Title: Silicon carbide semiconductor device and its manufacturing method
Inventor: OKUNO HIDEKAZU
IPC: H01L21/336
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a recrystallization and activation heat treatment technique which changes an ion implanted region into a single crystal type and to enhance the breakdown strength of a silicon carbide semiconductor device. SOLUTION: P-type impurities are implanted at an acceleration energy of 1 MeV or higher. After that, a heat treatment is executed by a laser. Thereby, the implanted impurities are activated, and p- type base regions 3a, 3b are recrystallized. For example, by an excimer laser, the laser is irradiated sequentially toward upper-side ends from lower-side ends of the p- type base regions 3a, 3b. Thereby, the crystal type of an n+ type epitaxial layer 2 which is situated under the p- type base regions 3a, 3b is made to succeed, and the p- type base regions 3a, 3b are formed to be of the same crystal type. Consequently, the breakdown strength of the silicon carbide semiconductor device is enhanced more than in a case in which the central part of the p- type base regions 3a, 3b is formed of 3C-SiC.

Filed: 1986-11-04
Abstract: PURPOSE:To obtain a binary signal reflecting the fine features of an input multivalue signal without measuring distribution or the like by outputting a value '0' or '1' different from the values of its adjacent sections as a binary signal for every signal value section obtained by dividing a signal value into plural sections. CONSTITUTION:Thresholds T1-T5 indicating the borders of sections are supplied to threshold input terminals 3A-3E. The value of the thresholds are compared with that of image signal values obtained from a signal line 2 by comparators 5A-5E, and when the image signal value is smaller than the threshold value, a value '1' is outputted to signal lines 6A-6E. In the other case, a value '0' is outputted to the 6A-6E. The output values are sent to AND circuits 7A, 7B and an inverter 8 and logically operated results are outputted to signal lines 9A, 9B, 10. In this case, the output value is '1' on the line 9A when an input multivalue signal value L is T1<L<=T2, '1' on the line 9B at the time of T3<L<=T4, '1' on the line 10 at the time of T5<L, and '0' in other cases. The OR operation of these output values is executed by an OR circuit 11 and the obtained OR is outputted to an output terminal 13 as it is. The output is '1' in either case of T1<L<=T2, T3<L<=T4 and T5<L, and '0' in other cases.

Abstract: PURPOSE:To prevent the interference of dots by selecting an output from a horizontal filter or a vertical filter for pictures with especially strong correlation according to results that correlation energies in vertical and horizontal directions are detected and outputting chrominance signal. CONSTITUTION:Outputs 112 and 113 from a vertical correlation detection circuit 7a and a horizontal correlation detection circuit 7b are given to a decision circuit 8, while its output 114 is given to a switch circuit 9. Its output 115 is outputted as chrominance signal from an output terminal 2. With the outputs 112 and 113 from the vertical and horizontal correlation detection circuits 7a and 7b as inputs, the decision circuit 8 outputs a selection signal 114 and controls the output from the switch circuit 9. The chrominance signal outputted from the switch circuit 9 is subtracted from the composite signal of a compensation delay circuit 5h, thereby obtaining a luminance signal 117. Thus the leakage of the luminance signal and the chrominance signal in an area that suddenly changes to mutual channels can be minimized, and the dot interference can be reduced.
