Abstract: A diode structure fabrication method. In a P? substrate, an N+ layer is implanted. The N+ layer has an opening whose size affects the breakdown voltage of the diode structure. Upon the N+ layer, an N? layer is formed. Then, a P+ region is formed to serve as an anode of the diode structure. An N+ region can be formed on the surface of the substrate to serve as a cathode of the diode structure. By changing the size of the opening in the N+ layer during fabrication, the breakdown voltage of the diode structure can be changed (tuned) to a desired value.

Abstract: A structure for improving the electrostatic discharge robustness of an integrated circuit having an electrostatic discharge (ESD) device and a receiver network connected to a pad by interconnects. The interconnect between the pad and the ESD device has a high-k material placed adjacent to at least one surface of the interconnect and extending over the thermal diffusion distance of the interconnect. The high-k material improves the critical current density of the interconnect by increasing the heat capacity and thermal conductivity of the interconnect. The high-k material can be placed on the sides, top and/or bottom of the interconnect. In multiple wire interconnects, the high-k material is placed between the wires of the interconnect. A low-k material is placed beyond the high-k material to reduce the capacitance of the interconnect. The combination of low-k and high-k materials provides an interconnect structure with improved ESD robustness and low capacitance that is well suited for an ESD device.

Abstract: A scatter-implant process and device is provided where a bi-level doping pattern is achieved in a single doping step. Additionally, devices having different breakdown voltages can be produced in a single implant process. The scatter-implant is fabricated by scattering implant ions off the edge of a mask, thereby reducing the ion energy causing the ions to doping shallower regions than the non-scattered ions which dope a lower region. By adjusting various parameters of the doping process such as, for example, ion type, ion energy, mask type and geometry, in a position of scattering edge relative to other structure of the device, the scatter-implant can be tuned to achieve certain properties of the semiconductor device. Additionally, circuits can be made using the scatter-implant process where pre-selected portion of the circuit incorporate the scatter-implant region and other portions of the circuit do not rely on the scatter region.
