SEMI posts book-to-bill ratio of 0.94 in June

KUALA LUMPUR: North America-based manufacturers of semiconductor equipment posted US$1.55 billion in orders in June 2011 and a book-to-bill ratio of 0.94, according the US-based Semiconductor Equipment Manufacturers Industry association (SEMI).

The three-month average of worldwide bookings in June 2011 fell 4.4% month-on-month to US$1.55 billion from US$1.62 billion in May, and was down 10.3% from the $1.73 billion in orders posted in June.

SEMI is the global industry association serving the manufacturing supply chains for the microelectronic, display and photovoltaic industries.

A book-to-bill of 0.94 means that US$94 worth of orders were received for every US$100 of product billed for the month.

In a statement on its website on July 19, SEMI said the three-month average of worldwide billings in June was US$1.65 billion, down 1.1% from US$1.67 billion in May, but 12.5% higher year-on-year from US$1.47 billion in June 2010.

SEMI president and CEO Stanley T Myers said the billings were up year-over-year, adding that the three-month average billings were relatively consistent.

“We will monitor bookings strength for indications of year-end or seasonal softening, but no definitive data trend is apparent yet.”

The SEMI book-to-bill is a ratio of three-month moving averages of worldwide bookings and billings for North American-based semiconductor equipment manufacturers.
