  • Process optimization of CF4/Ar plasma etching of Au using

    2009-5-29In this paper, reactive ion etching of Au is performed with CF 4 /Ar gases, and process optimization method is suggested using a statistically established process model. The I-optimal design was employed to set up the etching experiment with operating parameters, namely, gas composition, RF power and chamber pressure.Its analysis was performed on individual parameters of the etch rateCited by: 8

  • Partial Pressure Analysis of CF4/O2 Plasmas | SpringerLink

    Recently, reactive low-pressure RF glow discharges (plasmas) have become indispensable tools in the fabrication of microelectronic devices. However, despite the widespread use of glow discharges, a fundamental understanding of gas-phase and surface reaction mechanisms is generally lacking.

  • Surface modification of XLPE films by CF4 DBD for

    2020-5-19Cross-linked polyethylene (XLPE) is often manufactured as pipe, film and foam products and used as electric insulation material. To improve the dielectric properties of XLPE film, CF 4 dielectric barrier discharge (DBD) is applied as a surface modification method. The surface of XLPE film was modified at the low pressure of 1 kPa with different treatment time (15s, 30s, 60s, 120s, 240s and 480s).

  • The Use of HBr in Polysilicon Etching - Pall Corporation

    2017-4-4The advantages of wet etch over dry etch are higher selectivity, higher throughput (typically multi-wafer batch - es), lower costs, and a simpler process (an immersion tank followed by rinsing and drying steps). The disadvantages are an isotropic profile and significant chemical and waste handling. Because of the isotropic profile, wet etch is
