Patent ID: 8732923

Claim:
A method for manufacturing an acoustic wave device comprising: adhering a wafer-shaped first piezoelectric substrate having a first acoustic wave device thereon to a front face of a first adhesive sheet and dividing the first piezoelectric substrate into rectangles; adhering a wafer-shaped second piezoelectric substrate having a second acoustic wave device thereon to a front face of a second adhesive sheet and dividing the second piezoelectric substrate into rectangles; adhering a third adhesive sheet to the first piezoelectric substrate from an opposite side of the first adhesive sheet and moving at least one divided portions of the first piezoelectric substrate selectively to the third adhesive sheet; adhering a fourth adhesive sheet to the second piezoelectric substrate from an opposite side of the second adhesive sheet and moving at least one divided portions of the second piezoelectric substrate selectively to the fourth adhesive sheet; moving the first piezoelectric substrate on the first adhesive sheet to the fourth adhesive sheet by adhering the fourth adhesive sheet having the second piezoelectric substrate adhered selectively thereon to a front face of the first piezoelectric substrate on the first adhesive sheet; and moving the second piezoelectric substrate on the second adhesive sheet to the third adhesive sheet by adhering the third adhesive sheet having the first piezoelectric substrate adhered selectively thereon to a front face of the second acoustic wave device on the second adhesive sheet.
