Thin Film Sensor Technology

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 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. 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. 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 film deposition surface layer. 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. Thin film layers of different materials are built up using masking techniques to create electronic devices on the surface of the base material.

Deposited on 200 mm wafers. The controlled synthesis of materials as thin films a process referred to as deposition is a fundamental step in many applications. Thin films can be deposited on and fused to many kinds of substrate including ceramic materials and high grade specialty steels. 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.
