Electronic device, and method of manufacturing an electronic device

摘要

An electronic device (100), the electronic device (100) comprising a substrate (101), a convertible structure (102) arranged on and/or in the substrate (101), being convertible between at least two states by heating and having different electrical properties in different ones of the at least two states, wherein the convertible structure (102) has a first portion having a first width (w1), and has a second portion having a second width (w2), the second width (w2) being smaller than the first width (w1), and a protrusion (108) protruding through the convertible structure (102) to thereby narrow the second portion of the convertible structure (102) from the first width (w1) to the second width (w2).

主权项

1. An electronic device, the electronic device comprising
a substrate; a convertible structure arranged on or in the substrate and arranged between two electrodes for providing path for current to flow from one to the other of the two electrodes, the convertible structure being convertible between at least two states by heating and having different electrical properties in different ones of the at least two states, wherein the convertible structure has a first portion having a first width, and has a second portion having a second width, the second width being smaller than the first width; a protrusion protruding through the convertible structure configured and arranged to narrow the second portion of the convertible structure from the first width to the second width by way of the second portion constricting an intermediate section of the current path in the convertible structure and between the two electrodes;
wherein the convertible structure is a thermo-dependent structure, particularly a phase change structure which is convertible between at least two phase states, and further including an electric sensing circuit configured and arranged for sensing electrical properties of the convertible structure and for switching between different ones of said at least two states; andwherein the convertible structure is electrically conductive between the two electrodes in at least one in the at least two states, and wherein except for the second portion, the path for current to flow from one to the other of the two electrodes is provided uniformly by the first width.
