Course detail

Microelectronic Devices and Structures

FEKT-MPA-MPRAcad. year: 2023/2024

The subject expands and deepens knowledge about semiconductor components from the subject of the bachelor's degree. The aim is to acquaint students with selected parameters and properties of selected types of electronic components in relation to the basic physical principles of components. Students will be introduced to the properties of modern semiconductor components (JFET, MOSFET and IGBT) based on Si, SiC and GaN, including their use in electrical engineering circuits. The goal of practical jobs is to deepen students' theoretical knowledge by experimentally verifying the properties of selected modern semiconductor components using automated measurement tools (LabVIEW) and simulations.

Entry knowledge

Basic knowledge of physics, mathematics and electrical circuits is required.

Work in the laboratory is subject to a valid qualification of "instructed person", which students must obtain before starting classes. Information on this qualification can be found in the Dean's Directive Acquainting Students with Safety Regulations.

Rules for evaluation and completion of the course

Point evaluation (max. 100 points): max. 30 points for work during the semester; max. 70 points per exam.

The final exam consists of two parts (written and oral) and is evaluated for a total of 70 points.

Aims

The goal of the master's extension course is to expand and deepen knowledge about semiconductor components from the bachelor's degree course. The aim is to emphasize the relationships between the physical principle of the component and the actual realization of the component. The subject should emphasize the connections and relationships between the properties of the starting semiconductor material and the properties of the semiconductor component. In the exercises, students will learn to interpret basic quantities in semiconductor materials and structures. The goal of practical jobs is to deepen knowledge by experimental verification of selected semiconductor components, especially by measuring their characteristics and parameters.
