| 摘 要： | 采用反应离子刻蚀(RIE)技术,对EPG 535光刻胶和碲锌镉(CZT)基体刻蚀工艺进行研究,采用原子力显微镜(AFM)法测试CZT基体刻蚀前后的表面质量,探讨了EPG 535光刻胶刻蚀速率和CZT基体表面粗糙度的影响因素。结果表明,当RF功率为60 W、氧气气压为1.30 Pa、氧气流量为40 cm3/min,光刻胶达到最大刻蚀速率;随着RF功率降低,刻蚀后CZT基体的表面粗糙度降低。实验优化的刻蚀参数为:RF功率40 W、氧气气压1.30 Pa、氧气流量40 cm3/min。

| Abstract: | EPG 535 photoresist and CdZnTe substrate were etched respectively by means of O2 reactive ion etching(RIE) technique.The surface roughness of CdZnTe substrate were detected by atomic force microscope(AFM).The effects of RF power,O2 pressure and the flux of O2 rate on etching rate of EPG 535 photoresist and the surface roughness of CdZnTe substrate were explored.The results showed that the etching rate was up to extremum when RF power was 60 W,O2 pressure was 1.30 Pa and the flux of O2 was 40 cm3/min.Surface... |
