Abstract
A semiconductor device (20) is formed on a substrate (21) that has first and second well regions (25, 26) formed at a surface (18) of the substrate. A control electrode (34) extends over the surface to activate a first channel (42) with a control signal (V14) for routing a current (IN) from a first node (13) of the semiconductor device to an edge (43) of the first well region. The control signal further activates a second channel (46) for routing the current from an edge (45) of the second well region to a second node (15) of the semiconductor device.
Claims20
A semiconductor device, comprising:
- a substrate having a surface for forming first and second well regions;
- and
- a control electrode extending over the surface of the substrate to activate a first channel with a control signal to route a first current from a first node of the semiconductor device to an edge of the first well region, and a second channel to route the first current from an edge of the second well region to a second node of the semiconductor device.
A semiconductor device, comprising:
- a semiconductor substrate having a first conductivity type;
- a first well region formed in the semiconductor substrate and having a second conductivity type;
- a second well region formed in the semiconductor substrate and having the second conductivity type;
- and
- a conductive material formed over the semiconductor substrate to extend from the first well region to the second well region, where a control signal applied to the conductive material enables a first conduction path for providing a current to an edge of the first well region, and a second conduction path for routing the current from an edge of the second well region.
A method of controlling a current, comprising the steps of:
- providing a substrate having first and second well regions;
- inverting the first well region with a control signal to route the current through a first channel to the substrate;
- and
- inverting the second well region with the control signal to route the current from the substrate through a second channel.
