Study Notes

Doping in Semiconductors

Doping is the process of intentionally adding impurities (dopants) to a semiconductor to control the carrier concentrations.
The two kinds of electrical charge carriers in semiconductors are electrons (negatively charged) and holes (positively charged).

Silicon Crystal Structure

The periodic structure of a crystalline solid, like silicon, is determined by X-ray diffraction.
Chapter 1 of the textbook provides the basic concepts for understanding semiconductors.
Dopants are used to control carrier concentrations in semiconductors.
The lattice constant of the silicon crystal is 5.43 Å.
A silicon atom has four valence electrons.
The structure shown in Fig. 1 is a diamond lattice, which is also the unit cell of the diamond crystal.

Silicon Crystal and Carrier Movement

When an electron breaks loose and becomes free in the silicon crystal, it creates a hole, which acts as a positive charge carrier.
Each silicon atom in the silicon crystal is surrounded by four nearest neighbors.

Microelectronics and Microfabrication

Microfabrication techniques are primarily used to create miniature electronic devices and circuits in microelectronics.
The main advantage of MEMS-based sensor devices is their small size and low power consumption.
Sensors in microelectronic systems detect and measure physical quantities such as temperature, pressure, and acceleration.
MEMS technology combines microelectronics with micromachining to create tiny mechanical devices.

Semiconductor Materials and Microelectronics Technology

Semiconductor materials are essential components in microelectronics technology, forming the basis of transistors, diodes, and integrated circuits.
The primary function of integrated circuits (ICs) in microelectronics technology is to perform complex electronic functions within a small space.
Silicon and gallium arsenide are widely used materials in the fabrication of integrated circuits and microelectromechanical systems (MEMS).

Microfabrication and MEMS in Microelectronics

The main purpose of microfabrication techniques is to create small and complex features on a chip or wafer.
MEMS plays a crucial role in microelectronics technology by enabling the fabrication of miniaturized sensors, actuators, and other devices.
Complementary metal–oxide–semiconductor (CMOS) technology is commonly used in microelectronics for fabrication of logic circuits and memory devices.
