GB/T 44842-2024 Micro-electromechanical systems(MEMS) technology—Bend testing methods of thin film materials
Basic Information
Scope
This document describes the bending test method for thin film materials with a length and width of less than 1 mm and a thickness of 0.1 μm to 10 μm. Thin films are used as the main structural materials in micro-electromechanical systems (MEMS) and micromachines.
As the main structural materials in devices such as MEMS and micromachines, thin films have unique characteristics, such as being a few micrometers in size, being prepared using deposition and photolithography processes, and/or having non-machined test structures. This document describes the bending test method for micro-scale smooth cantilever test structures and the shape of the test structures, in order to ensure test accuracy that corresponds to the unique characteristics of the thin film materials.
