Abstract: A vertical power component includes a semiconductor substrate, a first electrode in contact with a lower surface of the substrate, and a second electrode in contact with an upper surface of the substrate. The vertical component is mounted to a metal connection plate via a metal spacer. The metal spacer includes a lower surface soldered to the metal connection plate and an upper surface soldered to the first electrode of the vertical power component. The metal spacer is made of a same metal as the metal connection plate. A surface are of the metal spacer mounted to the first electrode is smaller than a surface area of the first electrode.

Abstract: A capacitor has a variable capacitance settable by a bias voltage. A method for setting the bias voltage including the steps of: (a) injecting a constant current to bias the capacitor; (b) measuring the capacitor voltage at the end of a time interval; (c) calculating the capacitance value obtained at the end of the time interval; (d) comparing this value with a desired value; and (e) repeating steps (a) to (d) so as long as the calculated value is different from the set point value. When calculated value matches the set point value; the measured capacitor voltage is stored as a bias voltage to be applied to the capacitor for setting the variable capacitance.

Abstract: A triac has a vertical structure formed from a silicon substrate having an upper surface side. A main metallization on the upper surface side has a first portion resting on a first region of a first conductivity type formed in a layer of a second conductivity type. A second portion of the main metallization rests on a portion of the layer. A gate metallization on the upper surface side rests on a second region of the first conductivity type formed in the layer in the vicinity of the first region. A porous silicon bar formed in the layer at the upper surface side has a first end in contact with the gate metallization and a second end in contact with the main metallization.
