Abstract:
Thin film resistor networks can be produced in the 0.310 x 0.310 wafer size at a per resistor cost ranging between 3.5 and 3.8 cents per resistor. This is best accomplished by cutting the 0.310 wafer out of a larger wafer 1 x 1 inch or larger after the wafer has been processed through the etching step. This procedure cuts down the wafer handling cost and permits the production of the low cost resistor. The load life stability of the chromium film resistor is very good. An 0.38 average change in resistor value was obtained after 500 hours exposure to 14 watt at 125C. The copper conductor degrades this performance by oxidizing. A gold conductor was used to obtain the high stability figure. Author
