    摘要: 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.

    摘要: Electronic elements (44, 44′, 44″) having an active device region (46) and integrated passive device (IPD) region (60) on a common substrate (45) preferably include a composite dielectric region (62, 62′, 62″) in the IPD region underlying the IPD (35) to reduce electromagnetic (E-M) (33) coupling to the substrate (45). Mechanical stress created by plain dielectric regions (36′) and its deleterious affect on performance, manufacturing yield and occupied area may be avoided by providing electrically isolated inclusions (65, 65′, 65″) in the composite dielectric region (62, 62′, 62″) of a material having a thermal expansion coefficient (TEC) less than that of the dielectric material (78, 78′, 78″) in the composite dielectric region (62, 62′, 62″). For silicon substrates (45), non-single crystal silicon is suitable for the inclusions (65, 65′, 65″) and silicon oxide for the dielectric material (78, 78′, 78″). The inclusions (65, 65′, 65″) preferably have a blade-like shape separated by and enclosed within the dielectric material (78, 78′, 78″).
