Association of Semiconductor Equipment and Materials International (SEMI) announced in November 2013 the North American semiconductor equipment manufacturers to-bill ratio (Book-to-Billratio) preliminary estimates of 1.11, 1.05 higher than in October, the third consecutive rise in two months and greater than 1. 1.11 shipped $ 100 per month means that products can receive $ 111 worth of new orders.SEMI This Preliminary data show that in November the North American semiconductor equipment manufacturers worldwide orders received three-month moving average amount of preliminary estimates of $ 1.24 billion, compared with $ 1.12 billion in October increased by 10.1%, and compared to the same period in 2012 $ 718.6 million surged 72.3%.November semiconductor equipment manufacturer in North America three-month moving average of the amount initially estimated shipments of $ 1.11 billion, compared with $ 1.07 billion in October rose 4.0%, and $ 910.1 million in 2012 compared to the same period increased by 22.4%.SEMI president and chief executive officer DennyMcGuirk said Yang equipment orders continued to display orders but also a lot of activity at the end of a strong year ago, this point of view, 2014 should be able to rebound in equipment spending.
