The aim of this module is to introduce the student to the theory, and design
of MOS Field-Effect Transistors (MOSFETs), based on both single crystal and
thin-film materials. This will be followed by application examples, including chemical/biological sensors in sensor technologies,ferroelectric and magnetic random access memories (FRAM and MRAM) in non-volatile memory technologies, and active matrix liquid crystal displays and micromechanical displays in display technologies. Emphasis will be placed on both device physics and application technology.
- MOS Devices Introduction (3L)
Properties of MOS Capacitors,
Capacitance - voltage characteristics; MOSFET structures and operation.
- MOS Devices & Thin Film Transistors (5L)
Short channel and hot
electron effects; Applications and future trends in miniaturising single crystal
devices; Amorphous and polycrystalline silicon and other thin-film transistors. Organic thin-film transistors, Ion-sensitive thin, film trasistors and biosensors.
- Non-Volatile Memory Devices and Displays (5L)
Ferroelectrics and ferroelectric random access memories; Giant magneto-resistance (GMR) and magnetic random access memories. Directly driven liquid crystal displays; Active matrix liquid crystal displays and projectors; Micromechanical projectors; Other types of displays and emerging technologies.
On completion of the module the student should:
- Understand MOSFET theory and standard approximations;
- Be able to correlate material properties and conduction mechanisms with the MOSFET electrical
characteristics, for single crystal, amorphous and polycrystalline devices;
- Understand the basic properties of ferroelectrics and its application for memory devices.
- Understand the concept of giant magneto-resistance and its applications including non-volatile memory devices
- Understand the operation of liquid crystal displays;
- Understand the construction and operation of micromechanical displays, and other emerging display technologies.
