Method for making an island of material confined between electrodes, and application to transistors

摘要

The invention relates to a method for producing a microstructure comprising an island (30) of material confined between two electrodes (32) forming barriers; the island of material having lateral flanks running parallel and perpendicular to the barriers, characterized in that the lateral flanks of the island are defined by etching of at least one layer (16), called the template layer, and the barriers are formed by damascening. Application to manufacturing of transistors and memories.
