WebMay 22, 2014 · The silicon is then dry etched in a process that ‘reveals’ the vias to a step height typically in the range 2-5µm. To maximize yield, it is critical that all vias are revealed to a uniform height, which can be extremely challenging if the incoming wafer thickness varies across a wafer or from one wafer to the next. WebThe titanium layer thickness was varied where the distance between the cathode and the anodes is 9 between 200-1000 A and the gold layer thickness between cm. The photoresist bath is an aqueous photo emulsion with 10 4000-5000 A. The depositions of the metal system were done wt.% solid contents.
WebThe impact of pre-CMP thermal budget on (i) CMP polishing rate, (ii) uniformity and (iii) selectivity to the underlying dielectric on bonded wafers is investigated. We further looked into other factors including incoming wafer warpage, total thickness variation (TTV) of the adhesive layer, Cu anneal process and dielectric deposition.
