Abstract: IC devices including inductors or transformers formed based on BPRs are disclosed. An example IC device includes semiconductor structures of one or more transistors, an electrically conductive layer, a support structure comprising a semiconductor material, and an inductor. The inductor includes an electrical conductor constituted by a power rail buried in the support structure. The inductor also includes a magnetic core coupled to the electrical conductor. The magnetic core includes magnetic rails buried in the support structure, magnetic TSVs buried in the support structure, and a magnetic plate at the backside of the support structure. The magnetic core includes a magnetic material, such as Fe, NiFe, CoZrTa, etc. In some embodiments, the IC device includes another power rail that is buried in the support structure and constitutes another electrical conductor coupled to the magnetic core. The two power rails and magnetic core can constitute a transformer.

Abstract: IC devices including semiconductor devices isolated by BSRs are disclosed. An example IC device includes a first and a second semiconductor devices, a support structure, and a BSR. The BSR defines boundaries of a first and second section in the support structure. At least a portion of the first semiconductor device is in the first section, and at least a portion of the second semiconductor device is in the second section. The first semiconductor device is isolated from the second semiconductor device by the BSR. Signals from the first semiconductor device would not be transmitted to the second semiconductor device through the support structure. The BSR may be connected to a TSV or be biased. The IC device may include additional BSRs to isolate the first and second semiconductor devices. An BSR may be a power rail used for delivering power.

Abstract: Methods for providing fill patterns for IC devices are disclosed. An example method includes detecting a first device and a second device in an image, e.g., a two- or three-dimensional image representing the IC device. A line is defined based on the devices. The line divides the image into a first section and a second section. A first structure is generated based on the first device. A second structure is generated based on the second device. The second structure is a mirror image of the first structure across the line. A first fill pattern is generated in the first section based on the first structure. A second fill pattern is generated in the second section based on the first fill pattern, e.g., through a reflection transformation of the first fill pattern across the line. The two fill patterns represent patterns of fill structures to be included in the IC device.

Abstract: IC devices including transmission lines are disclosed. An example IC device includes two electrically conductive layers (first and second layers) and a support structure between the two electrically conductive layers. The first layer is coupled to transistors over or at least partially in the support structure. A shield of a transmission is placed in the first layer. Conductors of the transmission line are placed in the second layer and are coupled to the first layer by TSVs. Another example IC device includes three electrically conductive layers (first, second, and third layers). The first layer is coupled to transistors over or at least partially in the support structure. A shield of a transmission line is placed in the second layer and conductors of the transmission line are placed in the third layer. The conductors are coupled to the first layer by TSVs and coupled to the second layer by vias.
