North American Semiconductor Equipment Industry Posts July 2008 Book-to-Bill Ratio of 0.83

SAN JOSE, CA–(EMWNews – August 19, 2008) – North America-based manufacturers of

semiconductor equipment posted $905 million in orders in July 2008

(three-month average basis) and a book-to-bill ratio of 0.83 according to

the July 2008 Book-to-Bill Report published today by SEMI. A book-to-bill

of 0.83 means that $83 worth of orders were received for every $100 of

product billed for the month.

The three-month average of worldwide bookings in July 2008 was $905

million. The bookings figure is three percent less than the final June 2008

level of $934 million, and about 36 percent less than the $1.41 billion in

orders posted in July 2007.

The three-month average of worldwide billings in July 2008 was $1.09

billion. The billings figure is about six percent less than the final June

2008 level of $1.16 billion, and about 36 percent less than the July 2007

billings level of $1.69 billion.

“Orders for semiconductor equipment continue reflect the pronounced cutback

in capital expenditures this year and are at the lowest levels since

November of 2003,” said Daniel Tracy, senior director of Industry Research

and Statistics at SEMI. “While chip-makers remain attentive to cost

controls, this remains a highly cyclic industry. Factory utilization

levels, unit demand growth and planned fab projects suggest that new

investment activity will resume in 2009.”

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.
