September 2010 Book-to-Bill Report published today by SEMI. A book-to-bill of 1.03 means that $103 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in September 2010 was $1.62 billion. The bookings figure is 11.0 percent lower than the final August 2010 level of $1.82 billion, and is 113.0 percent above the $758.9 million in orders posted in September 2009.

The three-month average of worldwide billings in September 2010 was $1.58 billion. The billings figure is up 1.3 percent from the final August 2010 level of $1.55 billion, and is 143.0 percent above the September 2009 billings level of $648.4 million.

"Total actual billings through September are up more than 70 percent compared to 2009, highlighting the strong industry recovery this year,” said Daniel Tracy, director of Industry Research & Statistics at SEMI. "Bookings rates, which increased sharply over the past year, have eased in August and September."

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.
