According to the spherical shell model of the plastically deformed domain presented by Hill, four yield points on the (0001) net plane of CdS are estimated by using two micro-indenters and by revealing two types of etch figures. The hollow crystals on the sinter produced at the higher temperature region reveal the asteroid-pattern as an etch figure, and the other hollow crystals on the wall of the reaction tube produced at the lower temperature region reveal the rosette-pattern as the etch figure. The main results obtained are as follows : (1) Using the micro-Vickers-indenter or the Rockwell-superficial-indenter, the yield point of the asteroid-pattern is estimated as 342 [MPa] or 362 [MPa], respectively. (2) Similarly, the yield point of the rosette-pattern is estimated as 297 [MPa] or 307 [MPa], respectively.
