GB/T 42896-2023 in English

GB/T 42896—2023 Standard Overview

This standard mainly specifies the test method for the impact resistance of silicon-based MEMS nanoscale structures under impact loads in microelectromechanical systems (MEMS) technology. It is applicable to nanoscale structures manufactured using microelectronics technology, with particular attention paid to the assessment of their impact resistance under a single impact load.

Core content interpretation

1. Background and significance of standard formulation

With the rapid development of MEMS technology, nanoscale structures are increasingly used in microelectronics, optoelectronics, biomedicine and other fields. However, these microstructures face complex mechanical environments in actual use, especially under the action of impact loads, which may cause failure. The formulation of this standard fills the gap in the assessment method of the impact resistance of silicon-based MEMS nanoscale structures, and provides an important basis for the quality control and reliability assessment of MEMS devices.

2. Explanation of Key Terms

• In situ on-chip impact tester: A test structure and a test device integrated on the same wafer, used to evaluate the impact resistance of micro-nano structures.
• Testing structure: A micro-nano structure specially designed to measure the properties of materials or microstructures, such as a cantilever beam or a fixed beam.
