Semiconductor Manufacturing


Semiconductor manufacturing is the process of creating the integrated circuits used in electronic devices and electrical equipment.

The process involves four categories of steps including deposition, patterning, removal, and electrical modification. Each of these categories requires a range of valve and fitting solutions that meet a range of specifications.

Hy-Lok UK manufactures ultra-high purity valves and fittings that meet the specific needs of the semiconductor manufacturing industry. We manufacture tube fittings, push on hose fittings, pipe fittings, ZCR fittings, mini weld fittings, diaphragm valves, and bellow valves made of VAR 316L and VIM-VAR 316L stainless steel alloys specifically design for use in high purity applications.

We carefully select only the highest grades of raw material and have a full material and heat code traceability system. Fittings are cleaned, sanitized, and electropolished before being packed in a level 10 clean room. Our fittings can be found in the most sensitive manufacturing environments including semiconductor component, chip, and wafer manufacturing facilities.

Our products are designed to perform efficiently in a variety of harsh environments while handling a number of toxic materials. These include poisonous elements such as arsenic and phosphorus, poisonous compounds such as silane and arsine, and liquids with high reactivity such as sulfuric acid, hydrofluoric acid, and hydrogen peroxide.

We control the manufacturing process from material selection to assembly and packaging, and distribute our own products. Complete control over the supply chain allows us to provide the highest quality products and customer service.

We don't just sell the product; we are the designers, the engineers, and the fabricators. Our longstanding relationships with customers in key markets help us to continue to supply the changing needs of the markets we serve with reliable and very economically priced products.
