Abstract
Abstract A clearing frame for a semiconductor component is provided to enable a sufficient positioning of a particle beam. The clearing frame has a higher electrical conductivity than the environment thereof. The clearing frame also enables the determination of the layer resistance of the implantation via the high-frequency loss resistance measurement free from contact and destruction. The clearing frame can be placed at a fixed external DC potential, for example source or drain potential and therefore side gating effects can be avoided.
