CALLING ALL FUTURE EXPERTS IN lithographic nanostructuring! YOU WANT TO DEMONSTRATE YOUR HIGH INNOVATIVE POTENTIAL AND IMPRESS US WITH YOUR IDEAS? POSTS ARE IMMEDIATELY AVAILABLE FOR
Bachelor-/Master-/Diplom thesis work: Nanostructuring for integrated circuit applications

Starting from 01.09.2019 an exciting student position in the field of lithographic nanostructuring is available. Micro- and Nanostructuring plays an essential role in the semiconductor manufacturing process. It implies both lithography and etch processes which are interdependent and should be precisely optimised for each specific application.

The focus of a current project will be nanostructuring for interconnects in the 22 FDX technology. The smallest distance required by this application is around 40 nm. This dimension is not directly reachable by the 193 nm immersion lithography used in the semiconductor foundries. Hence alternative approaches should be applied, as well as lithography and etch processes should be developed and optimised. At Fraunhofer IPMS e-beam lithography is used for investigation purposes due to its flexibility.

The tasks of the current thesis are:

  • Development and adjustment of e-beam lithography processes for different stacks, which are relevant for 22 FDX technology
  • Layout data preparation for e-beam exposure
  • Investigation of the process window (variation of the process parameters, such as resist thickness and resist bake temperature)
  • Characterisation of the resulting nanostructures using mainly CD-SEM (alternatively cross section SEM, AFM) and evaluation of the measurement results

Was Sie mitbringen


  • You already finished or due to finish your Bachelor degree in physics, chemistry, electrical engineering or material science
  • You have gained good knowledge in the area of semiconductor manufacturing processes, ideally lithography
  • You are able to handle and evaluate large amounts of measurement data (in Excel, Origin or Matlab)
  • Ideally you have already some experience of working in the lab with organic chemicals
  • Fluent English
  • Was Sie erwarten können
