Title: Akira Sekiya: Innovator in Chemical Vapor Deposition Technologies

Introduction

Akira Sekiya is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of chemical vapor deposition (CVD) technologies, holding a total of 6 patents. His work focuses on improving the efficiency and safety of chemical processes, particularly in the production of carbonyl fluoride and the cleaning of CVD apparatus.

Latest Patents

One of Sekiya's latest patents is a method for the production of carbonyl fluoride. This innovative process allows for the inexpensive, efficient, and safe production of COF without the use of highly toxic raw materials such as phosgene. The method involves introducing tetrafluoroethylene gas and oxygen gas into a reactor, where they are heated in a gas phase to produce carbonyl fluoride. This reactor is preferably a tubular reaction tube, and the process can utilize unpurified or purified tetrafluoroethylene gas obtained from the thermal decomposition of HCFC-22 gas. The resulting carbonyl fluoride is particularly useful as a cleaning gas for CVD devices.

Another significant patent by Sekiya involves a CVD apparatus and method for cleaning the apparatus. This cleaning method efficiently removes by-products such as SiO or SiN that adhere to the surfaces within the reaction chamber. The method minimizes the amount of discharged cleaning gas, thereby reducing environmental impacts and costs associated with the cleaning process.
