SEMI reports that the three-month average of worldwide bookings in November 2015 was $1.24 billion. The bookings figure is 6.7 percent lower than the final October 2015 level of $1.33 billion, and is 1.7 percent higher than the November 2014 order level of $1.22 billion.

The three-month average of worldwide billings in November 2015 was $1.29 billion. The billings figure is 5.2 percent lower than the final October 2015 level of $1.36 billion, and is 8.3 percent higher than the November 2014 billings level of $1.19 billion.

"The semiconductor equipment book-to-bill ratio continued to decelerate in the fourth quarter," said Terry Tsao, president of SEMI Taiwan. “In light of this recent softening and with the currently strong U.S. dollar, SEMI anticipates that the total equipment market (billings) will be flat to slightly down this year vs. last year as reported in U.S. dollars."
