METHOD FOR PROTECTING LENS OF CHARGE COUPLED DEVICE IN ASSEMBLY PROCESS.

摘要

PURPOSE: A method for protecting lens of charge couples device in an assembly process is provided to protect a micro lens from particles by forming a protective layer on a substrate. CONSTITUTION: A protective layer(30) is formed on a substrate(10) formed with a flattened layer(20), a color filter(22), and a micro lens(28). The protective layer(30) is used in order to protect a damage of a light receiving region. A wafer is cut according to each chip by cutting a scribe line. The protective layer(30) is removed. The protective layer(30) is formed with a solvent containing a PGMEA(Propylene Glycol Monomethyl Ether Acetate) series or a DGDE(Diethylene Glycol Dimethyl Ether) series.
