Abstract: Instabilities and related drawbacks that arise when interruptions of a perimetral high voltage ring extension implanted regions (RHV) of a main junction (P_tub 1, (P_tub2, …) of an integrated device must be realized may be effectively prevented. This important result is achieved by an extremely simple expedient: whenever an interruption (I) of the high voltage ring extension must be created, it is not realized straight across it along a common orthogonal direction to the perimetral implanted region, on the contrary, the narrow interruption is defined obliquely or slantingly across the width of the perimetral high voltage ring extension. In case of a straight interruption, the angle of slant (α) may be generally comprises between 30 and 60 degrees and more preferably is 45 degrees or close to it. Naturally, the narrow interruption is created by masking it from dopant implantation when realizing the perimetral high voltage ring extension region.

Abstract: The disclosure is directed to wide band-gap semiconductor devices, such as power devices based on silicon carbide or gallium nitride materials. A power device die is attached to a carrier substrate or a base using sintered silver as a die attachment material or layer. The carrier substrate is, in some embodiments, copper plated with silver. The sintered silver die attachment layer is formed by sintering silver nanoparticle paste under a very low temperature, for example, lower than 200° C. and in some embodiments at about 150° C., and with no external pressures applied in the sintering process. The silver nanoparticle is synthesized through a chemical reduction process in an organic solvent. After the reduction process has completed, the organic solvent is removed through evaporation with a flux of inert gas being injected into the solution.

Abstract: A supply node receives supply voltage and an output node provides a regulated output voltage to a load. A switching transistor is coupled between the supply and output nodes. The switching transistor is controlled by a drive signal generated by a control circuit to control switching activity. The control circuit includes circuitry to sense a feedback voltage indicative of the regulated output voltage and a comparator generating a comparison logic signal dependent on a comparison of the feedback voltage to a reference. A logic circuit generates a skip signal in response to the comparison logic signal. A counter generates a termination signal. Signal processing circuitry controls the switching activity by asserting the drive signal as a function of the skip signal and the termination signal.

Abstract: A circuit includes an electronic switch configured to be coupled intermediate a high-voltage node and low-voltage circuitry and configured to couple the low-voltage circuitry to the high-voltage node. A voltage-sensing node is configured to be coupled to the high-voltage node via a pull-up resistor. A further electronic switch can be switched to a conductive state to couple the voltage-sensing node and the control node of the electronic switch. A comparator compares a threshold with a voltage at the voltage-sensing node and causes the further electronic switch to switch on in response to the voltage at said voltage-sensing node reaching said threshold. A charge pump coupled to the current flow-path of the electronic switch is activated to the conductive state to pump electric charge from the current flow-path of the electronic switch to the control node of the electronic switch via the further electronic switch switched to the conductive state.
