MEMS foundries shared unequally in the MEMS market's robust 25% growth in 2010, according to rankings by Yole Developpement. Total combined revenues by the Top 20 MEMS foundries— which account for the vast majority of world's total MEMS foundry capacity— climbed about 10% last year, as companies doing internal production grabbed most of the big growth in key markets. STMicro captured nearly a third of the total, but there was plenty of reshuffling elsewhere: Silex is now the largest pure-play independent thanks to its via-first highly doped silicon TSV technology, Sensonor vaulted onto the list as a TPMS foundry spinofF, and TI slipped as user demand shifts to permanent inkjet printer heads.
