The executive vice president of market research firm, John Barber said original forecast for 2013 global semiconductor revenue is up to about $ 346 billion, harvest is up to 8.6%, but Now it seems that in 2013 PC and DRAM have opportunities to recover over 2012, but the overall economic and political changes are still uncertain in the future,so they estimate in 2013 semiconductor revenue will be $ 330 billion, an annual growth rate is also revised down to 6.9% level. As for the performance of the semiconductor market this year, John Barber said Gartner originally forecasted global semiconductor revenue in 2012 was up to about $ 319 billion, harvest was up to 4%, but since PC is not as good as expected to impact DRAM demand, so they revise down in 2012 semiconductor revenue is 309 billion U.S. dollars, an annual growth rate is revised down to 0.6% level. As to the revised global semiconductor output, John Barber said that the main reason of output decline is the PC market, because of weak PC demand in emerging markets as well as the impact of the Tablet PC, a large decrease in the PC market growth rate; Gartner also revised down the shipments of phone this year, because the demand for low-end phones is light; DRAM in the third quarter is still oversupply; NandFLASH industries are relatively more healthy. Looking ahead to 2013, John Barber assumes that the U.S. will not increase taxes, and Europe will not have double-dip recession ,next year the global output growth rate of semiconductor is 6.9%, the DRAM industry will be slightly back to health status , automotive sector is almost linked with global GDP index; NANDFLASH stabilize while the related manufacturers such as Toshiba cuts ,2013 revenue will have strong growth.
