Abstract
MEMS devices (such as interferometric modulators) may be fabricated using thin film transistor (TFT) manufacturing techniques. In an embodiment, a MEMS manufacturing process includes identifying a TFT production line and arranging for the manufacture of MEMS devices on the TFT production line. In another embodiment, an interferometric modulator is at least partially fabricated on a production line previously configured for TFT production.
