What is DIFFUSION


In electronic components, 'diffusion' is one of the semiconductor manufacturing processes, which means the process of injecting ions or atoms into semiconductor materials to form desired materials. Diffusion is used to control the distribution of doping materials within semiconductor devices or to form semiconductor regions with desired characteristics.

Diffusion consists of the following steps:

Purification: Refining semiconductor raw materials and preparing components in a clean state. This process ensures an accurate diffusion process by removing impurities and keeping the semiconductor substrate clean.

Masking: During the diffusion process, a masking material is used to protect the substrate to define the desired semiconductor region. Masking restricts the area so that diffusion only occurs where desired.

Diffusion: Inject the desired material into the substrate using diffusion equipment. Ions or atoms penetrate the surface of the semiconductor substrate and diffuse into the substrate to control the concentration of the substance. Diffusion time and temperature are important parameters that determine the diffusion rate and concentration of a substance.

Reverse Diffusion and Purification: Once diffusion is complete, unwanted material is removed using reverse diffusion or diffusion equipment. This step is performed to purify the semiconductor substrate.

Diffusion is one of the important steps in the semiconductor manufacturing process, and it affects the electrical characteristics and operation of semiconductor devices. In particular, diffusion is used for important tasks such as controlling the doping level of semiconductor devices, forming pn junctions, and creating multilayer structures.
