Thin Film Sensor Technology

The thin nature of these sensors means that they often have a high relative surface area can be deformed a lot more easily than bulk materials and the small changes in a film s conductivity.

Thin film sensor technology.

Ultra thin submicron active layers with absorption coefficients much higher than those of silicon and other materials thus enabling new form factors and applications. Thin films can be deposited on and fused to many kinds of substrate including ceramic materials and high grade specialty steels. Requirements for the system the system is intended to produce sensors such as conductors capacitors resistors piezoresistive films etc. Thin film technology allows for a sensor element that is especially small and compact while retaining impressive attributes in terms of precision and lasting stability.

A familiar example is the household mirror which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. Thin films have found an array of uses in sensor technology because they are more sensitive to changes in a local environment than many bulk materials. Danfoss media relations. Imec develops disruptive technologies for image sensors based on thin film photodetectors.

Thin film layers of different materials are built up using masking techniques to create electronic devices on the surface of the base material. The controlled synthesis of materials as thin films a process referred to as deposition is a fundamental step in many applications. A thin film is a layer of material ranging from fractions of a nanometer to several micrometers in thickness. Thin film deposition is the process of generating a very thin coating of material onto another thicker substrate material.
