Abstract
Description
einen höheren Übertragungsleitwert, eine geringere parasitäre Kapazität, die Vermeidung von Auswirkungen durch Dotiermittelschwankungen und verbesserte Kurzkanaleigenschaften. Außerdem werden gute Kurzkanaleigenschaften in Kanälen erreicht, die kürzer als 20 nm sind, wobei im Kanalbereich kein Dotiermittel erforderlich ist. Dadurch werden die Tunnelungunterbrechungs- (tunneling break-down), die Dotiermittelquantisierungs- und Störstellenprobleme (impurity scattering), die mit der Kanaldotierung verbunden sind, gelöst.
