  • Patent number: 6646476
    Abstract: A circuit is provided which is constituted by TFTs of one conductivity type, and which is capable of outputting signals of a normal amplitude. When an input clock signal CK1 becomes a high level, each of TFTs (101, 103) is turned on to settle at a low level the potential at a signal output section (Out). A pulse is then input to a signal input section (In) and becomes high level. The gate potential of TFT (102) is increased to (VDD−V thN) and the gate is floated. TFT (102) is thus turned on. Then CK1 becomes low level and each of TFTs (101, 103) is turned off. Simultaneously, CK3 becomes high level and the potential at the signal output section is increased. Simultaneously, the potential at the gate of TFT (102) is increased to a level equal to or higher than (VDD+V thN) by the function of capacitor (104), so that the high level appearing at the signal output section (Out) becomes equal to VDD.

  • Patent number: 6642543
    Abstract: A functional block for a CMOS circuit within the core of an integrated circuit chip and a method of making the same is disclosed. The functional block uses both thick and thin gate oxide transistors which reduces the leakage current and increases the voltage swing while permitting the device scaling in circuits made in CMOS technology. Within the functional block, the distance between a thick oxide transistor and a thin oxide transistor is chosen based on a transistor stability criterion. The thick and thin oxide transistors can be connected to identical or different voltage sources. Further, a transistor within a functional block can be chosen to be thick or thin oxide transistor based on a leakage current threshold or a voltage swing threshold.

  • Patent number: 6639259
    Abstract: The invention relates to a CCD of the buried-channel type comprising a charge-transport channel in the form of a zone (12) of the first conductivity type, for example the n-type, in a well (13) of the opposite conductivity type, in the example the p-type. In order to obtain a drift field in the channel below one or more gates (9, 10a) to improve the charge transfer, the well is provided with a doping profile, so that the average concentration decreases in the direction of charge transport. Such a profile can be formed by covering the area of the well during the well implantation with a mask, thereby causing fewer ions to be implanted below the gates (9, 10a) than below other parts of the channel. By virtue of the invention, it is possible to produce a gate (10a) combining a comparatively large length, for example in the output stage in front of the output gate (9) to obtain sufficient storage capacity, with a high transport rate.

  • Patent number: 6635913
    Abstract: The upper electrode of a capacitor is constituted of laminated films which act to prevent hydrogen atoms from reaching the capacitor electrodes and degrading performance. In one example, a four layer upper electrode respectively act as a Schottky barrier layer, a hydrogen diffusion preventing layer, a reaction preventing layer, and an adsorption inhibiting layer. Therefore, the occurrence of a capacitance drop, imperfect insulation, and electrode peeling in the semiconductor device due to a reducing atmosphere can be prevented. In addition, the long-term reliability of the device can be improved.
