Abstract
In a thin film circuit, high values of resistance/surface area can be attained by forming the resistive material as a mesh rather than a solid block. The advantages of this are that it gives a high resistance value in a small area and allows laser trimming, both without adversely affecting resistor characteristics such as stability.
