An integrated inductor is formed on an integrated circuit or other substrate. The inductor is formed of a stack of almost totally enclosed rings of conductive material in which each ring has a single gap. Vias connect adjacent rings on opposite sides of their gaps so as to form a coil shaped structure. The inductor has applications in filtering, in an oscillator, in an antenna, combined with an active detection circuit, combined with an electron source, in a microelectromechanial systems or MEMS, or the like. The inductor may be formed in a vertical orientation or in a horizontal orientation. Chemical mechanical polishing may be used for planarizing layers.

Integrated inductor in semiconductor manufacturing

An improved wafer scale integrated circuit is described which includes non-contact power and data transmission coupling. Wireless power and data coupling reduces the mechanical stresses and strains on the wafer, and makes better use of the wafer area. An additional benefit comes from allowing better heat transfer management. In one embodiment, power is provided by inductive coupling. Data flow into and out of the wafer is accomplished optically, using optical detectors to receive and light emitting diodes to transmit. Multiple devices are integrated onto the semiconductor wafer. Systems may be incorporated using the traditional die sites. Connections between systems are made in the space between die sites.

Method and apparatus for a wafer level system

The present invention provides an integrated circuit chip having one or more circuit elements that perform a desired circuit function with the circuit elements being encompassed by a molding compound that forms a package for the chip. The molding compound has a capacitance associated with it. The integrated circuit chip includes a second integrated circuit element within the molding compound in which the second integrated circuit element monitors the molding compound to detect a change in capacitance in the molding compound resulting from a removal of a portion or all of the molding compound. In response to a detection of a change in capacitance, the second integrated circuit element alters the desired circuit function provided by the other integrated circuit elements.

A method and structure for sensing data such as temperature with respect to objects such as silicon wafers undergoing fabrication or other processes involve the use of a monitor element of material and configuration similar to that of the objects being processed. A structure such as a closed loop or segment of a spiral may be formed on the surface of the monitor element, and acts as a secondary coil when brought into operative relation with a transformer structure which includes a primary coil, a current source and a sensing device. The sensing device senses variations in the electrical characteristics in the primary coil, caused by the presence of the monitor element, and can thereby determine the temperature or other desired data relating to the monitor element, which is substantially the same as comparable data for the objects being processed.

Structure and method for remotely measuring process data

A memory security device within a chip which employs a power source coupled to the memory. The power source produces a signal having a level sufficient to erase or destroy the memory when the chip is exposed to acid. The power source includes an electrolytic cell for producing a direct voltage output, and an electrolytic signal amplification circuit coupled between the electrolytic cell and the memory.
