NA Semiconductor Equipment Industry Posts Book-to-Bill Ratio of 1.00

North American-based manufacturers of semiconductor equipment posted $1.62 billion in orders in September 2006 (three-month average basis) and a book-to-bill ratio of 1.00 according to the September 2006 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 September 2006 was $1.62 billion. The bookings figure is six percent below the final August 2006 level of $1.73 billion and almost 65 percent above the $984 million in orders posted in September 2005.

The three-month average of worldwide billings in September 2006 was $1.63 billion. The billings figure is almost seven percent below the final August 2006 level of $1.74 billion and almost 50 percent above the September 2005 billings level of $1.09 billion.

“Bookings for the North American semiconductor equipment manufacturers declined in September as the current equipment cycle slows down,” said Dan P. Tracy, senior director of Industry Research and Statistics at SEMI. “Overall performance for the year, however, remains on track to become the second strongest year for equipment spending in the semiconductor industry.”

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.

  Billings (Three-month avg.) Bookings (Three-month avg.) Book-to-Bill
April 2006 1,441.4 1,604.4 1.11
May 2006 1,452.6 1,619.0 1.11
June 2006 1,557.4 1,782.3 1.14
July 2006 1,637.9 1,734.6 1.06
August 2006 (final) 1,742.8 1,729.7 0.99
September 2006 (prelim.) 1,627.4 1,624.0 1.00

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 October 2006 SEMI Book-to-Bill Report is scheduled for publication on November 16, 2006; 3:00 p.m. PDT (subject to change).

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