Classification: G11B,H02N

Abstract:
A method for manufacturing a microintegrated structure comprising:forming interconnection regions in a substrate of semiconductor material; carrying out a first epitaxial growth, thereby forming a monocrystalline epitaxial region above the interconnection regions; forming lower sinker regions in said monocrystalline epitaxial region, in direct contact with said interconnection regions; forming insulating material regions on a structure portion of said monocrystalline epitaxial region; carrying out a second epitaxial growth, thereby forming a pseudo-epitaxial region comprising a polycrystalline portion above said structure portion and elsewhere a monocrystalline portion; and forming upper sinker regions in said polycrystalline portion of said pseudo-epitaxial region, in direct contact with said lower sinker regions.
