发明名称 Method of fabricating semiconductor device
摘要 A method of fabricating a semiconductor device includes forming a first chip separating groove such that its depth is less than the total depth of the wafer, forming a first metallization layer inside the first chip separating groove, thinning the wafer, forming a second chip separating groove in a region opposite the first chip separating groove of the rear surface of the wafer so that the wafer is separated into a plurality of semiconductor chips, forming metallization layer inside the second chip separating groove, forming a PHS layer on the entire rear surface of the wafer, and cutting the wafer at the chip separating groove, thereby producing a semiconductor device. The burr produced when the wafer is cut does not protrude from the rear surface of the wafer, assuring good adhesion between the semiconductor chip and a chip carrier, realizing a semiconductor device of a good heat dispersion characteristic and, therefore, of high reliability.
