Thin Film Deposition
Various thin films in semiconductor devices are fundamental to chip functionality. Thin film deposition refers to the process of depositing metals, non-metals, or compound materials onto a substrate surface in the form of atoms/molecules under vacuum or gas‑phase environments, forming dense, uniform, and thickness‑controllable solid films. As a core step in semiconductor manufacturing, the quality of deposited films directly determines the electrical performance, reliability, and yield of devices.
Our company (PlutoSemi) offers a thin film deposition platform covering two major technology routes: Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). Equipped with multiple advanced deposition tools, we meet thickness requirements from nanometers to micrometers, and support various substrate materials including silicon, compound semiconductors, glass, sapphire, and flexible substrates.
I. Technology Principles
Physical Vapor Deposition (PVD): Under vacuum, source material atoms are ejected by heating or sputtering and deposited onto the substrate. Methods include electron beam evaporation, magnetron sputtering, and ion beam sputtering.
Chemical Vapor Deposition (CVD): Gaseous precursors react on the substrate surface to form solid films. Methods include LPCVD, PECVD, and atomic layer deposition (ALD).
