Abstract: A semiconductor device, such as a RF LDMOS, having a ground shield that has a pair of stacked metal layers. The first metal layer extends along the length of the semiconductor device and is formed on the upper surface of the semiconductor device body. The first layer has a series of regularly spaced apart lateral first slots. The second metal layer, coextensive with and located above the first metal layer, has a series of regularly spaced apart lateral second slots. The second slots overlie the spaces between the first slots, and the continuous portions of the second metal layer overlie the first slots. The slots are substantially parallel to wires extending over the ground shield. The ground shield is not limited to only two metal layers. The ground shield has a repeating unit design that facilitates automated design.

Abstract: A method for transferring data between a first computer and a second computer. The first computer sends a first request to the second computer in a first connection. The first request includes a request to start a session, an encrypted ID of the session, and an encrypted hash value for information in the first request. The information in the first request comprises the request to start the session and the encrypted session ID. The second computer receives the first request, and as a result, decrypts the encrypted hash value in the first request, independently determines a hash value for the information in the first request and compares the independently determined hash value to the decrypted hash value. If there is match, the second computer starts a session with the first computer. Subsequently, the first computer sends a second request to the second computer in a second connection in the session.
