Basic Information
Scope
The main technical content: The high-precision characterization of the concentration and distribution of trace impurity elements in semiconductor materials is an important parameter affecting the performance of products at different stages of the industrial chain (such as substrates, epitaxial layers, chips, and devices). Secondary ion mass spectrometers are the most commonly used and accurate equipment for detecting the concentration and distribution of trace impurity elements in materials. At present, China's standards for high-precision detection of trace impurity concentrations and distributions in third-generation semiconductor materials by secondary ion mass spectrometry belong to a blank field. Therefore, the formulation of this standard will have a significant positive impact on the evaluation of the characteristic parameters of third-generation semiconductor materials and their industrial applications.
