Abstract

The method according to the invention is directed to manufacturing an electric device (100) according to the invention, having a body (102) with a resistor comprising a phase change material being changeable between a first phase and a second phase, the resistor having a first electrical resistance when the phase change material is in the first phase, and a second electrical resistance different from the first electrical resistance when the phase change material is in the second phase. The resistor is a nanowire (NW) electrically connecting a first conductor (172, 120) and a second conductor (108, 121). The method comprises the step of providing a body (102) having the first conductor (172, 120), providing the first conductor (172, 120) with the nanowire (NW) thereby electrically connecting the nanowire (NW) and the first conductor (172, 120), and providing the nanowire (NW) with the second conductor (108, 121) thereby electrically connecting the nanowire (NW) and the second conductor(108, 121).

Description

technical field [0001] The invention relates to a method of manufacturing an electrical (pneumatic) device having a body with a resistor comprising a phase change material that can change between a first phase (phase) and a second phase (phase) , the resistor electrically connects the first conductor and the second conductor. The resistor may have a first resistance when the phase change material is in the first phase and a second resistance different from the first resistance when the phase change material is in the second phase. [0002] The invention also relates to such electrical (pneumatic) devices. Background technique [0003] US5933365 discloses a method in which the substrate is provided with an electrical contact layer 32 and a conductive heating layer 34, all in figure 1 A is shown. On top of these layers, pores 46 are formed into the dielectric layer, thereby exposing the heating layer 34 . The dielectric layer and air holes are then provided with a memory m...
