Semiconductor Equipment and Materials International (SEMI) association yesterday (21) announced in July North American semiconductor equipment orders shipments ratio (Book-to-BillRatio, B / B value) of 1.00, although more than seven consecutive months of expansion on behalf of the semiconductor market boom 1, but the amount of orders growth momentum has slowed. SEMI pointed out, the economy seems to have reached a turning point in this wave cycle, market trends in the coming months may appear reversed changes.SEMI announced in July 2013 the North American semiconductor equipment B / B value of 1.00, the seventh consecutive month of expansion in the economy on behalf of more than one. Among them, the July 3 months average order amount of $ 1,273,100,000, compared with June a revised $ 1,334,200,000, decline 4.6% in the same period in 2012, $ 1,234,600,000 will grow 3.1%, the annual rate of change after 15 months for the first time from negative to positive.Performance in the semiconductor equipment shipments, in July of three average monthly shipments amounted to $ 1.269 billion, compared with June a revised $ 1.214 billion grew 4.6% in 2012 compared to $ 1.443 billion over the same period, a 12% decline still However, the rate of decline has been significantly reduced.Overall, the approximate amount of orders declined in July, but the amount shipped a record 11 months since a new high, book to bill ratio remained at a more than in June but fell 1.1 represents the semiconductor market is still in the expansion phase, but the expansion rate has been slowed.SEMI president and CEO DennyMcGuirk said that although the amount for the semiconductor device shipments continued to rise, the book to bill ratio is continuously maintained at 7 months or more, but the amount of information on orders weakened slightly overall, although whether changes in the economy still depends on changes in the coming months to determine the data, but the market has been the trend in the coming months are likely to shift.Due to the global semiconductor factory is still pursuing process scaling and invest and build factories in industry, only TSMC, Samsung, Intel and other three manufacturers, and including TSMC, including, most equipment purchase orders have been issued in the first half, the second half of the new equipment procurement action turned cautious, if the amount of decline in orders, shipments upward trend in the amount of established orders shipped more than likely in the next 1 to 2 months below 1.Equipment industry, said the world's major semiconductor plant in the third quarter revenue forecast to grow although compared with the second quarter, but the growth rate slowed down, on behalf of the market has reached a high point of the business cycle signs, although demand is still mobile devices good, but PC / NB and consumer electronics demand is lower than expected, with memory prices fell rapidly from high point, semiconductor plant in the second half of the investment action may indeed slow down.
