A PCB bridge for interconnection of two or more semiconductor chips for data communication between the semiconductor chips includes a plurality of metal strips; and a dielectric material disposed in between the plurality of metal strips. The PCB bridge is employed in a vertical direction in a semiconductor module for interconnection of two or more semiconductor chips, the vertical direction of the PCB bridge provides a flexible impedance matching by adjusting the dielectric material and a trace width of the PCB bridge, and the vertical direction of the PCB bridge avoids signal reflections by matching the impedance to a source, and a trace length of the PCB bridge is limited by spacing in between two semiconductor chips which further limited inductance of the trace of the PCB bridge.

Architecture for chip-to-chip interconnection in semiconductors

The present invention provides an insulated-gate bipolar transistor (IGBT) structure and a method for manufacturing the same. The structure is a planar IGBT structure, and is characterized by an ultra-thin channel and buried oxide located below the channel. The structure can provide the theoretically lowest on-state voltage drop.
