Abstract

The present invention relates to processes for fabrication of Vertical MISFET devices or a stack of several of such devices. The Vertical MISFET device comprises a highly doped drain region, a non or lowly doped channel region and a source region forming a heterojunction with the channel region. The source region comprises a lowly doped part which contacts the channel region and a highly doped part which contacts the lowly doped part.
