Latest Patents

Macdougall's latest patents include advancements in high voltage integrated circuits and Hall-cell technology. The first patent describes high voltage integrated circuit field plates that are connected directly to epitaxial pockets. These plates are formed simultaneously with high resistivity polysilicon resistors and are insulated from crossover metal by a dual insulation of silicon dioxide and silicon nitride. This innovation allows for the formation of MNS capacitors that have a higher packing density than their MOS counterparts, making them both space-wise and process-wise compatible with the polysilicon field plates.

The second patent focuses on an integrated circuit with an ion implanted Hall-cell. This Hall-cell is designed to have relatively high sensitivity and low power consumption, situated in an isolated epitaxial pocket of an integrated circuit. The epitaxial layer is of opposite conductivity type to that of the supporting silicon substrate. This design allows for closely controlled electrical properties while imposing few restraints on the quality of other components in the integrated circuit.
