SAN JOSE, Calif. — May 24, 2016 — North America-based manufacturers of semiconductor equipment posted $1.59 billion in orders worldwide in April 2016 (three-month average basis) and a book-to-bill ratio of 1.10, according to the April  Equipment Market Data Subscription (EMDS) Book-to-Bill Report published today by SEMI.  A book-to-bill of 1.10 means that $110 worth of orders were received for every $100 of product billed for the month.

SEMI reports that the three-month average of worldwide bookings in April 2016 was $1.59 billion. The bookings figure is 15.6 percent higher than the final March 2016 level of $1.38 billion, and is 1.3 percent higher than the April 2015 order level of $1.57 billion.

The three-month average of worldwide billings in April 2016 was $1.46 billion. The billings figure is 21.5 percent higher than the final March 2016 level of $1.20 billion, and is 4.0 percent lower than the April 2015 billings level of $1.52 billion.

"Bookings reached their highest levels in eight months and billings levels also significantly improved in April,” said Denny McGuirk, president and CEO of SEMI. "The data reflect strong investments in 3D NAND and in China."

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.
