Abstract
The mask making is the first step in the semiconductor device manufacturing. It depends entirely upon mask delivery time whether it will take a short time or not to develop and produce the new devices. It is required to construct the system which can manage mask making and delivery quickly. It is very important to control the much various information on the many kinds of the mask for ASIC use quickly. It is also important to control the many various masks processing parameters, that is, to memorize the parameters and to use the appropriate parameters when the masks for general purpose device like a memory use are revised. The data base system to control the various information and parameters is requested from many mask makers and device ones. We have made a unitary data base including a large amount of information on the various ASIC devices and the various processing parameters of the memory devices, and information on the mask making progress, whereabouts of the masks. And we have constructed the new mask/reticle making control system using with the database.
