Abstract

See full text

A sensing apparatus includes a device containing microwells and a switched capacitor circuit in which at least one of the sensing/storage capacitors is a capacitor that extends perpendicularly with respect to a semiconductor device layer containing field effect transistors. Capacitor structures extend into microwells or within a doped layer on a handle substrate. Ion generation within the microwells is sensed using the circuit.
