Iranian Firm Develops Thin-Film Thickness Gauge

“This device, which has also been patented, measures the thickness of thin films to an accuracy of 2 nanometers by shining light beams at different angles on the sample and analyzing optical data,” said Ali Salehpour, the managing director of the knowledge-based company.
“The main innovation of this product is in the idea of data analysis, not physical complexity. By comparing practical and theoretical data, a graph is obtained that shows the thickness of the sample at different points,” he added.
Noting that the device is specially designed for industries that use deposition systems (such as the production of semiconductor components or anti-scratch coatings), Salehpour said, adding, “The company's second flagship product is an optical surface profiler that uses interferometry technology. This device is capable of mapping surface topographies with an accuracy of 5 nanometers and, unlike atomic force microscopes (AFM), allows for the observation of areas as small as one square millimeter.”
In a relevant development in July, specialists of an Iranian knowledge-based company had also succeeded in reverse engineering and indigenization of the sensors for level gauges, one of the key equipment needed in the oil and gas industry.
“In a company active in the field of oil and gas, we reverse engineered one of the key equipment of the oil industry. The complex equations that were used in the design of this equipment required a combination of several different parameters to achieve a final result. Relying on the knowledge and expertise of our team, we managed to discover and solve these equations,” said Monireh Parsa, the managing director of the knowledge-based company.
“This equipment is a level gauge sensor that works by immersion and using a trig tube. As one of the methods of measuring the height of the fluid, unlike the buoyancy model, the submersion method is very complicated, but its low sensitivity to density and lack of influence from fluid vapors has made it one of the most widely-used methods in the oil, gas and petrochemical industries. The immersion sensor made by Shahrah Mechatronic Pars company is suitable for the market and application,” she added.
“This product has been manufactured for the first time in Iran and at present, it is used in refineries, petrochemicals and other industries,” Parsa noted.
