SAN FRANCISCO—The ratio of bookings to billings for North America-based semiconductor equipment manufacturers declined for the fifth straight month in August, according to the fab tool vendor trade group SEMI.
North American fab tool manufacturers posted a book-to-bill ratio of 0.84 on a three-month average basis in August, down from 0.86 the month before, SEMI said.
The three-month average of worldwide books for North American tool vendors was $1.12 billion in August, down 9 percent from July and down 4 percent from August 2011, according to SEMI (San Jose, Calif.) The group posted billings of $1.34 billion on a three-month average basis in August, down 7 percent from July and down 8 percent from August 2011, SEMI said.
A book-to-bill of 0.84 means that $84 worth of orders was received for every $100 of product billed for the month.
"The second half of the year continues to show reduced order and billing levels for the 2012 spending cycle," said Dan Tracy, senior director of SEMI industry research and statistics, in a statement. "We expect 2012 equipment revenues to decline slightly with total spending for front-end and back-end semiconductor equipment globally remaining at the $40 billion or greater level for the third consecutive year."
