摘要:
A method for packaging a semiconductor device. The method includes: providing a dielectric layer over the semiconductor device; determining patterns and placement of material on the dielectric layer to provide a predetermined magnetic or electric effect for the device, such effects being provided on the device from such patterned and placed material solely by electrical or magnetic waves coupled between such material and the device; and forming the material in the determined patterns and placement to provide the predetermined effects.

A variable attenuator having: an input port; a semiconductor device having a control electrode for controlling carriers flowing between a first electrode and a second electrode, such control electrode being coupled to one of the first and second electrodes, one of the first and second electrodes being coupled to the input port and the other one of the first and second electrodes being coupled to a reference potential to form an active device characterized by such device having a resistivity in the device to the flow of carriers substantially constant when such device is fed through input port with a signal having a relatively small power level and having a resistivity in the device to the flow of carriers which is nonlinear when such device is fed through input port with a signal having a relatively large power level; and an output port coupled to one of the first and second electrodes coupled to the input port. Such a network may be used with a power amplifier to reduce excessive small signal gain and soft compression.

A MMIC having: a substrate; a plurality of active and passive electrical elements disposed on a top surface of the substrate; a plurality of coplanar waveguide transmission line sections disposed on the top surface of the substrate for electrically interconnecting the active and passive electrical elements; an electrical conductor disposed on a bottom surface of the substrate under the coplanar waveguide section. Edges of ground plane conductors of the coplanar waveguide (CPW) sections have slots therein in regions thereof connected to the active and passive devices. The design of such circuit includes mathematical models of the CPW with the pair of local ground planes and the strip conductor thereof have relatively narrow connectable ports.
