Benefits of technology

This approach prevents dust generation, enables clean accommodation and mounting of semiconductor devices, and allows for accurate and efficient sorting and re-utilization of receptacles, improving the overall process efficiency.

Problems solved by technology

However, since the label is made of paper, there arises the problem that such dust-generating substances as paper powder, adhesive and ink are produced within the dustproof bag.
Recently, bare chip products of a so-called narrow pitch type having a narrow pitch between bump electrodes have been increasing, and at the time of accommodating such semiconductor chips in a tray, the generation of dust caused by paper label poses a serious problem.
In carrying semiconductor devices with use of such receptacles as trays or a tape-reel, the receptacles differ in shape according to manufacturers, giving rise to the problem that the sorting work for re-utilizing the receptacles is troublesome.

Abstract

A method for carrying a semiconductor device includes: (a) providing semiconductor devices each having a main surface, a back surface, and a plurality of external terminals; (b) providing a tray having a front surface, a rear surface, an electronic tag imbedded in the tray, first concaved portions formed on the front surface, second concaved portions formed on the rear surface, the electronic tag constituted by a non-contact recognition type chip having a memory circuit in which recognizable information is stored, a depth of the first concaved portion is deeper than a depth of the second concaved portion; (c) housing the semiconductor devices into the first concaved portions respectively in such a manner that the back surface of the semiconductor device being oppose to a bottom of the first concaved portion; and (d) carrying the tray with the semiconductor devices.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a Continuation application of U.S. application Ser. No. 10 / 770,581 filed on Feb. 4, 2004, claims priority to Japanese Patent Application 2003-076402filed on Mar. 19, 2003, the contents of which are hereby incorporated by reference into this application.BACKGROUND OF THE INVENTION [0002] The present invention relates to semiconductor device carrying, mounting and packing techniques, as well as a technique for re-utilizing receptacles. Particularly, the present invention is concerned with a technique which is effectively applicable to the improvement of dustproofness. [0003] In a carrier used to accommodate semiconductor chips as objects to be accommodated and carry them, plural (five for example) trays each accommodating semiconductor chips are stacked and a cover is applied onto the top tray, then a group of trays thus stacked are united using fixing means such as rubber ring or clip, and the thus-united tray group i...
