SAN JOSE, Calif. – June 19, 2007
– North American-based manufacturers of semiconductor equipment posted $1.67 billion in orders in May 2007 (three-month average basis) and a book-to-bill ratio of 1.00 according to the May 2007 Book-to-Bill Report published today by SEMI. A book-to-bill of 1.00 means that $100 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in May 2007 was $1.67 billion. The bookings figure is about six percent greater than the final April 2007 level of $1.57 billion and about three percent greater than the $1.62 billion in orders posted in May 2006.

The three-month average of worldwide billings in May 2007 was $1.67 billion. The billings figure is about five percent greater than the final April 2007 level of $1.59 billion and 15 percent greater than the May 2006 billings level of $1.45 billion.

"Bookings and billings remain at levels above a year ago, and there is relative equilibrium in the book-to-bill ratio, which has remained very near parity for half of a year," said Stanley T. Myers, president and CEO of SEMI. "We are surveying member companies and will issue a new consensus forecast outlook for capital equipment next month during SEMICON West."

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.

The June 2007 SEMI Book-to-Bill Report is scheduled for publication on July 17, 2007; 3:00 p.m. PDT (subject to change).

Independently from SEMI, The Semiconductor Equipment Association of Japan (SEAJ) releases its June Book-to-Bill Report on approximately the same date. The SEAJ Book-to-Bill Report tracks billings and bookings worldwide of Japanese-headquartered semiconductor equipment manufacturers. For more information on the SEAJ data, visit
