    摘要: A controlled seam magnetic core lamination utilizable in an inductor structure includes a magnetic base and first and second spaced-apart magnetic sidewalls extending substantially orthogonally from the base to define a seam therebetween. The controlled seam magnetic core lamination is utilizable in an inductor structure that includes: a non-conductive lower mold; a plurality of spaced-apart controlled seam lower laminations formed in the lower mold, each magnetic lower lamination having a horizontal base and first and second spaced-apart sidewalls extending substantially vertically upward from the base to define a seam therebetween; a non-conductive isolation layer formed on the lower mold and the magnetic lower laminations; a conductive trace formed on the isolation layer; a non-conductive upper mold formed over the isolation layer and the conductive trace; and a plurality of spaced-apart controlled seam magnetic upper laminations formed in the upper mold, each magnetic upper lamination having a horizontal base and first and second spaced-apart sidewalls that extend substantially vertically upward from the base to define a seam therebetween.

    摘要: A method for forming a capacitive micromachined ultrasonic transducer (CMUT) is provided that includes forming oxide features outwardly of a CMUT control chip in a silicon wafer. The oxide features are planarized. A silicon-on-insulator (SOI) wafer is bonded to the planarized oxide features. For a particular embodiment, the SOI wafer comprises a single crystal epitaxial layer, a buried oxide layer and a silicon layer, and the single crystal epitaxial layer is bonded to the planarized oxide features, after which the silicon layer and the buried oxide layer of the SOI wafer are removed, leaving the single crystal epitaxial layer bonded to the oxide layer.

    摘要: Multiple wafers that each has multiple high-precision circuits and corresponding trim control circuits are batch trimmed in a process where each wafer is formed to include openings that expose trimmable circuit elements that are internal to the circuitry of the high-precision circuits. The high-precision circuits and trim control circuits are electrically activated during the trimming phase by metal traces that run along the saw streets. The method attaches a wafer contact structure to each wafer to electrically activate the metal traces. The method places the wafers with the wafer contact structures into a solution where the exposed trimmable circuit elements are electroplated or anodized when the actual output voltage of a high-precision circuit does not match the predicted output voltage of the high-precision circuit.

    摘要: An on-chip inductor structure for a DC-DC power regulator circuit merges the switching transistor metallization with the inductor. Thick top level conductor metal that is used to strap the transistor array and to lower its on-state resistance is also used to extend the power inductor into the transistor array. Thus, the structure includes three basic components: a power inductor that spirals around the transistor array, the transistor array itself, and the transistor array metallization that is used to form a distributed inductance situated over the transistor array.
