Abstract
A method for manufacturing a semiconductor device includes forming protruded electrodes on a plurality of chip areas of a semiconductor wafer having the chip areas and boundary regions both being provided in a surface of the semiconductor wafer; forming a surface-side protective member so as to cover the surface of the semiconductor wafer and the protruded electrodes removing the semiconductor wafer corresponding to the boundary regions and forming trenches which expose the surface-side protective member; forming a back-side protective member with which the trenches are filled and which covers the back of the semiconductor wafer; and dividing the semiconductor wafer in the boundary regions with widths thinner than those of the trenches in such a manner that the surface-side protective member and the back-side protective member charged into the trenches are left in cut sections.
