Installed 300mm Wafer Capacity To Significantly Rise by 2017


Integrated circuit production using 300mm wafers is forecast to steadily increase and reach 70.4% in 2017, according to a IC Insights report.

Since 2008, the majority of integrated circuit production has taken place on 300mm wafers. In terms of surface area shipped, 300mm wafers represented 56% of worldwide installed capacity in December 2012.

For the most part, 300mm fabs are, and will continue to be, limited to production of high-volume, commodity-type devices like DRAMs and flash memories, and very recently image sensors and power management devices; complex logic and microcomponent ICs with large die sizes; and products manufactured by foundries, which can fill a 300mm fab by combining wafer orders from many sources.

The list of companies with the most 300mm wafer capacity includes DRAM and flash memory suppliers like Samsung, SK Hynix, Toshiba, Micron, Elpida, and Nanya; the industry?s biggest IC manufacturer and dominant MPU supplier Intel; and two of the world?s largest pure-play foundries TSMC and GlobalFoundries. These companies offer the types of ICs that benefit most from using the largest wafer size available to best amortize the manufacturing cost per die.

When the pending acquisition of Elpida by Micron goes through, the merged company will have the industry's second-largest share of 300mm wafer fabrication capacity, trailing only fellow memory chip manufacturer Samsung.

Meanwhile, the share of the industry?s monthly wafer capacity represented by 200mm wafers is expected to drop from 32% in December 2012 to 21% in December 2017. Fabs running 200mm wafers will continue to be profitable for many more years and be used to fabricate numerous types of ICs, such as specialty memories, image sensors, display drivers, microcontrollers, analog products, and MEMS-based devices. Such devices are certainly practical in fully depreciated 200mm fabs that were formerly used in making devices now produced on 300mm wafers.

A worrisome trend from the perspective of companies that supply equipment and materials to chip makers is that as the industry moves IC fabrication onto larger wafers in bigger fabs, the group of IC manufacturers continues to shrink in number. There are about 61% fewer companies that own and operate 300mm wafer fabs than 200mm fabs. The distribution of worldwide 300mm wafer capacity among those manufacturers is very top-heavy. Essentially, there are only about 15 companies that comprise the entire future total available market (TAM) for leading-edge IC fabrication equipment and materials, according to IC Insights report. When 450mm wafer fabrication technology comes into existence, this manufacturer group is predicted to shrink even further to a maximum of just 10 companies, and a few of those are questionable. Despite growing momentum, IC Insights expects that 450mm wafer capacity will account for only one-tenth of a percent of global IC capacity in December 2017.
