Claim Text:
1. A method for manufacturing a semiconductor device, the method comprising steps of: adhering a support substrate to a first surface of a wafer using an adhesive, the wafer including a first scribe line and a second scribe line demarcating chip regions, the first scribe line extending along a first direction and the second scribe line extending along a second direction crossing the first direction; thinning the wafer adhered to the support substrate; forming a groove in the first scribe line excluding a region located in an outer peripheral portion of the wafer, the groove piercing the wafer from a second surface to the first surface to expose the adhesive, the second surface being opposite to the first surface; and removing the adhesive by immersing the wafer adhered to the support substrate in a solvent such that the solvent permeates into the groove.
