摘要:
Device structures with hyper-abrupt p-n junctions, methods of forming hyper-abrupt p-n junctions, and design structures for an integrated circuit containing devices structures with hyper-abrupt p-n junctions. The hyper-abrupt p-n junction is defined in a SOI substrate by implanting a portion of a device layer to have one conductivity type and then implanting a portion of this doped region to have an opposite conductivity type. The counterdoping defines the hyper-abrupt p-n junction. A gate structure carried on a top surface of the device layer operates as a hard mask during the ion implantations to assist in defining a lateral boundary for the hyper-abrupt-n junction.

Disclosed is a Zener diode having a scalable reverse-bias breakdown voltage (Vb) as a function of the position of a cathode contact region relative to the interface between adjacent cathode and anode well regions. Specifically, cathode and anode contact regions are positioned adjacent to corresponding cathode and anode well regions and are further separated by an isolation region. However, while the anode contact region is contained entirely within the anode well region, one end of the cathode contact region extends laterally into the anode well region. The length of this end can be predetermined in order to selectively adjust the Vb of the diode (e.g., increasing the length reduces Vb of the diode and vice versa). Also disclosed are an integrated circuit, incorporating multiple instances of the diode with different reverse-bias breakdown voltages, a method of forming the diode and a design structure for the diode.

摘要:
A varactor diode includes a portion of a top semiconductor layer of a semiconductor-on-insulator (SOI) substrate and a gate electrode located thereupon. A first electrode having a doping of a first conductivity type laterally abuts a doped semiconductor region having the first conductivity type, which laterally abuts a second electrode having a doping of a second conductivity type, which is the opposite of the first conductivity type. A hyperabrupt junction is formed between the second doped semiconductor region and the second electrode. The gate electrode controls the depletion of the first and second doped semiconductor regions, thereby varying the capacitance of the varactor diode. A design structure for the varactor diode is also provided.
