High density plasma etching
Web摘要: Etch anisotropy and microscopic uniformity have been investigated in low-pressure, high-density plasma etching environments. Polycrystalline Si films masked with a photoresist pattern of lines and spaces were etched in electron cyclotron resonance (ECR) Cl_2 and Cl_2/O_2 plasmas with additional rf biasing.

WebInductively coupled plasma etchers produce higher plasma density and are hence called HDP, High Density Plasma, systems. These have two sources of plasma power. The first, a non-capacitive coupled source, such as inductively coupled (ICP) or ECR coupled, where power is transferred or coupled to the plasma with minimal voltage difference between …

Oxygen–plasma treatment was performed on in situ SiN, before SiO2 gate insulator was deposited by plasma-enhanced chemical vapor deposition (PECVD). DC I-V … Web31 de jul. de 2015 · Inductively coupled plasma reactive ion etching (ICPRIE) of Ru thin films patterned with TiN hard masks was investigated using a CH 3 OH/Ar gas mixture. As the CH 3 OH concentration in CH 3 OH/Ar increased, the etch rates of Ru thin films and TiN hard masks decreased. However, the etch selectivity of Ru films on TiN hard masks …
Web1 de mai. de 1997 · Inductively coupled plasma (ICP) etching of GaAs, GaP, and InP is reported as a function of plasma chemistry, chamber pressure, rf power, and source power. Etches were characterized in terms of rate and anisotropy using scanning electron microscopy, and root-mean-square surface roughness using atomic force microscopy. … WebA notching effect (or footing effect) is seen when high-density plasma etching reaches an insulator surface, e. g. SOI buried oxide or oxide on the backside of the wafer in through-wafer etching (Fig. 2). Charging of the interface leads to ion deflection and ion-enhanced sideways etching at the insulator–silicon interface.
Web25 de set. de 2024 · High density plasmas are attractive to treat (clean, dope, and pattern) 2D materials, because they are a mature industrial technology adapted to large area wafer. However, in these plasmas, the substrate is bombarded by a high flux of both thermal radicals and reactive ions with typical energy above 10 eV, which can easily damage … shsu absence formWebHigh-density plasma systems secondary excitation source that is not capacitively coupled; instead inductively coupled plasma (ICP); growing popularity Induction coils Plasma density no longer depends on pressure.
