Patent ID: 6979592

Claim:
A method for fabricating a semiconductor apparatus comprising: forming a semiconductor integrated circuit on a first surface of a semiconductor substrate; forming a base member of insulating material on the first surface of the semiconductor substrate; forming a conductive layer directly on the first surface of the semiconductor substrate, the conductive layer being connected to the semiconductor integrated circuit and having an extended portion that extends onto a top surface of the base member; placing the first surface of the semiconductor substrate having the semiconductor integrated circuit, the base member and the conductive layer thereon as facing a connection substrate; connecting the extended portion of the conductive layer to the connection substrate; and supplying a sealing member in a space between the semiconductor substrate and the connection substrate, after said connecting, the base member and the sealing member having a same thermal expansion coefficient, the conductive layer is formed so that the extended portion extends onto an entirety of the top surface of the base member.
