Title: Manufacture of semiconductor device
Inventor: KURIYAMA TOSHIHIRO
IPC: H01L21/265
Filed: 1985-09-11
Abstract: PURPOSE:To obtain an LDD structure by oxidizing process, which is a stable and highly controllable method, with low cost and high quality by introducing boron and an N-type impurity under a gate electrode of an N-type channel MIS.FET. CONSTITUTION:Phosphorus and boron are implanted into a surface of a P-type silicon substrate 1 and a gate oxide film 2 and a phosphorus-doped polycrystalline silicon gate electrode 3 are formed by annealing and heat treatment is carried out. At that time, boron in the silicon substrate surface is absorbed by an oxide film 5a and, on the contrary, phosphorus is excluded and phosphorus concentration becomes relatively high near the silicon surface and a low concentration N-type impurity layer is formed. Edges of the polycrystalline silicon gate electrode 3 retreat by oxidization and boron in the silicon substrate is successively absorbed out and, along with the progress of oxidization of the sides of the polycrystalline silicon gate electrode 3, the low concentration N-type impurity layer is formed self-aligningly. Then, by implantation of arsenic, a high concentration N-type impurity layer can be formed at the position apart from the effective polycrystalline silicon gate electrode 3 by the thickness of an oxide film 5b on the side wall so that an LDD structure can be obtained.

Title: Gamma correcting device for video camera
Inventor: KITAMURA YOSHINORI
IPC: H04N5/202
Filed: 1984-09-25
Abstract: PURPOSE:To prevent the deterioration in an SN ratio and to reduce the power consumption by overlapping a DC signal in accordance with gains of an AGC circuit after the signal from an image pickup element is AGC-amplified and removing said DC signal from the signal obtained by gamma-correcting the over-lapped signal. CONSTITUTION:After the output signal of an image pickup element 1 is ampli fied by a pre-amplifier 2 and gain control circuit 6 to the signal of a certain amplitude value, the color of said signal is separated by a color separator circuit 3. After the output signal of the color separator circuit 3 is overlapped with a DC signal 10' generated by a corrected signal generator 10 in accordance with gains of the gain control circuit 6, a gamma-correction 4 is executed. Then the DC signal 10' overlapped by a clamp circuit 9 is removed. As a result, since the reference point of a gamma-correction (d) is moved from P to Q when a subject is dark and an SN ratio is poor, the correction quantity is reduced, thereby preventing the deterioration of the SN ratio. Moreover, since prior to the signal processing the gain control is carried out, afterward the power source voltage of the circuit can be set low, and the power consumption can be reduced accordingly.
