摘要： In the fabrication of a CMOS-TFT, non-selectively doping (for both of p- and n-type TFTS) and selectively doping (only for the n-type TFT) with p-type impurities (B: boron) are successively performed at very low concentrations to control the threshold voltages (Vthp and Vthn). More specifically, the Id-Vg characteristics of the p- and n-type TFTs are initially negatively shifted. In this state, non-selectively doping is performed positively to shift the p- and n-type TFTs first to adjust the Vthp to a specified value. Selectively doping is then performed positively to shift only the n-type TFT to adjust the Vthn to a specified value. The threshold voltages of the p- and n-type TFTs constructing the CMOS-TFT can be independently and efficiently (with minimum photolithography) controlled with high accuracy.

摘要： A liquid crystal device comprising, at least, a liquid crystal element comprising at least a pair of substrates and a liquid crystal material disposed between the pair of electrodes, and electric field-applying means for applying an electric field to the liquid crystal element. The electric field-applying means applies a reverse electric field (−TINT) so as to cancel an orientation energy difference (TINT) depending upon relative directions between the applied electric field and aligned liquid crystal molecular axis in the liquid crystal element. There is provided a liquid crystal device capable of effectively suppressing the reduction in contrast, even when the optical response speed is increased.
