摘要 为探讨半导体激光电化学刻蚀的工艺特性,采用808 nm半导体激光作为光源,聚焦激光照射浸于溶液中的阳极上,实现激光诱导电化学刻蚀材料。在实验的基础上,通过对金属和半导体材料刻蚀的比较,分析了激光电化学刻蚀硅的工艺特点。实验表明,808 nm激光诱导电化学刻蚀工艺是一个光热刻蚀过程,但不适合刻蚀半导体材料。 Laser electrochemical etching process combining laser etching and electrochemical etching is a new etching technique. 808 nm semiconductor laser is used as light source. The experiments of micromachining materials by laser-induced electrochemical etching are carried out. On the basis of experiment, the character of laser electrochemical etching is analyzed in detail by comparing etching metal to semiconductor. In the experiment 808 nm laser electrochemical etching laser photo-thermal effect induces electrochemical dissolution. It is unsuitable for 808 nm laser electrochemical etching to etch semiconductor.
