A depletion-mode LDMOS device is in the semiconductor surface layer including a source, drain, and a gate above a gate dielectric, and a channel region under the gate on the gate dielectric. A drift region is between the channel region and the drain, wherein the drain also provides a cathode for the lateral junction diode device. An embedded diode includes a second cathode and an anode that is shared with the device. The embedded diode is junction isolated by an isolation region located between the anode and the source. The anode and isolation region are directly connected to the gate and the second cathode is directly connected to the source.

Abstract: An integrated circuit is formed on a substrate containing a semiconductor material having a first conductivity type. A deep well having a second, opposite, conductivity type is formed in the semiconductor material of the first conductivity type. A deep isolation trench is formed in the substrate through the deep well so as separate an unused portion of the deep well from a functional portion of the deep well. The functional portion of the deep well contains an active circuit element of the integrated circuit. The separated portion of the deep well does not contain an active circuit element. A contact region having the second conductivity type and a higher average doping density than the deep well is formed in the separated portion of the deep well. The contact region is connected to a voltage terminal of the integrated circuit. An integrated circuit is formed on a substrate containing a semiconductor material having a first conductivity type.

Abstract: Embodiments of the invention are directed to a system, method, or computer program product for creating channel accessible single function micro services used for light analytics. The micro services are built as small transferable modules to be a single function high efficiency small module. The micro services are generated for a specific single function, then deployed at an interface lever and stored to an associate device at any communication channel associated with an entity. The micro services require specific programming and are generated for a specific data collection process light analytics function. The micro services translate the extracted data into a readable format and transmit, via secure communication network, the translated data to a custom build database for subsequent light analytics framework implementation.
