Abstract
Overview
The SEMI® Historical Book-to-Bill Data provides global bookings and billings by months for North American-based semiconductor equipment manufacturers for the period from 1991 to 2007. 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.
Methodology
SEMI uses a third-party accounting firm to manage their market statistics data collection program. Bookings and billings figures are sent directly to the firm, from participating member companies. Individual company data is not available to any agency or company, including SEMI. Confidentiality is guaranteed, and market share information for the program participants is never published.
