Process Ways to Improve The Mechanical Strength of Film Layer
The mechanical properties of the membrane layer are affected by the adhesion, stress, aggregation density, etc. From the relationship between the membrane layer material and process factors, it can be seen that if we want to improve the mechanical strength of the membrane layer, we should focus o...Read more -
Chemical Vapor Deposition
Epitaxial growth, often also referred to as epitaxy, is one of the most important processes in the fabrication of semiconductor materials and devices. The so-called epitaxial growth is in certain conditions in the single crystal substrate on the growth of a layer of single product film process, t...Read more -
Types of CVD Technology
Broadly speaking, CVD can be roughly divided into two type: one is in the single product on the substrate vapor deposition of single-crystal epitaxial layer, which is narrowly CVD; the other is the deposition of thin films on the substrate, including multi-product and amorphous films. According t...Read more -
Transmission and Reflectance Spectra and Color of Optical Thin Films Chapter 2
From this we are about to clarify: (1) thin-film devices, transmittance, reflectance spectra and the color of the corresponding relationship between, that is, a spectrum of a color; on the contrary, this relationship is “not unique”, manifested as a color multi-spectrum. Therefore, the film’...Read more -
Transmission and Reflectance Spectra and Color of Optical Thin Films Chapter 1
Transmission and reflectance spectra and colors of optical thin films are two characteristics of thin film devices that exist at the same time. 1. Transmission and reflectance spectrum is the relationship between reflectance and transmittance of optical thin film devices with wavelength. It is c...Read more -

Plasma Enhanced Chemical Vapor Deposition Chapter 2
Most chemical elements can be vaporized by combining them with chemical groups, e.g. Si reacts with H to form SiH4, and Al combines with CH3 to form Al(CH3). In the thermal CVD process, the above gases absorb a certain amount of thermal energy as they pass through the heated substrate and form re...Read more -
Plasma Enhanced Chemical Vapor Deposition Chapter 1
Chemical Vapor Deposition (CVD). As the name implies, it is a technique that utilizes gaseous precursor reactants to generate solid films by means of atomic and intermolecular chemical reactions. Unlike PVD, the CVD process is mostly carried out in a higher pressure (lower vacuum) environment, wi...Read more -
