North American chip fab tool book-to-bill up in November

December 16, 2011 — North America-based manufacturers of semiconductor equipment posted $973.3 million in orders in November 2011, $1.17 billion in billings, and a book-to-bill ratio of 0.83, according to the November Book-to-Bill Report from SEMI.

The three-month average of worldwide bookings in November 2011 was $973.3 million. The bookings figure is 5.0% above October’s level, though 35.7% below November 2010.

The three-month average of worldwide billings in November 2011 was $1.17 billion. The billings figure is 6.7% below October 2011, and 25.1% less than November 2010 billings.

"We see improvement in the book-to-bill ratio due to a slight increase in bookings as we approach the end of 2011," said Denny McGuirk, president and CEO of SEMI. "The industry waits for definitive signs of stability in the worldwide economy, which will improve end market demand and help solidify investment plans for 2012."

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. 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 data contained in this release were 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. The Book-to-Bill report is one of three reports included with the Equipment Market Data Subscription (EMDS).

SEMI is a global industry association serving the nano- and micro-electronic manufacturing supply chains. For more information, visit
