SAN JOSE – North American-based manufacturers of semiconductor equipment posted $1.65 billion in orders in May on a three-month average basis and a book-to-bill ratio of 1.12 according to the latest data from SEMI.

A book-to-bill of 1.12 means that $112 worth of orders were received for every $100 of product billed for the month.
The three-month average of worldwide bookings in May was $1.65 billion, or 3% higher than the revised April level of $1.6 billion and over 62% higher than May 2005.

The three-month average of worldwide billings in May was $1.48 billion, also 3% above the final April level of $1.44 billion and 22% above the May 2005 billings.

"Semiconductor fabrication facilities worldwide are utilizing high levels of available manufacturing capacity and equipment bookings have been steadily increasing,” said Dan P. Tracy, Ph.D., senior director of Industry Research and Statistics at SEMI. "Total bookings for North American-based equipment makers remained strong into the second quarter and are well above the same period last year.”

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.
