A tungsten (W) etch process in a SF6 helicon plasma has been modeled using neural networks. The process was characterized by a 24−1 fractional factorial experimental design. The design factors that were varied include source power, bias power, chuc

The formation mechanism of tungsten (W) atoms in tungsten etching has been investigated with the SF 6 /Ar helicon plasma. The etch rate of W films decreases with increasing flow rate of Ar in the SF 6 /Ar gas mixture while the density of tungsten ato

Etching of the bottom resist layer in a tri-level resist (TLR) process has been investigated in a magnetically enhanced reactive ion etcher (MERIE). It was found that the addition of Ar to an O 2 plasma is effective for obtaining an anisotropic etch

Using a pulsed-power inductively coupled plasma technique, etching characteristics for a SiO/sub 2/ film were investigated and applied to control the ferroelectric performance degradation induced by plasma etching when a ferroelectric capacitor struc

The effects of reactive ion etching damage on the electrical properties of Pt/SBT/Pt capacitors have been investigated. The plasma treated SBT/Pt layers showed a significant decrease in remanent polarization compared with that of the reference sample

Lead-Zirconate-Titanate (PZT) films were etched with CF4/Ar mixed gases in high-density plasmas. Etch characteristics of the PZT film were investigated by using in-situ plasma diagnostic tools in conjunction with the surface analysis after etching. D
