DEPARTMENT Microelectronics and Nanoelectronics

 
DESCRIPTION This study-unit covers classification of microsensors, applications, benefits of microsensors including scaling laws. The unit then also presents an overview of MEMS fabrication processes and materials, lithography and etching; silicon and polymer-based processes; electrical and mechanical properties of MEMS devices: electrical and thermal conductivity, stress and strain, stiffness matrix, bending of beams, torsional deflection, spring constant and mechanical resonance.

The study-unit also covers fluid-based MEMS: fluid mechanics concepts, lab-on-CD technology, dispensers, flow control, valves, hydrophobic and hydrophilic surfaces, electrostatic actuation, SAW actuation.

Furthermore, issues of processing analogue and digital output signals from micro and nanosensors, as well as interfacing of micro and nanosensors are also presented. Levels of integration (circuit level, MEMS level, microsystem level, SoC and SiP) are also discussed.

An introduction to Tanner Tools/Coventorware software for MEMS design is also covered.

Study-unit Aims:

This unit aims at:
- training students in quantitative analysis and design techniques for various types of MEMS devices ranging from beam structures to microfluidic devices for applications such as switches, varactors and filters;
- training students on the issues of interfacing MEMS devices to the rest of an integrated embedded system.

Learning Outcomes:

1. Knowledge & Understanding:
By the end of the study-unit the student will be able to:

- understand the underlying principles and fabrication processes of typical MEMS devices;
- understand quantitatively the physics behinds MEMS operation;
- understand the type of output of typical MEMS devices.

2. Skills:
By the end of the study-unit the student will be able to:

- design basic MEMS devices;
- analyse qualitatively typical MEMS devices;
- design interface circuitry for MEMS devices as essential in the context of embedded system design;
- use MEMS design tools such as Coventorwar.
