Polichromatic image sensor with microlenses for stereoscopic acquisition

摘要

This paper presents the fabrication of microlenses forintegration on a stereoscopic image sensor in CMOS technologyand a low-cost technology for fabricating optical filters arraystuned for the primary colors. The material selected forfabricating the microlens was the AZ4562 positive photoresistand the fabrication process explained. Moreover, the fabricationprocess presented in this paper is for directly printing the opticalfilters into a transparent flexible substrate (acetate).
