Aim:
The aim of the course is to present the fundamental principle of semiconductor devices and how models of devices can be created from this understanding. How the semiconductor devices are fabricated? Basic unit processes will be presented. The students get the basic knowledge that is necessary to understand, work and produce integrated circuits and optoelectronics. After this course the student should
- Describe manufacturing steps, lithography, oxidation, metallization, and etching.
- Integrate the manufacturing steps for manufacturing of bipolar transistors, MOSFET, CMOS and MEMS.
- Explain the terms, band gap, energy level, mobility, effective mass, charge generation and recombination, doping, drift, diffusion, equilibrium and steady state.
- �?� Apply relations between band gap, energy level, mobility, effective mass, charge generation and recombination, doping, drift, diffusion, conductivity, current density, temperature and illumination in semiconductors.
- Calculate and determine the material parameters (band gap, doping, level, carrier lifetime, diffusion length) from electrical characteristics of semiconductor devices.
- Design pn-junctions, Schottky diodes, bipolar transistor, MOSFET, and pn-solar cells having given characteristics.
- Design pn-junctions, Schottky diodes, bipolar transistor, and MOSFET.
