IPC: H01L27/06
Filed: 1982-12-07
Abstract: PURPOSE:To improve the strength to the breakdown of an MOSIC due to static electricity or a high voltage over the rating by a method wherein the ratio of the width of a small crystal Si, rectangular to the direction of electric signal transmission, to the length along the direction of electric signal transmission of a polycrystalline Si is set less than a specific value on a mask. CONSTITUTION:While latch-up phenomenon is avoided by setting at 6 or less the ratio L/W of the length L and the width W of the polycrystalline Si 105 which connects a bonding pad 1 and a clamp protection diode 3, the breakdown of a field oxide film due to an excess input voltage is prevented. As compared with a conventional device whose ratio L/W is taken large, for example, when the ratio L/W of the polycrystalline Si is 10, a voltage of 400-500V is just applied instantaneously between an input terminal and a semiconductor substrate, and the field oxide film is easily broken down at a contact part 107 between a connection aluminum wiring 104 from the bonding pad 1 and the polycrystalline Si 105; on the other hand, under the same condition at the ratio L/W=5, the breakdown of the field oxide film does not at all appear, and the latch-up withstand strength turns to the same level as that at the ratio L/W=10.
