Abstract:
1. A non-contact identification semiconductor device comprising: a bendable paper or bendable film-form medium; a semiconductor chip inserted into said bendable paper or bendable film-form medium, said semiconductor chip including means for receiving an inquiry to the non-contact identification semiconductor device, a memory for storing identification information of multiple bits and means for sending and said identification information of multiple bits; an antenna coupled to said semiconductor chip to receive said identification information of multiple bits from said semiconductor chip and to transmit said identification information outside of said non-contact identification semiconductor device; and means for reducing stress concentration on said semiconductor chip during bending of said bendable paper or bendable film-form medium, wherein said means for reducing stress concentration comprises forming said semiconductor chip to have a long side length not greater than 0.5 mm in plane dimension.
