- 摘要:
- 铝互连工艺结束后检查晶圆表面发现大片残留缺陷，通过成分分析确认其为光刻胶。对镀膜、光刻、腐蚀、去胶工序进行工艺排查后发现改变镀膜工艺可以改善光刻胶残留情况。实验结果证明铝薄膜表面形貌与光刻胶残留现象密切相关。减小薄膜表面粗糙度可以改善光刻胶残留现象。
- Abstract:
- Large residual defects were found on the surface of the wafer in aluminum interconnection process, which were confirmed as photoresist by component analysis. It was found that changing the coating process can improve the residual situation of photoresist by process inspections on coating, lithography, corrosion and removing of photoresist. The results show that the surface morphology of the aluminum film is closely related to the photoresist residual. The residuals can be improved by reducing the surface roughness of the film
