    摘要： A dicing method for a micro electro mechanical system chip, in which a high yield and productivity of chips can be accomplished, resulting from preventing damage to microstructures during a dicing process by using a protective mask. The dicing method for a micro electro mechanical system chip, comprising the steps of designing a grid line and wafer pattern on a chip-scale on the non-adhesive surface of a transparent tape as a protective mask (first step); sticking microstructure-protecting membranes on the adhesive surface of the transparent tape (second step); putting the transparent tape on the whole surface of a wafer in a state wherein the grid line designed on the non-adhesive surface of the transparent tape is matched to the dicing line of the wafer (third step); cutting the transparent tape to a size larger than the wafer, mounting the wafer on a guide ring and dicing the wafer (fourth step); and separating the transparent tape from diced chips (fifth step).
