ABSTRACT:
In the fabrication process of the integrated circuit manufacturing there used to be an inconvenience in handling the many of the cassette of the wafers. By using the color coded cassette of the present invention the personnel can distinguish and identify the correct status of the wafers in the cassette in the fabrication process. The personnel can sort and transport the wafers in the cassette depending on the status of the process shown in the color code. The color coding cassette of the present invention employs several colors for coding on the side of the cassette. The change and display of the proper color code are operated by the handy knobs attached to each color coding piece. The colors are differently painted from every other color to distinguish itself from every other code. They are green, white, yellow and red, for example. This color coding technology can be embodied by injection moulding of the plastic. It cost less expenditure. The valuable utilization can be found in the integrated circuit fabrication in the manufacturing and in the research and development.
