The GE manufacturing standard and processing technology was introduced and employed by RUNAU Electronics since 1980s. The complete manufacturing and testing condition were completely coinciding?with the requirement of USA market requirement. As a pioneer of manufacturing thyristor in China, RUNAU Electronics had provided the art of state power electronics devices to USA, European countries and global users. It’s highly qualified and appraised by the clients and more big wins and value were created for partners.
The thyristor chip manufactured by RUNAU Electronics is sintered alloying technology employed. The silicon and molybdenum wafer was sintered for alloying by pure aluminum (99.999%) under high vacuum?and high temperature environment. The administration of sintering characteristics is the key factor to affect the quality of thyristor. The know-how of RUNAU Electronics in addition to manage the alloy junction depth, surface flatness, alloy cavity as well full diffusion skill, ring circle pattern, special gate structure. Also the special processing was employed to reduce the carrier life of the device, so that the internal carrier recombination speed is greatly accelerated, the reverse recovery charge of the device is reduced, and the switching speed is improved?consequently. Such measurements were applied to optimize the fast switching characteristics,?on-state characteristics,?and?surge current?property. The performance and conduction operation of thyristor is reliable and efficient.
By strict controlling of flatness and parallelism?of molybdenum wafer and external package, the chip and molybdenum wafer will be integrated with external package tightly and completely. Such will optimize the resistance of surge current and high short circuit current. And the measurement of electron evaporation technology?was employed to create a thick aluminum film on silicon wafer surface, and ruthenium?layer plated on molybdenum surface will enhance thermal fatigue resistance?greatly, the work life time of fast switch thyristor will be increased significantly.
