	研究興趣與成果
Updated on September 3, 2006 個人研究以電漿物理及其應用為主。電漿是由電子，離子及中性粒子所組成。當帶電粒子密度夠高時，電漿會呈現集体性的行為，如波動等。同時由於電漿中的反應是許多不同成分間的作用(Heterogeneous Interactions), 其中包括紫外線，中性粒子，活化粒子，電子及離子的反應。尤其是包含了具能量的粒子，它們能引發許多特殊的化學與物理的反應。例如在電漿蝕刻技術中，正離子經由電漿鞘層(Plasma Sheath)加速後轟擊矽晶圓，使其表面原子的鍵結破壞進而能迅速與活化粒子進行化學反應達到蝕刻效果。另外如在鑽石膜成長中，電漿一方面產生成長所需要的碳原子，當其在表面形成鍵結時，電漿中所產生的氫原子則能與石墨鍵結的碳原子進行蝕刻反應而留下鑽石的鍵結。在奈米碳管成長中，電漿鞘層的電場則能達到高方向性的成長。這是其他方法所無法達到的。電漿的產生是利用電場加速電子，經由與氣体粒子的游離碰撞產生電子及離子。同時也經由非彈性碰撞產生活化粒子, 或解離分子產生原子。目前產生電漿的方法以使用的功率源而言有直流放電(DC discharge)，低頻及中頻放電 (數KHz到數MHz),射頻放電(13.6MHz)，及微波放電(2.45GHz)。現行電漿製程多操作在低氣壓之輝光放電(mTorr 到百Torr)。而操作在1大氣壓的低溫電漿製程則是現在研究的重要課題。以半導體製程而言，則以射頻放電被採用的最多。研究課題: 大面積微波表面波電漿及電漿共振電漿浸入離子佈植及電漿鞘層動態分柝電感偶合電漿加熱模式轉換均勻低溫大氣電漿源(表面介質放電，大氣電漿東)。鑽石膜，類鑽膜成長及尖狀結構成長，場發射研究單晶之奈米鑽鑽石柱及電子元件電漿東液晶配向
