Title: Semiconductor device
Inventor: NAKABAYASHI MASAKAZU
IPC: H01L29/866
Filed: 1988-12-05
Abstract: PURPOSE:To prevent hot carriers from jumping into an oxide film by a method wherein an n<->-type region whose concentration is slightly higher than that of a p-type layer is provided around an n<+>-type emitter layer. CONSTITUTION:A semiconductor device of this design is different from a conventional one in such a point that an n<->-type emitter layer 7 is diffused around an n<+>-type emitter layer 3. Here, when a reverse vias is applied, as the concentration of the n<->-type emitter layer 7 is slightly higher than that of a p-type layer 2, a depletion layer 8 does not much spread in the p-type layer 2. Thereby, the depletion layer 8 spreads through the n<+>-type emitter layer 3 as the n<->-type emitter layer 7 approaches in a bulk direction, so that a breakdown region 9 is made separate from the surface. By this setup, hot carriers occurred here hardly jump into an oxide film 6 and are not trapped in the oxide film 6, so that a semiconductor device of this design can be stable in reliability.

Title: Digital/analog conversion circuit
Inventor: SHOMURA ATARU
IPC: H03M1/66
Filed: 1986-12-29
Abstract: PURPOSE:To attain low noise by providing plural D/A conversion circuits converting a digital signal into a PAM signal and giving an output while eliminating the harmonic component and an adder circuit adding the outputs. CONSTITUTION:D/A converters 11a, 12a in 1st and 2nd D/A converter circuits 11, 12 generate respectively a PAM signal from a digital signal supplied to each input terminal IN and supply the PAM signal to low-pass filters 11b, 12b. The filters 11b, 12b eliminate the harmonics included in the PAM signal respectively and pass selectively only a low frequency signal component and give the result to input terminals 13a, 13b of the adder 13. The amplitude of the signal component included in the output of the adder 13 is twice the amplitude of each. Since the noise component included in each of the outputs of the D/A converter circuits 11, 12 is in the random phase relation, the amplitude after the addition is 2<1/2> times of each amplitude. Thus, the S/N is improved by a multiple of 2<1/2>.
