Applications in the semiconductor industry

Acid preparation and chemicals

In the semiconductor and microelectronics manufacturing process, industrial etching, uses etching chemical baths to create objects of desired shapes. The etching chemical baths need precise temperature and concentration control, where plate and frame heat exchangers are critical in the acid preparation and controlling the temperature of the etching chemical baths. Tranter’s plate and frame heat exchangers can be manufactured with plates in various high alloys or nickel alloys, capable of handling corrosive chemicals and acids.

Water treatment – Ultrapure water (UPW)

Water treatment of ultrapure water (UPW) and process cooling medium is vital in the semiconductor industry to ensure the water’s purity and temperature for the different manufacturing processes. Plate heat exchangers are optimal for precise temperature control of the process cooling medium, helping pants to reduce their total water consumption. Ultrapure water (UPW), mainly used for the manufacturing of computer microchips, need precise temperature control and cleanliness. Tranter’s welded plate heat exchangers in titanium ensure cleanliness and precise temperature control in this process.

Wafer preparation

Wafers are thin slice of silicone ingots used as semiconductor material used as the substrate in various microelectronics for fabrication of integrated circuits. Following the several microfabrication processes like etching, ion implantation, materials deposition and photolithographic patterning, the microcircuits are diced into wafers using wire saws. The silicone ingots are cut using high temperature wire saws that need coolant/cutting slurry which need to be cooled using plate heat exchangers. Tranter’s gasketed plate heat exchangers offers a compact, highly efficient and reliable design for this cooling application.
