Laser induced diffusion is a technology that dope the impurities into a certain region of semiconductor by a focused laser. it has the advantages of “ low temperature processing ” and ” direct writing ”, and it is promising to use this technology in the fabrication of monolithically optoelctronic integrated circuits ( oeics ) to solve the incompatibility problem between optoelctronic and electronic components
激光誘導擴散是用聚焦的激光束局域加熱半導體基片，將雜質以擴散的方式摻入到特定區域並且達到一定要求的一種技術，具有「低溫處理」 、 「直接寫入」 、 「局域升溫」等獨特優點，可有效解決單片光電集成器件（ oeics ）中光、電兩部分的工藝兼容這一難題。 -
Some previous experiments have showed that cavities had more efficient gettering than p - diffusion, mechanical damage and ion implantation. most of studies about cavities gettering are concentrated on the peculiarity of cavities gettering metal impurities intentionally into silicon wafer from the viewpoint of basic study. this technique especially applied to low - contamination process, how ever, has not been carefully studied, which should be important to the semiconductor manufacturing
而過去的工作多集中在從基礎研究的角度研究氦微孔對有意摻入金屬雜質的矽片的吸除特性，對無意引入的低濃度金屬雜質的器件吸雜效果的研究卻非常少，這方面的研究是氦微孔技術走向實際應用的必經之路。
