Toseye Hesgarsazan Asia (Sensiran) is an industrial and research company was found in 2001 in Technology Pardis Park in Boomhen, Tehran, Iran. This is a knowledge-based company which relies strongly on the development of laboratory facilities as well as conventional sensors for gas and flow detection. In 2008, we introduced our first direct-current plasma enhanced chemical vapor deposition (PECVD) unit called as PE-800 for the growth of carbon nanotubes and nanostructures. This unit was upgraded to PE-802 and PE-803 where more deposition reactors were integrated to improve the performance of the unit. Later on the first version of low-pressure CVD (LPCVD) called as LP-80 was introduced, which allows the growth of polysilicon, silicon-nitrides and silicon nanowires. The unit has been adjusted to hold a high safety standard both in terms of the gas handling unit as well as the main reactor.
