Depth of material removed by etch process, must be 2 .. 5 µm
2 .. 5 µm
Ambient to which substrate is exposed during processing
gold (category), copper
Pressure of process chamber during processing
Primary material removal rate divided by removal rates of secondary materials (i.e., factors by which primary material is removed faster than secondary materials)
photoresist (category): 2.78, silicon dioxide: 87.3, silicon: 1
No wafers with metal layers can be processed with this equipment.
Device that holds the wafers during processing.
List of wafer materials this tool can accept (not list of all materials, just the wafer itself).
List or range of wafer thicknesses the tool can accept
200 .. 500 µm
No metals allowed in this etcher.
Silicon dioxide masks are often used in place of photoresist masks.
