    摘要: An electrostatic discharge (ESD) protection structure is disclosed. The ESD protection structure comprises an active device. The active device includes a plurality of drains. Each of the drains has a contact row and at least one body contact row. The at least one body contact row is located on the active device in a manner to reduce the amount of voltage required for triggering the ESD protection structure. A system and method in accordance with the present invention utilizes a LDNMOS transistor as ESD protection element with optimised substrate contacts. The ratio of substrate contact rows to drain contact rows is smaller than one in order to reduce the triggering voltage of the inherent bipolar transistor.

    摘要: An ESD protection circuit includes semiconductor structures as basic elements whose electrical conductivity changes in a breakdown or avalanche manner in the presence of an applied voltage which exceeds a threshold value. The ESD protection circuit has a matrix of basic elements in which a desired current capacity can be set by specifying a number of basic elements in each row, and a desired voltage capacity can be set by specifying a number of rows.

    摘要: By aligning the primary flat of a wafer with a (100) plane rather than a (110) plane, devices can be formed with primary currents flowing along the (100) plane. In this case, the device will intersect the (111) plane at approximately 54.7 degrees. This intersect angle significantly reduces stress propagation/relief along the (111) direction and consequently reduces defects as well as leakage and parasitic currents. The leakage current reduction is a direct consequence of the change in the dislocation length required to short the source-drain junction. By using this technique the leakage current is reduced by up to two orders of magnitude for an N-channel CMOS device.
