No. 3: Process gas and wafer cleaning agent

Process gases (a special kind of gas) and cleaning agents (for removing impurities) are often used in semiconductor manufacturing processes.

No. 2: Vacuum environments

Vacuum technology is often used in semiconductor manufacturing equipment. A vacuum is not required for all equipment. A vacuum would mainly be required for equipment that uses plasma or an electron beam. In Part 2, we introduce some NBK products that are ideal for use in these vacuum environments!

No. 1: The Semiconductor Industry and NBK

Along with the dramatic worldwide growth of semiconductors, similar development has taken place for semiconductor manufacturing equipment.
For many years, NBK has developed and sold products for semiconductor manufacturing equipment.
In Part 1, we introduce trends in the semiconductor industry, and describe some interesting efforts by NBK!
