Filed: 1981-10-14
Abstract: PURPOSE:To improve the moisture resistance of a semiconductor device by containing a substance having corrosion rate larger than a substance forming electrodes in resin, thereby increasing the insolubility of the electrodes. CONSTITUTION:Other substance 11 is contained in resin 1. This substance 11 has high corrosion degree for water, exhibiting a linear line of more soluble (b) then (a), showing the corrosion of electrode metal 31. In this graph, abscissa axis represents time (t), ordinate axis represents remaining corrosion amount W. When the periphery is covered with resin like a semiconductor container and immersed moisture is limited to small amount, the substance 11 is dissolved. Accordingly, ions which contribute to the corrosion are neutralized, with the result that the corrosion velocity of the metal 31 is decelerated from (a) to (a'). From this principle, the water repellency of the electrode 31 is improved. The material 11 employs an insulator.
