摘要:
A diagnostic plasma measurement device is provided having sensors and features disposed using pattern transfer fabrication techniques. A measurement device comprises a primary substrate with sensors for measuring plasma or surface properties disposed by a stepped pattern transfer technique, such as step-and-repeat photolithography, about the surface of the probe. Sensor fields include sensors that measure physical and electrical properties of a plasma, as well as sensors that measure properties of the wafer surface. Fields or components for processing electronics, electrical interconnections, memory, photovoltaic power, and wireless communication are also provided. By utilizing pattern transfer fabrication techniques, the invention generally provides for reduced risks of contamination of a plasma processing environment and increased manufacturability and reliability of the completed sensor device.
