About: Sensor - DBpedia

Sensors are usually designed to have a small effect on what is measured; making the sensor smaller often improves this and may introduce other advantages. Technological progress allows more and more sensors to be manufactured on a microscopic scale as microsensors using MEMS technology. In most cases, a microsensor reaches a significantly faster measurement time and higher sensitivity …

Chemical Mechanical Polishing - an overview | ScienceDirect …

In optical micro electromechanical systems (MEMS), the thin films with a highly smooth surface finish are of great importance because it enhances the device performance. The implementation of CMP in planarizing the thin films in optical (MEMS) systems imparts a mirror like surface finish on the layers. It is also used in manufacturing flat monitor screens, photo diodes, optical fiber, telecommunication laser, …

(PDF) Photocurrent Chemical Image Response of MOS Gas Sensor …

The sensor was photo excited locally by laser pulse source throughout a glass window and the photocurrents were measured before and after gas injection. The spot of laser light was scanned throughout the surface of the sensor (metals and SiO 2 regions) building photocurrent images. It is worth to mention that the scanned area was limited to region where the Au and Pd electrodes showed a …
