摘要
通过对SU 8胶近紫外波段下透射光谱的分析,得到不同波长近紫外光在SU 8胶中的穿透深度,并分析了不同波段近紫外光对SU 8胶微结构的影响,结果表明穿透深度大的近紫外波段曝光出来的图形质量好,深宽比大,侧壁陡直。
The transmission spectrum of the SU-8 photoresist in the near UV is analyzed to get the penetration length of the different wavelengths UV in SU-8.The effect on the SU-8 microstructure for the different wavelengths UV is also analyzed.The results show that the pattern exposured by the near UV band of deep penetration has good quality,high aspect ratio and steep sidewall.
