Discrete semiconductors, such as photo diodes and other analog chips, are spreading their application areas with increasing tendency of small-volume-many-types production style. In such chips, the circuit pattern design can be rather simple and often designed by general purpose 2D CAD systems such as AutoCAD. The key in the design work, however, is in improving the quality in deciding the specification and in smoothening the manufacturing process. It is the primary target for designers to understand the customer needs right, and to get better preparation for production.

Especially, the customer communication is important since it enables designers to join to the customer's projects in earlier timing, thus enables them to provide better technical offers.
