Brand: Synthesis
Synthesis flame, also known as a non-luminous flame or a chemical reaction zone, is a specialized flame used in chemical processes like chemical vapor deposition (CVD) and plasma-enhanced chemical vapor deposition (PECVD) in semiconductor manufacturing, thin-film coatings, and nanotechnology. This type of flame differs from the traditional visible flame used for combustion in that it is not visible to the naked eye, but instead appears as a translucent blue or green glow. This unique trait is caused by the absence of soot formation, unlike a traditional flame, which is caused by the presence of unburnt hydrocarbons. Instead of a conventional flame, a synthesis flame is generated by a chemical reaction between precursor gases and a plasma discharge. The flame's temperature, pressure, and chemical composition are controlled through various parameters, such as gas flow rate, plasma power, and substrate position, to optimize the deposition process. Overall, the synthesis flame is a critical component in many industrial and technological applications, enabling precise material deposition processes at high temperatures.
