Abstract:
A semiconductor device for transmitting a radio frequency signal along a signal line includes a signal line that extends along a principal axis. On one side of the signal line is a first dielectric, and on the opposite side of the signal line is a second dielectric. First and second ground lines are proximate to the first and second dielectrics, respectively, and the ground lines are approximately parallel to the signal line. The device has a transverse cross-section that varies along the principal axis.
Abstract:
A method and system for de-embedding an on-wafer device is disclosed. The method comprises representing the intrinsic characteristics of a test structure using a set of ABCD matrix components; determining the intrinsic characteristics arising from the test structure; and using the determined intrinsic characteristics of the test structure to produce a set of parameters representative of the intrinsic characteristics of a device-under-test (“DUT”).
Abstract:
An inductor in an integrated circuit comprises a conductive trace disposed over an insulating layer which overlies a semiconductor substrate of a first conductivity type and at least two deep wells of opposite conductivity type in the substrate underneath the track. In another embodiment, an inductor in an integrated circuit comprises a conductive trace disposed over an insulating layer which overlies a semiconductor substrate of a first conductivity type; a shallow trench isolation region formed in the substrate underneath the trace; and at least two deep wells of opposite conductivity type in the substrate underneath the shallow trench isolation region. The present invention also includes methods of manufacturing the aforementioned inductors.
Abstract:
A method of manufacturing a semiconductor device with raised source/drain. This method eliminates the problem which is often experienced when the shallow junction technique is applied, in which over-etching of the source/drain region during the contact etching and the salicide process can lead to current leakages. The improved method includes the steps of forming a buffer conductive blocks on the source/drain regions which increase the thickness of source/drain regions. A related semiconductor structure made by the method has a plurality of bi-flange shape side wall spacers by which the semiconductor structure not only elevates the doped regions, it also provides an improved capability to suppress the electric bridges between the gate electrode and source/drain regions, respectively.
