∑ Micro-electronics Institute (∑Institute) found since June 1998, research and produce the micro-electrical-device and other related electrical technology. We have already succeeded in the developing about the semiconductor sensor, which is used in the automatic field, and the ultra-low-voltage shottky, which is used in the new generation power switch. Now the products above will be quantity produced soon. The market of these two kinds of devices is very large. 1-10 billion devices are used very year over world. The profit is extremely huge. Next step, ∑Institute will develop micro-electrical-circuit and micro-system; for example, instant-frequency-inspection receiver, missile-carrying signal disturber etc. that is used in the military electrical battle.
