Abstract: PROBLEM TO BE SOLVED: To correct the difference in threshold voltage using a method other than a channel dope method, by utilizing a short channel effect and a narrow channel effect which are generated along with fine processing of a device element. SOLUTION: A CMOS structure which has a complementary combination of an N-channel semiconductor device and a P-channel semiconductor device formed on a substrate 607 having an insulating surface is provided. In such a semiconductor device, the absolute values of threshold voltages of the N- channel semiconductor device and the P-channel semiconductor device are made substantially the same. Therefore, means for reinforcing a narrow channel effect is provided in the N-channel semiconductor device, and means for reinforcing a short channel effect is provided in the P-channel semiconductor device.  For example, the layout interval between impurity regions 605, 606 which are locally laid out substantially in parallel to a channel direction in a channel forming region is intentionally narrowed in the N-channel semiconductor device, and is relatively broadened in the P-channel semiconductor device.

Abstract: PURPOSE:To facilitate process reduction for levelling and avoid mingling of impurity by a method wherein the surface of a device is quickly covered with aluminum with which contact holes are levelled and selective growth is switched to total growth in a short time in the same chamber. CONSTITUTION:On a silicon substrate 4, source and drain regions 3 are formed by implantation of ions of impurity having a conductivity type opposite to that of the substrate 4 and a gate electrode 2 is formed with agate oxide film between. After a silicon oxide film 1 is formed over the whole surface, contact wholes 5 are formed. Then the contact holes 5 are filled with aluminum 6 by selective growth using chemical vapor deposition. Then an ultraviolet radiation of a deuterium lamp is applied over the whole surface including the silicon oxide film 1 to deposit a very thin layer of aluminum 7. If the total growth of aluminum 7 is once started by the sufficiently short time light application, the total growth can be continued under selective growth conditions even if the light application is discontinued. With this constitution, the deterioration of electrical characteristics between the films formed by different processes can be avoided and excellent quality aluminum can be deposited.

Filed: 1993-11-16
Abstract: PURPOSE:To prevent a discontinuous point from being reproduced as a noise when the discontinuous point of a DC voltage level occurs at the point of time of releasing last value hold in a digital audio signal process. CONSTITUTION:An audio data correction circuit 40 is used for a reproducing device. In the reproducing device, an error correction circuit 3 corrects an error by using an error correction code added to the recording data on a recording medium 2, and when the correction remainder exists, the circuit 3 outputs an error flag 13 at every sample together with the regenerative signal 12 of the recording data. In the audio data correction circuit 40, a control circuit 5 receives the error flag 13, and a correction process circuit 4 holds the data before the flag is outputted while outputting the flag. Further, a memory 8 delays the regenerative signal 12 by the prescribed number of samples. Thereafter, a comparator 7 calculates a difference amount between the hold data at the point of time when the error flag 13 is released and the regenerative signal. By using the difference amount, an ALU 6 changes the hold data gradually in the prescribed number of samples, and connects the hold data with the data at the point of time of releasing the hold continuously.
