Sales of semiconductor equipment in North America continue to demonstrate strong growth North America-based manufacturers of semiconductor equipment posted $1.44 billion in orders worldwide in April 2014 (three-month average basis) and a book-to-bill ratio of 1.03, according to the April EMDS Book-to-Bill Report published today by SEMI. A book-to-bill of 1.03 means that $103 worth of orders were received for every $100 of product billed for the month. The three-month average of worldwide bookings in April 2014 was $1.44 billion. The bookings figure is 10.8 percent higher than the final March 2014 level of $1.30 billion, and is 22.5 percent higher than the April 2013 order level of $1.17 billion. The three-month average of worldwide billings in April 2014 was $1.40 billion. The billings figure is 14.1 percent higher than the final March 2014 level of $1.23 billion, and is 28.7 percent higher than the April 2013 billings level of $1.09 billion. “Sales of semiconductor manufacturing equipment from North American producers continue to demonstrate strong sequential and year-over-year growth,” said Denny McGuirk, president and CEO of SEMI. “The data through the first quarter reflects momentum in memory, foundry, and back-end spending.” 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.
