Latest Patents

One of Christoph Zeller's latest patents is a circuit with a sensor and non-volatile memory featuring a ferroelectric dielectric capacitor. This circuit includes a sensor that delivers a charge, a capacitor that non-volatilely stores the charge, and a read and reset circuit that reads out the stored charge. The capacitor is designed with additional connection terminals linked to the read and reset circuit, which operates in parallel with the sensor terminals. The sensor can be a photodiode, phototransistor, Hall sensor, or thermoelement. A switch, preferably a transistor, is connected between one of the additional terminals and one of the sensor terminals, driven by a dedicated drive circuit. The sensor and capacitor are integrated within a semiconductor body, and during the storage procedure, the timing of the switch is coordinated to maintain an electrical field below the saturation point of the ferroelectric dielectric.

Another notable patent involves the formation of silicided junctions in deep submicron MOSFETs through defect enhancement. This process begins with a silicon wafer that undergoes precleaning with hydrofluoric acid. Following this, the wafer is transferred to a cobalt sputtering tool for low-energy bombardment with Ar+ ions, creating an ultra-shallow damage region. Cobalt metal is then deposited at room temperature, resulting in the formation of a CoSi2 layer in the diffusion window.
