摘要
An integrated circuit contains three thin film resistors over a dielectric layer. The first resistor body includes only a bottom thin film layer and the first resistor heads include the bottom thin film layer, a middle thin film layer and a top thin film layer. The second resistor body and heads include all three thin film layers. The third resistor body does not include the middle thin film layer. The three resistors are formed using two etch masks.
