Technologies for micro and nano systems

Prof. Dr. T. Geßner, Prof. Dr. K. Hiller

Forms of teaching and examination

The module is devided into lectures and tutorials (§ 4):

• L: Technologies for Micro and Nano Systems (2 LVS)
• T: Technologies for Micro and Nano Systems (2 LVS)

Classes are taught in English. The module ends with a final written exam (120 minutes). If you successfully passed the exam, you can award 5 credit points. The evaluation of the exam follows the examination regulations (§ 10). This module is offered once a year and has a duration of one semester.

Objectives and contents

Objectives are: understanding of technology steps and technology process flows for MEMS and NEMS components and systems, technologies for advanced MEMS and NEMS, technologies for system integration.
Contents:

• Si-based technologies (bulk, surface, high aspect ratio, thin film encapsulation)
• Technologies based on alternative materials (LIGA, polymer based process flows)
• Packaging and 3D integration technologies
• Measurement techniques for MEMS/NEMS
• Examples of Si MEMS (spectrometers, inertial sensors, RF MEMS, actuators)
• Examples of non-Si MEMS (large area tactile arrays, fluidic systems, lab on chip)
