Title: Manufacture of surface acoustic wave element
Inventor: NISHIHARA TOKIHIRO
IPC: H01L21/3065
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To suppress after corrosion and to suppress holing of a substrate under an electrode by using an etching gas, consisting of a mixed gas of Cl2 and He and etching under a gas pressure within a specific range. SOLUTION: In dry etching of an Al alloy, Cl2 gas is used for etching rate increase of the Al alloy, and a reducing gas is added to this in order to eliminate natural oxidized film. Also, a gas including an additive halogen to the Cl2 gas becomes a component for sidewall protection film and prevents side etching. When an Al electrode includes a metal whose vapor pressure of a halide is low, however, a residual dross is generated or etching does not proceed. So, the etching gas of a mixed gas of Cl2 and He is used, and etching is performed under a gas pressure of 0.1 to 3 Pa. Under this pressure, it is possible to suppress scatter of He, to take a large average free process and to obtain stable plasma discharge, and selectivity of an electrode and resist is improved.

Abstract: PURPOSE:To obtain a highly reliable integrated circuit, to which a stable Zener voltage can be applied, by providing a P-N junction, which is utilized as the Zener diode, in the inside of a semiconductor substrate, and eliminating the effect of the surface to the Zener voltage. CONSTITUTION:In a P type silicon substrate 1, an N<+> embedded layer 11 is formed at the same time with the formation of a collector embedded layer in a transistor element part. An N type epitaxial layer 2 is formed. An isolating regions 3 and a P type region 12 reaching the embedded layer 11 are formed. A (P) region 13 is diffused simultaneously with the formation of the base region in the transistor element part. An N<+> region 14 is diffused simultaneously with the formation of the emitter region. A voltage is applied between an anode electrode 5 and a cathode electrode 6, which are contacted with the (P) region 12 and the surface of the N<+> region 14. The Zener voltage at the junction between the (P) region 12 and the N<+> layer 11 is lower than the breakdown voltage between the (P) regions 12 and 13 and the (N) layer 2. Therefore the function of the Zener diode is obtained. Since the junction is arranged in the inside, the effect of the surface is not received, and the Zener voltage is not fluctuated.

Filed: 1986-03-31
Abstract: PURPOSE:To switch a circuit without a code error and to prevent malfunction even if the bit of a data signal to be transmitted seldom changes by permitting an additional bit string group to include the bit of the preset phase. CONSTITUTION:When a current circuit SYS-1 is switched to an alternative circuit SP without a code error, a comparison circuit/compares the bits of data signals S14 and S4. If they are dissident, the circuit 1 generates a replacement control signal CS22 to control a replacement circuit 24 and causes said circuit 24 to circulatingly replace the sequential order of a string made of data signals S7 one by one. Even if the bit of the data signal S0 hardly changes, bits on one line in the data signals S14 and S4 that the comparator circuit 1 bit-compares are inverted. Therefore the comparator circuit 1 can easily identity the difference between sequential number in the circulating string made of the data signals S14 and S4, and never develops malfunction.
