Reclamation of GaAs Wafers by Chemical Stripping & Polishing Harvey Kitzmiller, Process Engineer & Sean Quinn, CEO Wafer World, Inc., West Palm Beach, Florida, USA Abstract Gallium Arsenide (GaAs) is one of the most important compound semiconductor materials in the world, and it has wide applications in wireless, opto-electronics, and Solar Cells. As a cost-savings measure, companies are forced to re-use substrates when feasible. Most of the major GaAs companies in the Unites States have reclaimed 4” and 6” GaAs wafers for many years. Diameters of 2”, 3”, 4”, 5”and 6” wafers can be processed and re-polished. Process Monitor wafers or Production-Rejects can be reclaimed 2-3 times and used as Test Grade material. Wafers with layers consisting of epitaxy, photo-resist, metal coating, dielectrics, etc. can be reclaimed 2-3 times as well! The process flow chart for reclaim wafers at Wafer World, Inc. is presented. The economical benefits for reclamation of GaAs wafers are discussed in this paper as well.

GaAs device demand will continue to see growth through 2014 Compound Semiconductor October 2010, vol. 16, number 7, pg 8 The GaAs market staged a strong recovery toward the end of a tumultuous 2009 as a result of positive trends in wireless markets. The Strategy Analytics GaAs and Semiconductor Technologies (GaAs) service report, “GaAs Industry Forecast ,” calculates that despite a recession, GaAs industry revenues managed to escape a drop in 2009, with a strong performance in the second half of the year translating to year-on-year revenues remaining flat at $3.7 billion. GaAs technology will maintain its position as the enabling technology for next generation cellular handsets. The smartphone category of the handset market, in particular, provided a vital lifeline in 2009, boasting stronger than average annual growth in terminal volumes. With an increasing average number of GaAs power amplifiers per terminal as well as increasing switch complexity in this sector, GaAs device demand from next generation handsets will grow faster than overall industry revenue growth. “Our analysis incorporates individual wireless, consumer, infrastructure and defense market forecasts- taking into account technology trends,” noted Asif Anwar at Strategy Analytics. “There is no question that the improving capabilities of silicon and silicon germanium technologies, as well as emerging technologies such as gallium nitride, will provide increasing competition for GaAs technologies.” “Despite this competition, GaAs device demand will continue to see continued growth through The market will grow at a compound annual growth rate of 5% to be worth over $4.7 billion,” concluded Anwar. Reclaiming GaAs Wafers As GaAs wafer usage continues to rise, GaAs reclaim becomes an even more important cost savings tool – allowing your company to decrease prime wafer purchases.
