Abstract

A semiconductor substrate includes excavations which form trenches sunk. A capacitive element includes: a first dielectric envelope conforming to sides and bottoms of the trenches; a first semiconductor layer conforming to a surface of the first dielectric envelope in the trenches; a second dielectric envelope conforming to a surface of the first semiconductor layer in the trenches; and a second semiconductor layer conforming to a surface of the second dielectric envelope in the trenches.
