An apparatus and method for wafer level fabrication of high value inductors directly on top of semiconductor integrated circuits. The apparatus and method includes fabricating a semiconductor wafer including a plurality of dice, each of the dice including power circuitry and a switching node. Once the wafer is fabricated, then a plurality of inductors are fabricated directly onto the plurality of dice on the wafer respectively. Each inductor is fabricated by forming a plurality of magnetic core inductor members on an interconnect dielectric layer formed on the wafer. An insulating layer, and then inductor coils, are then formed over the plurality of magnetic core inductor members over each die. A plated magnetic layer is formed over the plurality of inductors respectively to raise the permeability and inductance of the structure.

System and method for forming a cloud appliance. The system includes a management server, an artifact repository, a continuous integration server, and build managers. The management server includes source code and a project script for forming the cloud appliance. The artifact repository stores artifacts required to build the cloud appliance and artifacts that comprise the built cloud appliance. The continuous integration server manages a build process, unit test process, and deployment process based on the project script. The build managers build the source code for customizing the virtual machine and store the built source code as the second artifacts in the artifact repository. The continuous integration server instantiates the virtual machine from template and customizes the virtual machine to form a customized virtual machine using the artifacts specified in the project script, a customization process for each of the artifacts based on a type of the artifact.

A capacitive micromachined ultrasonic transducer (CMUT), which has a conductive structure that can vibrate over a cavity, has a number of vent holes that are formed in the bottom surface of the cavity. The vent holes eliminate the deflection of the CMUT membrane due to atmospheric pressure which, in turn, allows the CMUT to receive and transmit low frequency ultrasonic waves.

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.

A method includes forming first isolation trenches in a first side of a first semiconductor-on-insulator (SOI) structure to electrically isolate multiple portions of the first SOI structure from each other. The method also includes bonding a second SOI structure to the first SOI structure to form multiple cavities between the SOI structures. The method further includes forming conductive plugs through a second side of the first SOI structure and forming second isolation trenches in the second side of the first SOI structure around the conductive plugs. In addition, the method includes removing portions of the second SOI structure to leave a membrane bonded to the first SOI structure. The isolated portions of the first SOI structure, the cavities, and the membrane form multiple capacitive micromachined ultrasonic transducer (CMUT) elements. Each CMUT element is formed in one of the isolated portions of the first SOI structure and includes multiple CMUT cells.

Various apparatuses and methods for forming integrated circuit packages are described. One aspect of the invention pertains to an integrated circuit package in which one or more integrated circuits are embedded in a substrate and covered with a layer of photo-imageable epoxy. The substrate can be made of various materials, including silicon, quartz and glass. An integrated circuit is positioned within a cavity in the top surface of the substrate. The epoxy layer is formed over the top surface of the substrate and the active face of the integrated circuit. An interconnect layer is formed over the epoxy layer and is electrically coupled with the integrated circuit.
