Content
Ubiquity of Semiconductor Devices (1L)
Semiconductor devices are hugely common in modern life,in cell-phones,computers,TVs,solar cells, lighting (light emitting diodes). How do they work inside?
Electronic devices in computers - Switches, logic, storage, DRAM, SRAM, idea of Moore's law
What is a Semiconductor (1L)
- Bonding in metals and semiconductors. Band gaps. Perodic table, Doping.
- The electron as a particle, a pin-ball model for conduction. Mobility, saturated velocity. Worked examples.
The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) (4L)
- Operating concepts of MOSFETs. Transit time. Switching speed. Gate control.
- MESFETs vs MOSFETs. Why Si not GaAs.
- Elementary discussion of Scaling and Moore's law.
Technological Challenges (5L)
- Material preparation, lithography - comparison of U.V., electron beam, X-ray.
- Oxidation of silicon
- Etching - wet and dry processes.
- Doping - diffusion, ion implantation, reduction/process limits, metallisation.
- Worked examples.
Magnetic storage technology (1L)
- Elementary principles of magnetic storage - BH loops, bits, writing, reading.
- The mechanical design of a modern hard disk drive.
- The material in a disk and read head.
Displays (3L)
- Display technologies - electricity into light.
- What are Liquid crystals.
- Active matrix liquid crystal displays.
Towards the Future (1L)
- How device dimensions and voltages reduce to give even smaller and faster transistors, towards and atomic scale.
