Abstract

PURPOSE:To enable to attain automatic recognition and automatic production of a minute size semiconductor device by making informations of a large quantity to be held in a minute area by a method wherein dot type recesses and projections are formed at a part of the surface of an element chip to express a code according to the recesses and the projections thereof. CONSTITUTION:Element pellets 2 are formed reticulately in a semiconductor wafer 1 to form gate arrays, for example. The element pellet 2 thereof is constructed with bits 5 to indicate the kind of itself and other informations at a part of the surface formed with circuit elements 3 and electrode pads 5, etc. The bits 5 thereof consist of minute recess parts 6 formed in length and width, and arrangement of the minute recess parts 6 are differed to each other in accordance with contents of the respective informations.
