摘要： A circuit is provided which prevents dendrite formation on interconnects during semiconductor device processing due to a dendrite-forming current. The circuit includes a switch located in at least one of the dendrite-forming current paths. The switch is configured to be open or in the “off” state during processing, and is configured to be closed or in the “on” state after processing to allow proper functioning of the semiconductor device. The switch may include an nFET or pFET, depending on the environment in which it is used to control or prevent dendrite formation. The switch may be configured to change to the “closed” state when an input signal is provided during operation of the fabricated semiconductor device.

摘要： The present invention provides a varactor that has increased tunability and a high quality factor Q as well as a method of fabricating the varactor. The method of the present invention can be integrated into a conventional CMOS processing scheme or into a conventional BiCMOS processing scheme. The method includes providing a structure that includes a semiconductor substrate of a first conductivity type and optionally a subcollector or isolation well (i.e., doped region) of a second conductivity type located below an upper region of the substrate, the first conductivity type is different from said second conductivity type. Next, a plurality of isolation regions are formed in the upper region of the substrate and then a well region is formed in the upper region of the substrate. In some cases, the doped region is formed at this point of the inventive process. The well region includes outer well regions of the second conductivity type and an inner well region of the first conductivity type. Each well of said well region is separated at an upper surface by an isolation region. A field effect transistor having at least a gate conductor of the first conductivity type is then formed above the inner well region.
