surface condition
Surface State
Surface state, in physics, refers to the surface electrons of a material which have been atomically modified during preparation of the surface to create a region of electric conductivity. The states on the surface are generally different from those of the bulk due to the unique elec......
surface defect cleaning
Surface Defects Cleaning
Surface defects are those small semiconductors that appear on the surface of a material due to different kinds of processes. They can have a variety of shapes including circles, dots, and spots. These types of defects are usually caused by crystalline growth, crack closur......
Application of Ultra High Vacuum Technology in Surface Treatment System
Introduction
The development of vacuum technology has been hailed as a revolution in the surfaces of materials processing and this is because of its ability to produce uniform and predictable surfaces. As research in the area of vacuum system handling and processing increases, so does the range o......
Ionic surface treatment
Introduction
Surface treatments using ion implantation dates back to about five decades and has been extensively used for various applications in the semiconductor industry. It is a material modification process that changes the physical and chemical properties of the surface of an item without a......
ion nitriding
Ion Nitride Technology
Ion nitride technology is a type of semiconductor material processing which involves the deposition of binary compounds such as silicon nitride and phosphorous nitride onto a wafer or substrate. The technology is employed in the production of microelectronic devices, such a......
Common Defects of Ion Nitriding
The presence of nitrogen ions in ion-exchange membranes is essential in order to improve the proton and ionic conductivity of the membrane material. However, the process of introducing nitrogen ions into the membrane material can produce dislocations or other defects that can negatively impact mem......
