Abstract
A method for forming a component of TMBS type having its periphery formed of a trench with insulated walls filled with a conductor, including the steps of depositing on a semiconductor substrate a thick layer of a first insulating material and a thin layer of a second material; simultaneously digging a peripheral trench and the trenches of the component; isotropically etching the first material so that a cap overhanging a recess remains; forming a thin insulating layer; and filling the trenches and said recess with a conductive material.
