Patent ID: 7591071

Claim:
A manufacturing method for manufacturing semiconductor devices by cutting a silicon substrate having the semiconductor devices formed thereon, said method comprising: a step of forming a linear recess in the silicon substrate between adjacent semiconductor devices; an electrode forming step of forming, on an inner surface of the linear recess, an electrode for external electrical connection of one of the semiconductor devices; and a step of separating the one semiconductor device from at least one of the adjacent semiconductor devices on the silicon substrate by cutting the silicon substrate along the linear recess, wherein said electrode forming step includes a step of forming a metal thin film astride a cutting line at which the silicon substrate is to be cut, a step of forming a resist layer and patterning the resist layer on the metal thin film to remove at least one portion of the resist layer, a step of growing metal at the at least one portion, and a step of removing the patterned resist layer and the metal thin film below the patterned resist layer, wherein the electrode for external electrical connection is provided by the metal grown in the step of growing the metal.
