that are required in today's semiconductor manufacturing. Improving the purity of the
gas involves increasing the effectiveness of purifiers and filters, as well as using ultra-
clean gas flow systems. Conventional wisdom indicates that in order to make a gas
supply ultra clean, the areas that come in contact with the gas must be extremely well
polishes, and the entire system should be metal. In the mass flow controller field,
where the structure of gas supply systems is necessarily extremely complex, the above
were considered difficult conditions to meet. Yet HORIBA STEC succeeded in
developing a method for mass producing metal diaphragm valves, and in 1984, the
company released its SEC 4000 series of all-metal mass flow controllers, which came
to be known as the ultra clean mass flow controllers.
