Because the domestic Hi-Tech industry develops fast in recent years, so a lot of processes with key technology need studying and developing including the wafer foundry or LCD industry, and even thin film solar cell industry. But the main problem that the requisite components (such as heater module, susceptor, shower head module, turbo-molecule vacuum pump, etc.) are almost from original factory but Taiwan is few. Because of the reason and one of the new government's policies is for environmental protection and green energy industry developing, we try to develop our own technology in Taiwan.

近年来因国内高科技产业快速发展，所以许多制程与关键技术也陆续被投入大量研发，但不论是半导体产业或者平面显示器产业，乃至於薄膜太阳能电池产业，在设备研发上存在极大的问题，大部份关键零组件的取得皆源自国外母厂(例如加热模组、气体扩散模组、涡轮分子帮浦等元件)，所以缺乏自主设计研发能量，也因此许多关键制程技术无法充分发挥。
