Abstract: An apparatus including an electrostatic discharge (ESD) protection device comprising a semiconductor having first, second and third regions arranged to form a transistor, wherein the first region is doped with a first impurity of a first conductivity type and is separated from the second region which is doped with a second impurity of a second conductivity type opposite the first type, and wherein a dimensional constraint of the regions defines an operational threshold of the ESD protection device. In one example, the separation between a collector and an emitter of a bipolar transistor defines a trigger voltage to cause the electrostatic discharge protection device to become conducting. In another example, a width of a bipolar transistor base controls a holding voltage of the electrostatic discharge protection device.

Abstract: Methods of forming a thin film are disclosed. One such method can include sputtering a target material to form a first thin film resistor and adjusting a parameter of deposition to modulate a property of a subsequently formed second thin film resistor. For instance, a substrate bias and/or a substrate temperature can be adjusted to modulate a property of the second thin film resistor. A temperature coefficient of resistance (TCR) and/or another property of the second thin film resistor can be modulated by adjusting the parameter of deposition. The target material sputtered onto the substrate can include, for example, a Cr alloy, a Ni alloy, SiCr, NiCr, or the like. A relationship can be established between the substrate bias and/or substrate temperature and the thin film resistor property, and the relationship can be used in selecting deposition conditions for a desired property value.
