Abstract: A leadframe has a die pad area and an outer layer of a first metal having a first oxidation potential. The leadframe is placed in contact with a solution containing a second metal having a second oxidation potential, the second oxidation potential being more negative than the first oxidation potential. Radiation energy is then applied to the die pad area of the leadframe contacted with the solution to cause a local increase in temperature of the leadframe. As a result of the temperature increase, a layer of said second metal is selectively provided at the die pad area of the leadframe by a galvanic displacement reaction. An oxidation of the outer layer of the leadframe is then performed to provide an enhancing layer which counters device package delamination.

Abstract: A plastic material substrate has a die mounting location for a semiconductor die. Metallic traces are formed on selected areas of the plastic material substrate, wherein the metallic traces provide electrically-conductive paths for coupling to the semiconductor die. The semiconductor die is attached onto the die mounting location. The semiconductor die attached onto the die mounting location is electrically bonded to selected ones of the metallic traces formed on the plastic material substrate. A package material is molded onto the semiconductor die attached onto the die mounting location.

Abstract: A device for generating a control signal based on the linear movement of a linear member is provided. The device includes a linear member, a rotatable member, a first inertial measurement unit (IMU) coupled to the rotatable member and a second IMU having a fixed position. The device also includes a processing circuit which uses sensing signals from the IMUS to determine an attitude of the first IMU referenced to the second IMU and generate a control signal based on the attitude.

Abstract: An electronic device includes a circuit board that manages supply of electricity to the electronic device. The circuit board includes an integrated circuit and an external capacitor coupled to a supply terminal of the circuit board. During a startup operation of the integrated circuit, the integrated circuit supplies a first charging current to charge the capacitor to a supply voltage value. The circuit board includes a boost circuit that receives a portion of the first charging current and outputs a second charging current that augments charging of the capacitor. The second charging current is an amplification of the first charging current. The integrated circuit enables operation of the electronic device after the capacitor is charged to the supply voltage value.

Abstract: A manufacturing method of an electronic device includes: forming a drift layer of an N type; forming a trench in the drift layer; forming an edge-termination structure alongside the trench by implanting dopant species of a P type; and forming a depression region between the trench and the edge-termination structure by digging the drift layer. The steps of forming the depression region and the trench are carried out at the same time. The step of forming the depression region comprises patterning the drift layer to form a structural connection with the edge-termination structure having a first slope, and the step of forming the trench comprises etching the drift layer to define side walls of the trench, which have a second slope steeper than the first slope.

Abstract: A power MOSFET device includes an active area accommodating a first body region and a second body region having a first and, respectively, a second conductivity value. The second value is higher than the first value. A first channel region is disposed in the first body region between a first source region and a drain region, and the first channel region has and having a first channel length. A second channel region is disposed in the second body region between a second source region and the drain region, and the second channel region has and having a second channel length smaller than the first channel length. A first device portion, having a first threshold voltage, includes the first channel region, and a second device portion, having a second threshold voltage higher than the first threshold voltage, includes the second channel region.

Abstract: A time measurement includes a multiphase clock generator and a phase sampling circuit. The multiphase clock generator generates a sequence of a given number n of phase shifted clock phases, wherein one of the phase shifted clock phases represents a reference clock signal. The phase sampling circuit is configured to generate a phase value indicative of a number of fractions 1/n of the clock period of the clock phases elapsed between an edge of the reference clock signal and an instant when an asynchronous event signal is set. The phase sampling circuit includes first through fourth sub-circuits, which respectively generate or determine first through fourth control signals.
