Abstract:
1. A method for producing a field effect device comprising a source output line of a first metallic interconnection level connected to a source contact arranged on a source electrode, a drain output line of the first metallic interconnection level connected to a drain contact arranged on a drain electrode, and a gate output line of the first metallic interconnection level connected to a gate contact arranged on a gate electrode, the method comprising the following successive steps: forming an insulating layer on a dielectric layer, forming an etching mask on the insulating layer, the etching mask simultaneously laterally delineating at least the gate electrode, the source contact, the drain contact, the source output line, the drain output line and the gate output line so as to obtain self-alignment of the gate electrode, the source contact, the drain contact, the source output line, the drain output line and the gate output line, the simultaneous lateral delineation substantially defining the lateral borders of each of the gate electrode, the source contact, the drain contact, the source output line, the drain output line and the gate output line, masking the source output line, the drain output line and the gate output line in the etching mask, delineating the gate electrode, the source contact and the drain contact in the insulating layer by means of the etching mask, depositing a gate material forming at least the gate electrode, forming the source contact and the drain contact at least in the insulating layer, and forming the source output line, the drain output line and the gate output line of the first metallic interconnection level in the etching mask.
