North American Semiconductor Equipment Industry Posts May 2010 Book-To-Bill Ratio of 1.12

SAN JOSE, Calif. – June 17, 2010 – North America-based manufacturers of semiconductor equipment posted $1.48 billion in orders in May 2010 (three-month average basis) and a book-to-bill ratio of 1.12, according to the May 2010 Book-to-Bill Report published today by SEMI. A book-to-bill of 1.12 means that $112 worth of orders was received for every $100 of product billed for the month.

The three-month average of worldwide bookings in May 2010 was $1.48 billion. The bookings figure is up 2.8 percent from the final April 2010 level of $1.44 billion, and is 415.3 percent above the $287.8 million in orders posted in May 2009.

The three-month average of worldwide billings in May 2010 was $1.32 billion. The billings figure is up 3.1 percent from the final April 2010 level of $1.28 billion, and is 236.0 percent above the May 2009 billings level of $392.6 million.

"Orders have increased for 14 consecutive months, commensurate with the turnaround in the market and the increase in announced capital spending plans," said Stanley T. Myers, president and CEO of SEMI. "SEMI members throughout the supply chain are working hard to fulfill customer orders and meet this rising demand.”

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.
