North American Semiconductor Equipment Industry Posts June 2006 Book-to-Bill Ratio of 1.14

SAN JOSE, Calif., July 20 /PRNewswire/ -- North American-based manufacturers of semiconductor equipment posted $1.75 billion in orders in June 2006 (three-month average basis) and a book-to-bill ratio of 1.14 according to the June 2006 Book-to-Bill Report published today by SEMI. A book-to-bill of 1.14 means that $114 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in June 2006 was $1.75 billion. The bookings figure is about eight percent higher than the final May 2006 level of $1.62 billion and over 68 percent higher than the $1.04 billion in orders posted in June 2005.

The three-month average of worldwide billings in June 2006 was $1.53 billion. The billings figure is over five percent above the final May 2006 level of $1.45 billion and almost 33 percent above the June 2005 billings level of $1.15 billion.

"Total bookings for North American equipment manufacturers posted significant gains in the second quarter compared to the previous quarter," said Stanley T. Myers, president and CEO of SEMI. "It has been encouraging to see this sustained level of growth over the past seven months, and we are confident that 2006 will mark the second biggest growth year for our 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.
