Described examples include sensor apparatus and integrated circuits having a package structure with an internal cavity and an opening that connects of the cavity with an ambient condition of an exterior of the package structure, and an electronic sensor structure mechanically supported by wires in the cavity and including a sensing surface exposed to the cavity to sense the ambient condition of an exterior of the package structure.

Electronic sensors with sensor die in package structure cavity

An integrated force sensing element includes a piezoelectric sensor formed in an integrated circuit (IC) chip and a strain gauge at least partially overlying the piezoelectric sensor, where the piezoelectric sensor is able to flex. A human-machine interface using the integrated force sensing element is also disclosed and may include a conditioning circuit, temperature gauge, FRAM and a processor core.

Piezoelectric sensor apparatus

In described examples, an integrated circuit includes a leadframe structure, which includes electrical conductors. A first coil structure is electrically connected to a first pair of the electrical conductors of the leadframe structure. The first coil structure is partially formed on a semiconductor die structure. A second coil structure is electrically connected to a second pair of the electrical conductors of the leadframe structure. The second coil structure is partially formed on the semiconductor die structure. A molded package structure encloses portions of the leadframe structure. The molded package structure exposes portions of the first and second pairs of the electrical conductors to allow external connection to the first and second coil structures. The molded package structure includes a cavity to magnetically couple portions of the first and second coil structures.

A method of forming, and a resulting, an integrated circuit wave device. The method (i) affixes an integrated circuit die relative to a substrate; (ii) creates a form relative to the integrated circuit die and the substrate; and (iii) forms a wave shaping member having a shape conforming at least in part to a shape of the form.

In described examples, an apparatus includes: an integrated circuit die having multiple terminals; the integrated circuit die positioned on a die pad portion of a leadframe having leads for external connections, at least some of the leads having an inner portion electrically coupled to at least one terminal of the integrated circuit die; a fuse element coupled between one of the leads of the leadframe and at least one terminal selected from the multiple terminals of the integrated circuit die; and encapsulation material surrounding the integrated circuit die and the leadframe to form a packaged integrated circuit including the integrated circuit die and the fuse element, and having a cavity in the encapsulation material surrounding the fuse element such that the fuse element is spaced from the encapsulation material.

Integrated circuits with a molded package including a cavity and a semiconductor die spaced from an interior surface of the molded package within the cavity. The semiconductor die includes one or more electrical components, a thermal control component to control the temperature of the electrical component, and a driver to provide a current or voltage signal to the thermal control component at least partially according to a setpoint signal.

Integrated circuits with thermal isolation and temperature regulation

An integrated circuit package that comprises a lead frame, an integrated circuit located on the lead frame and a shunt resistor coupled to the integrated circuit. The shunt resistor has a lower temperature coefficient of resistance than the lead frame, and the lead frame has a lower resistivity than the shunt resistor. The shunt resistor has a low-resistance coupling to external leads of the lead frame, or, the shunt resistor has its own integrated external leads.
