Abstract
A method for efficiently producing circuit patterns (semiconductor devices) that allows for effortless pickup of circuit patterns after dicing. The method includes producing a semiconductor substrate with circuit patterns formed on a first surface; forming a first laminate by bonding a first support through a first adhesive layer to the first surface; forming a second laminate by bonding a second support through a second adhesive layer having a dot pattern to a second surface opposite to the first surface; debonding the first support from the second laminate; and picking up the circuit patterns from the second support.
