Reactive ion etching and plasma etching of tungsten

Microelectronic Engineering, 1993
Abstract Tungsten etching has been studied in audio frequent plasmas with NF3-O2 and SF6-O2 mixtures. The influence of etch mode, gas flows, pressure and power has been investigated. It is possible to etch tungsten chemically but large concentrations of free fluorine are needed. These are supplied more easily by NF3 than by SF6.

Reactive ion etching of LiNbO3

Applied Physics Letters, 1981
We describe the reactive ion etching of LiNbO3 in gas mixtures containing CCl2F2, CF4, O2, and Ar. The effects of gas composition and pressure, in the range 1–10-μm total pressure are discussed. Because it is possible to replicate fine features (∼2000 Å) with control of etch profiles, we expect the process to be used for three-dimensional patterning of

Reactive ion etching of silicon

Journal of Vacuum Science and Technology, 1979
Reactive ion etching of silicon substrates in a plasma containing chlorinated species does not result in undercut of a permanent mask. When the silicon is very highly doped it behaves as a different material and undercut has been observed. This phenomenon will be discussed.

Reactive ion etching of diamond

Applied Physics Letters, 1989
A reliable means of removing surface layers of diamond is of significant importance for microelectronics as well as for other applications such as polishing of the diamond surface. Preliminary studies using reactive ion etching with O2 and H2 showed etching rates of the order of 560 Å/min for thin carbon films and 350 Å/min for natural type II-A ...

Reactive ion etching of niobium

Journal of Vacuum Science and Technology, 1981
The reactive gases CBrF3 and CF4 have both been found to be effective in the reactive ion etching of niobium. At relatively high pressures, 100 mTorr, rapid etching with a small degree of undercutting occurs at moderate rf power levels. At lower pressures, higher rf power levels, ≳1 W/ cm2, are required but vertical edge profiles result.

Reactive Ion-Beam Etching

1984
Publisher Summary This chapter discusses reactive ion-beam etching (RIBE), which is the technique of removing material from a surface by impinging on it a beam of chemically reactive ions. In fact, RIBE has played a dual role in the evolution of dry-etching techniques for electronic device and integrated circuit applications. For as well as providing

Reactive-Ion Etching

Physics Today, 1986
Our ability to develop and build ever smaller microelectronic devices depends strongly on the capability to generate a desired device pattern in an image layer (photoresist) by lithography and then to transfer this pattern into the layers of materials of which the device consists.

Microwave etching device for reactive ion etching

Materials Science and Engineering: A, 1991
Abstract Electron cycloton resonance (ECR) plasmas are different from glow dischargeplasmas and introduce new complexities and possibilities. For dry etching processes (reactive ion etching), the operation in a low pressure regime and the high etch rates achievable at low ion energies,which can be controlled by an independently adjustable r.f.

Dry Etching of GaN Using Reactive Ion Beam Etching and Chemically Assisted Reactive Ion Beam Etching

MRS Proceedings, 1997
ABSTRACTDry etching characteristics of GaN using reactive ion beam etching (RIBE) were studied. Etching profile, etching rate and etching selectivity to a photoresist (PR) mask were investigated as a function of various etching parameters. Characteristics of chemically assisted reactive ion beam etching (CARIBE) and RIBE were compared at varied ...
