Abstract: PURPOSE: To provide a semiconductor integrated circuit memory device having a high reliability and free of malfunctions that might take place due to the presence of alpha particles by covering at least part of the inside wall of a package with a metallic material of high purity, or impurities not exceeding 0.001ppm.  
     CONSTITUTION: A layer of high purity silicon 36,200μm thick is attached to part of the inside wall of an alumina cap 32 of a package. Most of the alpha particles released from the cap 32 which contain a plenty of impurities are absorbed by the high purity silicon layer 36, so that the probability that the alpha particles will reach MOS memory pellets 35 is quite little. Any alpha particles reaching the MOS memory rellets 35 must have consumed most of their energy on the way. Thus a memory device with the least probavbility of malfunctioning can be obtained. The high  purity silicon layer 36 may be substituted by germanium or the like metal, and such  layer may cover the inside walls of the package in their entirety in order to obtain  more effective results.

The light absorptive exothermic layers 2 generate heat and the guide grooves for tracking are melted to generate deformation when said layers are irradiated by semiconductor laser light from the substrate 1 side. The heat of the exothermic layers 2 is simultaneously transferred to the thermally shrinkable layers 3, by which said layers are shrink in volume and the guide grooves for tracking are shallowed and widened in the groove width. The pollution-free optical disk having high reliability is thus obtd.
