Which of the following is not a common use for steam?

Steam is commonly used in various industrial processes due to its ability to transfer heat efficiently and its versatility as a medium for energy transfer. In the context of computer chip manufacturing, however, steam is not typically utilized as a primary method in the fabrication processes. The production of microchips involves processes such as photolithography, etching, and deposition, which primarily rely on chemicals and gases rather than steam.

In contrast, steam has established roles in the other listed applications. In cooling systems, it works in steam cycles to transfer heat. Steel manufacturing uses steam or steam-related processes for heating and processing materials. For removing skin from potatoes, steam is an effective method to loosen the skin, making it easier to peel. Each of these applications leverages the unique properties of steam, whereas computer chip manufacturing relies on a different set of processes that do not include steam as a significant element.
