Study Notes
Microelectronics Overview
- Today's microelectronics field is predominantly dominated by MOSFET technologies due to their efficiency and scalability.
Development of MOSFETs
- MOSFETs were first realized in the 1960s, marking a significant advancement in semiconductor technology.
Structure of MOSFETs
- A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) consists of three primary components: the source, gate, and drain, with an insulating layer of silicon dioxide.
Interface Dynamics
- At the interface between the silicon and the insulating layer, an electric field is created, which influences charge carrier movement and device operation.
Effects of Potential Difference
- When a potential difference is applied to a MOSFET, it induces an electric field on the top plate (gate), which modulates conductivity between the source and drain.
