Below is Semi’s March 2007 Book-to-Bill Report. The monthly Book-to-Bill 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. The 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.
