Latest Patents

Friemann’s patent, “Device and Method for Inhibiting a Substrate Current in an IC Semiconductor Substrate,” describes devices and methods for preventing substrate current from being injected into the substrate of a CMOS circuit.

The invention detects the potential at a contact in the integrated CMOS circuit and compares it with a reference value. When the detected potential is at or below that value, the circuit connects the contact to a leakage-circuit node. This provides a path for discharging the current and helps prevent it from flowing to ground through a parasitic lateral bipolar structure. The leakage node may connect to the reference-potential line or to another line with a higher potential.
