What does PECVD?
PECVD is a well established technique for deposition of a wide variety of films. Many types of device require PECVD to create high quality passivation or high density masks.
Why use LPCVD?
Comparing LPCVD to other CVD processes the main advantages of LPCVD are the excellent uniformity of thickness and purity, simple handling, high reliability, homogeneity of deposited layers and high reproducibility.
How plasma is formed in Pecvd?
PECVD is a widely used technique to obtain device quality thin films at low substrate temperatures [36]. In PECVD, source gases are decomposed in plasma by the collisions between energetic electrons and gas molecules.
What is ALD process?
Atomic layer deposition (ALD) is a vapor phase technique used to deposit thin films onto a substrate. The process of ALD involves the surface of a substrate being exposed to alternating precursors, which do not overlap but instead are introduced sequentially.
What is step coverage in CVD?
Step coverage is defined as the ratio of film thickness on the bottom of the stripe to that on the top surface. Source publication. Good Conformability of Indium-Tin Oxide Thin Films Prepared by Spray Chemical Vapor Deposition.
Is PECVD conformal?
Conformality or Step Coverage ALD, TEOS, HTO, and thermal oxide are very conformal. LTO, PECVD, sputtering, and evaporation are much less conformal.
What is PECVD?
What is PECVD? Plasma Enhanced Chemical Vapor Deposition Goal: Deposition of thin films using plasma assistance to avoid undesirable temperatures 4 Technology for PECVD Applications Passivation/Encapsulation/Insulation Capacitor dielectric Masking General Case of Chemical Vapor Deposition
Why choose Plasma-Therm PECVD?
Plasma-Therm has been a leader in PECVD technology for more than 30 years. We offer numerous innovations in our PECVD systems that produce high-quality films.
