摘要 深入研究了Cl2基气体电感耦合等离子体(ICP)刻蚀系统对于GaN材料侧壁倾角的控制以及刻蚀速率的影响。通过调整ICP离子源功率、射频功率、气体流量、腔室压力等参数,经实验验证,实现了从23°~83°侧壁倾角的大范围工艺控制,为GaN基器件工艺提供了有益指导。 Sidewall profiles and etch rate of dry etched GaN mesas were investigated by using a chlorine based inductively coupled plasma (ICP) system. The process conditions were carefully selected by changing ICP ion source power, RF power, gas flow, and chamber pressure. The ex-perimental results show that a very wide sidewall profile angle could be achieved from 23°to 83° at certain optimized conditions, which provide a helpful process guideline for fabricating GaN based devices.
