摘要:
A battery includes multiple conductive battery plates and a complex electrolytic material located between the conductive battery plates. The battery also includes a conductive sensor wire located within the complex electrolytic material. The conductive sensor wire may be configured to generate a magnetic field within the complex electrolytic material based on an electrical signal flowing through the conductive sensor wire. The battery may further include a temperature sensor wire within the complex electrolytic material.

A battery includes multiple conductive plates and a permeable electrolytic material and an ion membrane located between the conductive plates. The battery also includes at least one wire located within one or more of the permeable electrolytic material and the ion membrane. The at least one wire can be configured to regulate a flow of ions through the ion membrane based on an electrical signal flowing through the at least one wire. The at least one wire could also be configured to generate a magnetic field within the permeable electrolytic material based on another electrical signal flowing through the at least one wire. The battery could further include a temperature sensor wire within the permeable electrolytic material.

In a SOI process, a high lateral voltage isolation structure is formed by providing at least two concentric dielectric filled trenches, removing the semiconductor material between the dielectric filled trenches and filling the resultant gap with dielectric material to define a single wide dielectric filled trench.

An on-chip inductor structure is formed as part of an integrated circuit structure. The integrate circuit structure includes a semiconductor substrate having a top side and a back side, integrated circuit elements formed on the top side of the substrate, a conductive interconnect structure formed in contact with the integrated circuit elements and a passivation layer formed over the integrated circuit elements. The inductor structure comprises a layer of photoimageable epoxy formed on the passivation layer, a conductive inductor coil formed on the layer of photoimageable epoxy and at least one conductive via that extends from the inductor coil to the interconnect layer to provide electrical connection therebetween. Additionally, a back side trench may be formed in the back side of the semiconductor substrate beneath the inductor coil.

In an on-chip transformer, external electromagnetic field influences are reduced by providing an isolation transformer having primary and secondary windings with a figure 8 configuration so that current induced by an external magnetic field is nulled.
摘要:
A photodetector detects the absence or presence of light by detecting a change in the inductance of a coil. The magnetic field generated when a current flows through the coil passes through an electron-hole generation region. Charged particles in the electron-hole generation region come under the influence of the magnetic field, and generate eddy currents whose magnitudes depend on whether light is absent or present. The eddy currents generate a magnetic field that opposes the magnetic field generated by current flowing through the coil.

A magnetic guard ring is provided to reduce the susceptibility of a transformer-based data transmission to an externally generated magnetic field. The guard ring structure comprises strategically placed pieces of ferrite material, such as NiFe, that surround the transformer and “steer” the external magnetic field away from the transformer.
摘要:
An apparatus and method for fabricating high value inductors embedded on semiconductor integrated circuit. The apparatus and method involve forming a conductor on the semiconductor substrate. Once the conductor is formed, a polymer material is provided on the substrate surrounding the conductor. The polymer material contains a ferromagnetic material so that the permeability of the polymer is greater than one. In various embodiments, the ferromagnetic material may be any one of a number of different high permeable materials such as iron oxide, zinc, manganese, zirconium, samarium (SA), neodymium (NA), cobalt, nickel or a combination thereof.
