Yole Développement’s figures only count the MEMS manufacturing value, not the value of the ASIC, even if bonded to the MEMS device.

 

Thanks to its contract production for Hewlett Packard, STMicroelectronics continues to dominate the MEMS foundry business. Though ST’s foundry income declined about 20% last year when demand for HP’s inkjet heads dropped off, its $200M in revenue still accounted for almost one-third of the ~$600M MEMS foundry business.

 

Meanwhile, Sony’s foundry revenues benefited from strong MEMS microphone demand for mobile phones and tablets. Thanks to this, along with Sony’s contract production for Knowles Electronics, the company achieved ~30% growth.

 

Beneath these two large-contract/single-customer producers exists a tight cluster of leading open foundries with sales between $30M – $40M, including TSMC, Teledyne DALSA, Silex Microsystems, and the combined sales of Asia Pacific Microsystems and its parent, UMC.
