Electrical Characteristics of Solids
When it comes to electrical characteristics, solid matter falls into one of three categories: it is either a conductor, an insulator, or a semiconductor, depending on whether or how ...
Technical Notes
Electrical Conduction in Semiconductors
The electrical property that makes semiconducting materials so valuable in electronics applications arises from the fact that their electrical conductivity can be continuously vari ...
Technical Notes
Diode Physics
The characteristic response of a solid state diode to an external electrical potential or to an energy source such as light forms the basis for devices such as bipolar junction transistors, ...
Technical Notes
Bipolar Junction Transistor Physics
BJT operation involves both electrons and holes. It can be configured as either a PNP transistor or an NPN transistor which can be constructed as either a three-layer sandwich or as ...
Technical Notes
FinFET Physics
It can be seen that all of the familiar components of a MOS device are present in the FinFET (drain, source, gate, gate dielectric) and that the device more effectively separates the ...
Technical Notes
Flash Transistor Physics
Flash transistors are used in memory devices. Their design is similar to that of MOSFETs with the main design difference being that they employ two gates rather than one.
Technical Notes
Compound Semiconductor Epitaxial Thin Films
Compound semiconductors are materials such as GaAs, AlGaAs, GaN, CdSe, InP, InSb, etc. These materials combine the elements from equidistant columns on either side of Column IVA of ...
Technical Notes
Dielectric Thin Films
Thermal SiO2 films for device components can be formed in a variety of ways; the selection of method is dependent on such factors as substrate composition/topography and the thermal ...
Technical Notes
Creating a Vacuum
An in-depth understanding of the creation of vacuum requires consideration for physical characteristics such as gas viscosity, flow type, the thermal conductivity of the gas, and gas ...
Technical Notes
Capacitance Manometer Physics
The capacitance gauge translates a pressure-modulated movement in a thin diaphragm into an electrical signal proportional to the pressure.
Technical Notes
Chemical Vapor Deposition Physics
Chemical vapor deposition processes can be defined as: any process in which a thin solid film is formed on a substrate by the surface-mediated reaction of adsorbed precursors from the ...
Technical Notes
Cleanroom Ultra-clean Air Delivery
Semiconductor fab environments require ultra-clean conditions to ensure low numbers of product defects due to particulate contamination. A critical aspect in creating an ultra-clean ...
Technical Notes
Electrical Conduction in Solids
The physical mechanism of electrical conduction in solids is best understood using a model that physicists refer to as "band theory", which is based on the idea that the state of an ...
Technical Notes
Silicon Based Epitaxial Thin Films
Epitaxy is defined as the "regularly oriented growth of one crystalline substance on another". Both homoepitaxy and heteroepitaxy processes are used in semiconductor device fabrica ...
Technical Notes
Vacuum Pressure Basics
In simple terms, vacuum may be defined as: A space or container from which the air has been completely or partially removed.
Technical Notes
Vacuum Measurement Principles
The first true pressure measurement was made by Evangelista Torricelli in the 17th Century, when he invented the mercury barometer and measured atmospheric pressure.
Technical Notes
Spinning Rotor Vacuum Gauge Physics
Spinning rotor gauges (SRGs) also known as molecular drag or viscosity gauges, measure the number density of the surrounding gas.
Technical Notes
Ultrapure Water for Semiconductor Manufacturing
This technical note provides a basic familiarity with the design elements and functionalities for UPW systems. We will discuss the main UPW parameters, the treatment sequence for UPW ...
Technical Notes
Vacuum Pressure Control for Semiconductor Fabrication
Stable and precise control of a processing system's vacuum pressure is critical for high-yield semiconductor device fabrication. Processes such as SAPCVD, LPCVD and etch exhibit optimal ...
Technical Notes
P-N Junction Physics
When p-type semiconductor and n-type semiconductor materials are placed in physical contact, the area around the contact (known as the junction) behaves differently than either of the ...
