CVD (Chemical Vapor Deposition) is used to deposit materials in various forms, including monocrystalline, polycrystalline, amorphous, and epitaxial. By subtypes, there are mainly LPCVD (low pressure), PECVD (plasma enhanced), and ALD. PVD deposition techniques include sputtering and eBeam and thermal evaporation.
The CVD process involves mixing the source material with one or more volatile precursors using a plasma to chemically interact and breakdown the source material. The processes use heat with higher pressures leading to a more reproducible film where the film thicknesses could be managed by time/power. These films are more stoichiometric, they are denser and are capable of growing higher quality insulator films. The PVD processing uses a solid precursor metal that is gasified through some electrical energy. The gasified atoms are then transferred to the substrate. These processes manages thicknesses using a quartz crystal rate monitor to control rate and thickness of the film.
ALD films are very conformal approaching 2000:1 aspect ratios, thus providing excellent step coverage over features. The process is repeatable and can grow thinner layers under 10nm thickness predictably. Films include Alumina oxide (AL2O3), Hafnium oxide (HfO2) and Titanium oxide (TiO2). Its use in the semiconductor industry has advanced ALD rapidly in recent years to develop thin, high-K gate dielectric layers.
The PECVD process offers good step coverage over features. Films include Silicon Dioxide (SiO2), Silicon Nitride (Si3N4) and lower stress Oxynitride (SiON) films. The PECVD films offer more flexibility than ALD with higher deposition rates leading to higher throughputs.
This report discusses the technology trends, products, applications, and suppliers of deposition materials and equipment. It also gives insights to suppliers for future user needs and should assist them in long range planning, new product development and product improvement. Market shares and a market forecast for each sector of thin film deposition tools is presented.
