Semiconductor tool orders slide below billion-dollar mark in September

October 21, 2011 — Awaiting "stability in the overall economic outlook," semiconductor device makers spent 40.4% less with North America-based manufacturers of semiconductor fab equipment year-over-year in September 2011. The September book-to-bill ratio published by SEMI fell to 0.75.

Worldwide bookings in September 2011 totaled $984.8 million, a 15.3% drop month-to-month, tipping below the billion mark. Year-over-year, bookings fell 40.4% ($1.65 billion in September 2010).

Worldwide billings from North American semiconductor fab tool makers in September 2011 was $1.31 billion, 9.8% less than August and 18.4% below September 2010 billings.

Bookings nearly reached the level last seen in late 2009, noted Stanley T. Myers, president and CEO of SEMI. Myers says that device makers "are investing in advanced technology," but are waiting out macro-economic uncertainties before making broader investments.

The data are contained in a monthly Book-to-Bill Report published by SEMI. The report tracks billings and bookings worldwide of North American-headquartered manufacturers of equipment used to manufacture semiconductor devices, not billings and bookings of the chips themselves. The Book-to-Bill report is one of three reports included with the Equipment Market Data Subscription (EMDS).
