发明名称 Optical membrane singulation process utilizing backside and frontside protective coating during die saw
摘要 A process for singulating MOEMS optical devices from a precursor structure, in which the precursor structure comprises device material, having movable optical structures, and handle material, through which optical ports are formed to provide for optical access to the movable optical structures. The process comprises coating a frontside and a backside of the precursor structure with protection material. The precursor structure is then attached to a substrate such as dicing tape and the precursor structure separated into individual optical devices by a process, including die sawing. Thereafter, the optical devices are removed from the tape and the protection material removed from the optical devices.
