North American Semiconductor Equipment Industry Posts May 2013 Book-to-Bill Ratio of 1.08

SAN JOSE, Calif. — June 20, 2013 — North America-based manufacturers of semiconductor equipment posted $1.32 billion in orders worldwide in May 2013 (three-month average basis) and a book-to-bill ratio of 1.08, according to the May EMDS Book-to-Bill Report published today by SEMI. A book-to-bill of 1.08 means that $108 worth of orders were received for every $100 of product billed for the month.

The SEMI Book-to-Bill Report provides a first look at the book-to-bill ratio for North American Headquartered Semiconductor Equipment Manufacturers. The three-month average global bookings and billings are a strong indicator for trends in the worldwide semiconductor industry. SEMI follows the protocol established by the U.S. Department of Commerce in publishing our figures only on a three-month average basis. We do this in order to smooth out the natural volatility in bookings. This report is distributed monthly approximately three weeks after the close of each month. Categories covered include front-end (wafer processing/mask/reticle/wafer manufacturing/fab facilities) equipment and final manufacturing (assembly/packaging/test) equipment.

Other notes

In addition to the SEMI Book-to-Bill report, two other organizations offer data on book-to-bill trends. The following description explains the coverage of those two reports:

The Semiconductor Equipment Association of Japan (SEAJ) is a Japanese organization of semiconductor, liquid crystal display (LCD), and related manufacturing equipment manufacturers. The SEAJ issues a monthly book-to-bill report based on three-month average global bookings and billings of Japanese headquartered equipment manufacturers. The SEAJ Book-to-Bill Report is issued on or shortly after the SEMI book-to-bill report release date. Visit for additional info about this organization.

VLSI Research issues a worldwide book-to-bill ratio each month based on a combination of original equipment manufacturer (OEM) surveys and models. The VLSI Research book-to-bill reports actual bookings and billings each month, not three-month averages. VLSI’s data include systems to manufacture integrated circuits, thin film heads, liquid crystal displays and MEMS, as well as spares and services.
