Claim:
1. A method for producing a semiconductor device, comprising: providing, above a substrate on which a first contact portion is formed, a lower shield plate that extends in a first direction and includes a magnetic substance so that the lower shield plate avoids the first contact portion; placing, above the lower shield plate, a plurality of semiconductor chips each having a second contact portion at predetermined intervals in the first direction so that the first contact portion and the second contact portion correspond to each other; electrically connecting the first contact portion and the second contact portion by using a connection member; placing, above the semiconductor chips, an upper shield plate that extends in the first direction and includes a magnetic substance so that the upper shield plate avoids the second contact portion and the connection member; forming a block by sealing the lower shield plate, the semiconductor chips, the connection member, and the upper shield plate by using a resin; cutting the lower shield plate and the upper shield plate by forming, in the block, a first groove extending in a second direction intersecting with the first direction so that the first groove avoids the semiconductor chips; forming, in the first groove, a side shield member that connects the lower shield plate and the upper shield plate and includes a magnetic substance; and separating the semiconductor chips by cutting the block so that the side shield member is separated in the first direction.
