  • Patent number: 6262461
    Abstract: A method of fabricating a field effect transistor including doping a continuous blanket layer in a semiconductor substrate structure adjacent the surface to include a source area and a drain area spaced from the source area. A high dielectric constant insulator layer is positioned on the surface of the semiconductor substrate structure overlying the continuous blanket layer to define a gate area between the source and drain areas. A gate contact on the insulator layer is selected to provide a work function difference that depletes the doped layer beneath the insulator layer. Further, the doped layer depth and dosage are designed such that the doped layer is depleted beneath the insulator layer by the selected work function difference of the gate contact and the semiconductor substrate.

  • Patent number: 6166766
    Abstract: A sensing circuit (202) uses correlated double sampling to sample a first pixel signal of a pixel stream (V.sub.PIXEL) at two different times to produce a dark signal and a light signal on two capacitors (310, 314). The dark and light signals are amplified in an amplifier (302) to produce a differential output signal (V.sub.PP -V.sub.PN) proportional to their difference. While the samples of the first pixel signal are being amplified, a second pixel signal is double-sampled to produce dark and light signals on two other capacitors (312, 316) for amplifying in the same amplifier. The period of the pixel signal is divided into time slots (T.sub.1 -T.sub.16) by a clocked oscillator (52). Programming signals (PROG1, PROG2) control the time slots in which sampling control pulses (V.sub.S1, V.sub.S2) are generated.
