摘要：

This paper reports solutions to the problem of profile control of narrow trenches in the vicinity of wider topographic features, as well as for etching high aspect ratio, anisotropic trenches with depths in the 300-500 mum range, and of widths between 12 to 18 mum. Additionally, specific operating conditions are discussed to address uniformity variations across dies with diameters in excess of 4200 mum. (C) 2001 Elsevier Science B.V. All rights reserved.
