Job title

Sub-30 nm sample preparation and limited-angle STEM tomography H/F

Subject

Prepare sub-30-nm FIB lamellae and use limited-angle STEM tomography to reduce projection effects in nanoscale semiconductor devices.

Contract duration (months)

6

Job description

As semiconductor devices become smaller and more complex, structural information from 2D STEM images becomes harder to interpret because projection effects and overlapping features through conventional FIB lamellae can obscure nanoscale structures.

The internship will improve both sample preparation and STEM characterization. Lamellae thinner than 30 nm will be prepared using FIB milling followed by low-energy argon-ion polishing.

Limited-angle electron tomography will then reconstruct the central slice of the FIB lamella to reduce projection effects. The results will be compared with a full 3D volume reconstructed using deep-learning approaches.

Methods / Means

Electron microscopy (FIB-SEM, STEM), deep-learning approaches
