Abstract
A semiconductor wafer and a method for forming a semiconductor. The semiconductor wafer includes: a first semiconductor component having a first device; a second semiconductor component having a second device; an insulation layer laterally extending to the first semiconductor component and the second semiconductor component; and a grind layer configured on or adjacent to a backside of the semiconductor wafer. Therefore, chipping or cracking can be decreased or avoided when the grind layer is exposed during the thinning process (such as backside grinding).
