Semiconductors: The Foundation of IC Technology
Integrated circuits (ICs) are the building blocks of modern electronics. They are made from semiconductors, which are materials that can conduct electricity under certain conditions. The most common semiconductor material is silicon.
Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs): The Workhorse of Digital Circuits
MOSFETs are the most common type of transistor used in ICs. They are made by sandwiching a thin layer of metal between two layers of semiconductor material. The metal layer is called the gate, and the semiconductor layers are called the source and drain. When a voltage is applied to the gate, it creates an electric field that controls the flow of current between the source and drain.
Complementary Metal-Oxide-Semiconductor (CMOS) Technology: The Standard for Digital Logic
CMOS technology is a type of IC technology that uses MOSFETs to create digital circuits. CMOS circuits are very efficient and can be used to create complex circuits with low power consumption. CMOS technology is the standard for digital logic, and it is used in the vast majority of digital circuits.
Advanced CMOS Technologies: Pushing the Limits of Performance
Advanced CMOS technologies are pushing the limits of performance, and they are being used in a variety of applications, including artificial intelligence and machine learning. These technologies include:
-
FinFETs: FinFETs are a type of MOSFET that has a thin, fin-shaped channel. FinFETs are faster and more energy-efficient than traditional MOSFETs.
-
Gate-all-around (GAA) MOSFETs: GAA MOSFETs are a type of MOSFET that has a gate that surrounds the channel on all sides. GAA MOSFETs are even faster and more energy-efficient than FinFETs.
Silicon Carbide (SiC) and Gallium Nitride (GaN): The Future of Power Electronics
SiC and GaN are emerging technologies, and they are expected to be used in a variety of power electronics applications. These technologies have a number of advantages over traditional silicon-based power electronics, including:
-
