A better uniformity of the resistivity across the wafer was achieved by subsequently annealing in N<sub>2</sub>, the annealing was done in Anneal Oxide Furnace (C1). | A better uniformity of the resistivity across the wafer was achieved by subsequently annealing in N<sub>2</sub>, the annealing was done in Anneal Oxide Furnace (C1). The measured film thickness was 370 nm and the sheet resistance was measured to 200 Ω/sq +/- 15 Ω/sq. | ||
