Abstract:
In order to meet the needs of the semi-conductor industry as it requires finer lithography nodes, a method of feedback control for scanning probe microscopy generates a microwave frequency comb of harmonics in a tunneling junction by irradiating the junction with mode-locked pulses of electromagnetic radiation. Utilizing power measurements within one or more harmonics, the tip-sample distance in the tunneling junction may be regulated for maximum efficiency and avoid tip crash when used with resistive samples. Optionally, no DC bias is required to use the method. Utilization of this method contributes to true sub-nanometer resolution of images of carrier distribution in resistive samples such as semi-conductors.

Claim (Index 1):
A method of sample characterization, the method comprising:\n placing a sample as an electrode proximate a tip electrode in a circuit, thereby forming a tunneling junction; irradiating the tunneling junction with pulsed electromagnetic radiation thereby creating a microwave frequency comb within the tunneling junction; measuring a power of at least one harmonic within the microwave frequency comb; and using the measured power of the at least one harmonic as a criterion to control a distance between the tip electrode and sample.
