Abstract:
(EN) Methods of forming germanium channel structure are described. An embodiment includes forming a germanium fin on a substrate, wherein a portion of the germanium fin comprises a germanium channel region, forming a gate material on the germanium channel region, and forming a graded source/drain structure adjacent the germanium channel region. The graded source/drain structure comprises a germanium concentration that is higher adjacent the germanium channel region than at a source/drain contact region.
(FR) La présente invention concerne des procédés de formation d'une structure de canal de germanium. Un mode de réalisation consiste à former un bloc de germanium sur un substrat, une partie du bloc de germanium comprenant une région de canal de germanium, à former un matériau de grille sur la région de canal de germanium et à former une structure source/drain à paliers adjacente à la région de canal de germanium. La structure source/drain à paliers présente une concentration en germanium qui est plus grande en un lieu adjacent à la région de canal de germanium qu'au niveau d'une région de contact de source/drain.
