Due to that it’s necessary to rely on analytical dependencies or produce sample lots while designing devices according to special requirements of the customers. However production of samples leads to substantial increase of lead time, and in some cases it’s even impossible to do. Usage of analytical dependencies while solving this question can lead to unexpected results. Developing flexible production adapted to certain requirements of the customers, these factors should be totally excluded.
That is why on a certain development stage of production of power semiconductor electronics necessity in additional tool occurred, which made possible:
- Quickly and efficiently analyze dependences of characteristics of devices on technological features of their production, departure from technological process and operating modes;
- Get an idea of physical processes happening in semiconductor element and changes of main physical values in time.
At the moment such tool is computer instrumentally technological modeling, which became available due to rapid development of computers.
