Manufacture

 For production of bipolar power semiconductor devices - diodes and thyristors JSC «Proton-Electrotex» has a complete operation cycle, well-developed infrastructure, updated production lines, measuring equipment and production facilities for «green technologies».

  Nominally the whole operating cycle has four main stages which are detached into separate subdivisions at the enterprise:
- production of diffused semiconductor elements that includes silicon wafers polishing area, diffusion process area and lithographic processing area.
- production of elements with thermal compensator that includes alloy and evaporation processes, bevel polishing and bevel jet etching.
- semiconductor element measurement that includes measurement systems for determination of static and dynamic parameters in whole range of device operating temperature.
- assembling of disk, module and stud devices as well as power assemblies with heat-sinks on their basis including processes of semiconductor assembling and encapsulation itself and approval tests.

  All operating processes are organized in strict accordance with requirements of quality management system (ISO 9001) and environmental management (ISO 14001).

  The enterprise is very attentive to the requirements of its customers; therefore the process of device manufacturing is adapted to «order based» production: there is an opportunity to group devices according to parameters, to produce specialized wire connections, to manufacture devices with unique characteristics.

  There are also specialized operating reliability laboratories, the main purposes of which are performance of classification and periodic tests, reliability test and determination of device service limit as well as technical support rendering to the customers.

  For the purpose of process optimization, rational engagement and use of one or another production, human or financial resource, active implementation of ERPsystem is being carried out, incorporating as far as production is concerned, units of production process recording and resources dispatching control as well as planning unit.
