Fabrication methods for bi-directional silicon controlled rectifier device structures. A well of a first conductivity type is formed in a device region, which may be defined from a device layer of a semiconductor-on-insulator substrate. An anode of a first silicon controlled rectifier is formed in the first well. A cathode of a second silicon controlled rectifier is formed in the first well. The anode of the first silicon controlled rectifier has the first conductivity type. The cathode of the second silicon controlled rectifier has a second conductivity type opposite to the first conductivity type.
摘要:
An approach for cancelling reverse reflections in very-fast transmission line pulse (VFTLP) testing of an electrostatic discharge (ESD) device in a semiconductor is provided. A method includes generating an incident pulse in a VFTLP system for applying to a device under test (DUT). The method also includes generating a delayed replica of the incident pulse. The method also includes cancelling a portion of a reverse reflection of the incident pulse by combining the delayed replica with the reverse reflection at a power divider.
