The SEMI Book-to-Bill annual subscription provides global bookings and billings by month for North American-based semiconductor equipment manufacturers. The data includes front-end (Wafer Processing, mask/Reticle, Wafer Mfg., Fab Facilities) and final manufacturing (Test, Assembly & Packaging). The Book-to-Bill report is calculated by taking a three-month moving average of North American headquartered equipment manufacturers bookings divided by a three-month average of billings for the same period of time. North American equipment suppliers represent approximately 50 percent of the worldwide equipment market. A Book-to-bill ratio above one represents an expanding market while a book-to-bill ratio below one represents a contracting market.
