    Abstract: The present disclosure relates to a method for manufacturing electronic chips comprising, in order: a. forming metal contacts on the side of a first face of a semiconductor substrate, in and on which a plurality of integrated circuits have been previously formed; b. depositing a first protective resin on the metal contacts and the first face of the semiconductor substrate; c. forming first trenches of a first width on the side of a second face of the semiconductor substrate; d. depositing a second protective resin in the first trenches and on the second face of the semiconductor substrate; e. forming second trenches of a second width, less than the first width, opposite the first trenches up to the metal contacts; and f. forming third trenches opposite the second trenches, the third trenches extending through the metal contacts.

    Abstract: An electronic device includes a base substrate with a mica substrate thereon. A top face of the mica substrate has a surface area smaller than a surface area of a top face of the base substrate. An active battery layer is on the mica substrate and has a top face with a surface area smaller than a surface area of a top face of the mica substrate. An adhesive layer is over the active battery layer, mica substrate, and base substrate. An aluminum film layer is over the adhesive layer, and an insulating polyethylene terephthalate (PET) layer is over the aluminum film layer. A battery pad is on the mica substrate adjacent the active battery layer, and a conductive via extends to the battery pad. A conductive pad is connected to the conductive via. The adhesive, aluminum film, and PET have a hole defined therein exposing the conductive pad.

    Abstract: A circuit includes two input nodes and two output nodes. A rectifier bridge is coupled to the input and output nodes. The rectifier bridge includes a first and second thyristors and a third thyristor coupled in series with a resistor in series. The series coupled third thyristor and resistor are coupled in parallel with one of the first and second thyristors. The first and second thyristors are controlled off, with the third thyristor controlled on, during start up with resistor functioning as an in in-rush current limiter circuit. In normal rectifying operation mode, the first and second thyristors are controlled on, with the third thyristor controlled off.

    Abstract: A method for manufacturing electronic chips includes depositing, on a side of an upper face of a semiconductor substrate, in and on which a plurality of integrated circuits has been formed, a protective resin. The method includes forming, in the protective resin, at least one cavity per integrated circuit, in contact with an upper face of the integrated circuit. Metal connection pillars are formed by filling the cavities with metal. The integrated circuits are separated into individual chips by cutting the protective resin along cut lines extending between the metal connection pillars.
