Abstract:
Replacement chemistries for the cC 4 F 8  passivation gas in the Bosch etch process and processes for using the same are disclosed. These chemistries have the formula C x H y F z , with 1≤x<7, 1≤y≤13, and 1≤z≤13. The replacement chemistries may reduce RIE lag associated with deep silicon aperture etching.

Claim (Index 1):
A method for producing apertures having different aspect ratios, the method comprising the steps of:\n a) forming an aperture having one width and an aperture having a different width in a silicon-containing substrate by plasma etching the silicon-containing substrate with an etching fluid containing fluorine to form an etched silicon-containing substrate; b) depositing a polymer film on the etched silicon-containing substrate by plasma-treating an unsaturated hydrogen-containing polymer deposition fluid selected from the group consisting of (Z)-1,1,1,4,4,4-hexafluoro-2-butene, (E)-1,1,1,4,4,4-hexafluoro-2-butene, trans-1,1,2,2,3,4-hexafluorocyclobutane, and hexafluoroisobutene; and c) repeating steps a) and b) to produce at similar rates an etched and polymer deposited silicon-containing substrate having an aperture having a high aspect ratio and an aperture having a low aspect ratio.
