An apparatus includes a first drain/source region and a second drain/source region surrounded by an isolation ring formed over a substrate, the isolation ring formed being configured to be floating, and a first diode connected between the substrate and the isolation ring, wherein the first diode is a Schottky diode.

An electrical fuse (e-fuse) includes a fuse link including a silicided semiconductor layer over a dielectric layer covering a gate conductor. The silicided semiconductor layer is non-planar and extends orthogonally over the gate conductor. A first terminal is electrically coupled to a first end of the fuse link, and a second terminal is electrically coupled to a second end of the fuse link. The fuse link may be formed in the same layer as an intrinsic and/or extrinsic base of a bipolar transistor. The gate conductor may control a current source for programming the e-fuse. The e-fuse reduces the footprint and the required programming energy compared to conventional e-fuses.

A biological-electrode protection module is a monolithic component including a capacitor and a voltage-limiting component integrated in a common substrate. The capacitor component is connected in the series path between the input and output terminals. The voltage-limiting component is connected between ground and a node in the series path. The voltage-limiting component has a low breakdown voltage no greater than 6 volts and may be a biphasic device operating in the punch-through mode. Moreover, the protection module is connected to or integrated with a set of biological electrodes at a distance no greater than 1 cm. The capacitor may be a 3D capacitor, and common fabrication processes may be used in forming the voltage-limiting component and the capacitor. A JFET may be integrated in the same substrate so that an electrical signal output from the monolithic protection device is already pre-amplified.

The first portion includes a first well doped with a first type forming the channel of the MOS transistor and two first regions doped with a second type opposite to the first type that are arranged in the first well which form the source and drain of the MOS transistor. The first portion further includes: a second well doped with the second type that is arranged laterally with respect to the first well to form the base of the bipolar transistor; a second region doped with the first type that is arranged in the second well to form the emitter of the bipolar transistor; and a third region doped with the first type that is arranged under the second well to form the collector of the bipolar transistor.
