Reaction Mechanisms of Chemical Vapor Deposition

Chemical vapor deposition (CVD) is a process used to grow a film of solid material by transporting a chemical precursor in its vapor phase and decomposing it through heat. Typically, a material in its solid form is vaporized and diluted … Continue reading […]

Principles of Light Sources for Lithography

It has been proven that the design lenses which images near the diffraction are limited only over narrow bandwidths in wavelength. This is a consequence of the phenomenon of dispersion where index of refraction changes with the wavelength of the … Continue reading […]

Light Sources Used in Photolithography

Lithography comes from the Greek words lithos, which means ‘stone’, and graphein, which means ‘to write’.  It is the process used to print by transferring a mirror image of the pattern from the flat surface. It was developed in 1976 … Continue reading […]

Photolithography, how does it work?

Photolithography is one of the main parts of the microprocessor manufacturing steps. There are currently three types of photolithography processes: contact alignment photolithography, proximity alignment photolithography, projection or stepper lithography. Contact alignment lithography is the simplest and involves a light … Continue reading […]
