There is provided a method of making two electrically separated inductors using deposition and wet-etching techniques, which inductors are formed by interwinding one of the inductors within the other inductor on the same planar level. In still another aspect of the invention, there is provided a method of making various levels inductors, each level having at least two electrically separated inductors, using deposition and wet-etching techniques. The inductors on each planar level are formed by interwinding one of the inductors within the other inductor, and then stacking these in a preferred manner. In still another aspect, there is provided a manner of connecting together inductors formed according to the above methods in order to achieve various inductor configurations.

A semiconductor device is described that includes one or more electrostatic discharge (ESD) protection circuits. Each circuit comprises reverse-biased steering diodes connected in series between power rail and signal ground, a bypass Zener diode and a substrate Zener diode. The Zener diodes provide ESD protection and the steering diode cooperate with the substrate Zener diode to provide a bypass function that is substantially symmetric about the signal ground. Noise in the circuit can be shunted using internal and/or external capacitances that can be implemented as Zener diodes.

Monolithic multi-channel ESD protection device

The present invention relates to a low pass filter incorporating coupled inductors to enhance stop band attenuation. In one embodiment, the coupled inductors are provided along with various capacitors to provide for superior performance within a smaller surface area of a semiconductor or ceramic integrated device. In a further specific embodiment, the capacitors are formed on an integrated device within an area on which entirely intertwined inductors are formed. In another embodiment, at least one further pair of coupled inductors is included to create additional frequency attenuation notches, as well as a wide stop-band.
