To evaluate the etching effect, many critical indicators need to test and analyze after the etching process is completed, such as etching uniformity, etching bias, etching profile, etching residue, etc. Alfa chemistry has the ability to evaluate these indicators to ensure the etching effect.
Alfa Chemistry has advanced analytical instrument, high-skilled testing team and rich testing experience. We offer advanced research methods and comprehensive analysis expertise to help you evaluate and improve the etching process.
Alfa Chemistry has the ability to judge the etching effect by evaluating different etching indicators. The etching indicators we can evaluate include but are not limited to the following.
Alfa Chemistry has professional analytical instruments, including but not limited to the following.
Scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. SEM can detect the topography, thickness and CD of etching film layers.
Focused ion beam (FIB) is a technique used particularly in the semiconductor industry, materials science and increasingly in the biological field for site-specific analysis, deposition, and ablation of materials. FIB can test etching profile in etching process.
Energy-dispersive X-ray spectroscopy (EDX) is an technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of some source of X-ray excitation and a sample. EDX analyzes etching residue by detecting chemical elements.
