Semiconductor Equipment Records Book-To-Bill Ratio of 1.06

North American-based manufacturers of semiconductor equipment posted $1.75 billion in orders in July 2006 (three-month average basis) and a book-to-bill ratio of 1.06 according to the July 2006 Book-to-Bill Report published today by SEMI. A book-to-bill of 1.06 means that $106 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in July 2006 was $1.75 billion. The bookings figure is about two percent lower than the final June 2006 level of $1.78 billion and over 73 percent higher than the $1.01 billion in orders posted in July 2005.

The three-month average of worldwide billings in July 2006 was $1.65 billion. The billings figure is almost six percent above the final June 2006 level of $1.56 billion and almost 53 percent above the July 2005 billings level of $1.08 billion.

“Billings for North American equipment manufacturers are at their highest level since April of 2001, while bookings decreased slightly,” said Stanley T. Myers, president and CEO of SEMI. “Even with a slight bookings slowdown, the worldwide equipment market is still on track to grow about 20 percent in 2006.”

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 data contained in this release was compiled by David Powell, Inc., an independent financial services firm, without audit, from data submitted directly by the participants. SEMI and David Powell, Inc. assume no responsibility for the accuracy of the underlying data.

The data are contained in a monthly Book-to-Bill Report published by SEMI. The report tracks billings and bookings worldwide of North American-headquartered manufacturers of equipment used to manufacture semiconductor devices, not billings and bookings of the chips themselves.

SEMI is a global industry association serving companies that provide equipment, materials and services used to manufacture semiconductors, displays, nano-scaled structures, micro-electromechanical systems (MEMS) and related technologies. SEMI maintains offices in Austin, Beijing, Brussels, Hsinchu, Moscow, San Jose (Calif.), Seoul, Shanghai, Singapore, Tokyo and Washington, D.C.

The August 2006 SEMI Book-to-Bill Report is scheduled for publication on September 19, 2006; 3:00 p.m. PDT (subject to change).

Independently from SEMI, The Semiconductor Equipment Association of Japan (SEAJ) releases its April 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.
