Producing the semiconductor chips found in electronics from mobile phones to space-faring satellites today is the result of building circuits at a nanoscopic scale, where chemical reactions deposit or decompose into desirable material films that make up switching transistors and planar conductivity circuits in silicon wafers. A leading semiconductor equipment manufacturer recently engaged Whitman Controls to provide instrumentation for a new generation of their production machinery, specifically in the form of evacuation control for the vacuum chambers on their atomic layer deposition equipment.
Semiconductor manufacturing transforms raw silicon, polymers, and metallic materials into electrical transistor switching wafers using production equipment and processes that operate in spaces measured in nanometers. At this scale, precision, accuracy, and fidelity are of the utmost importance. We provide a few examples of semiconductor manufacturing applications, each presenting unique demands onto their control system’s sensors.
