NORTH AMERICAN MANUFACTURERS POST $1.07 BILLION IN ORDERS.

North American-based manufacturers of semiconductor equipment posted $1.07 billion in orders in June 2005 (three-month average basis) and a book-to-bill ratio of 0.93 according to the June 2005 Book-to-Bill Report published today by SEMI. A book-to-bill of 0.93 means that $93 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in June 2005 was $1.07 billion. The bookings figure is 5.5 percent above the revised May 2005 level of $1.02 billion and 33 percent below the $1.61 billion in orders posted in June 2004.

The three-month average of worldwide billings in June 2005 was $1.15 billion. The billings figure is 4.9 percent below the revised May 2005 level of $1.21 billion and 33 percent below the June 2004 billings level of $1.50 billion.

"North American providers of new semiconductor manufacturing equipment continue to see stabilizing trends and a book-to-bill ratio that is trending toward parity," said Stanley T. Myers, president and CEO of SEMI. "While overall billings are below last year's levels, the current data reflects incremental improvement for front-end and especially final manufacturing equipment."

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.
