WebAbstract: Significant amounts of micromasking residue have been observed at the interface between a Ti-containing ARC layer and a PE-TEOS hardmask after the hardmask has been etched and prior to the use of the etched hardmask for transferring a pattern to an underlying metal layer (e.g., aluminum). The micromasking residue can interfere with … WebNov 20, 1992 · A furnace, CVD TEOS-based oxide, and a plasma enhanced TEOS-based oxide were evaluated for use as spacer oxides in a deep trench.

WebTEOS are observed (fig. 7). Compared to planar capacitors with top and bottom noble metal electrodes the PZT I thin A1203 stack is very simple and can be etched with high taper angle (U0) as shown in fig. 8. The TEOS hardmask taper is transformed to the PZT during reactive ion etching (RIE). Optimizing the hardmask
