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 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-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.

Role of ions in reactive ion etching

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1994
Energetic ion bombardment is responsible for the anisotropic etching which can be obtained in reactive ion etching. This has been recognized for many years but the detailed mechanisms involved in this process are still not well understood. In this paper, the various phenomena resulting from ion bombardment of a surface in a reactive gas glow discharge ...

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 ...

Kinetics of Reactive Ion Etching of Polymers in an Oxygen Plasma: The Importance of Direct Reactive Ion Etching

MRS Proceedings, 1993
AbstractThe etching of polymer films in oxygen-based plasmas has been studied between 5 and 100 mTorr in a reactive ion etch reactor using Langmuir probe and optical actinometry measurements. Results for the etch yield (the number of carbon atoms removed per incident ion) are analyzed in terms of a surface-chemical model for ion-enhanced etching ...

Reactive ion etching for failure analysis applications

30th Annual Proceedings Reliability Physics 1992, 1992
An attempt to develop and to optimize reactive ion etch processes for failure analysis applications is discussed. Reactive ion etching (RIE) provides several advantages over wet and plasma etching. Delayering of interlevel dielectric and passivation films with RIE results in anisotropic sidewalls.
