!Generel description
|Drive-in of boron deposited in the boron pre-dep furnace(A1) or drive-in of ion implanted boron. Can also be used for dry and wet oxidation.
|Oxidation of gate-oxide and other especially clean oxides.
|Drive-in of phosphorous deposited in the phosphorous pre-dep furnace(A4) or drive-in of ion implanted phosphorous. Can also be used for dry and wet oxidation.
|Oxidation and annealing of 6" wafers. Oxidation of new wafer with out RCA cleaning. Annealing of wafers from the LPCVD furnaces and PECVD1.
|Oxidation and annealing of wafers from EVG-NIL, PECVD3 and wafers with aluminum.
|Oxidation of very thick oxides, thickness higher than 4 µm.
|Oxidation and annealing of almost materials on silicon wafer.
