Title: Thick film circuit substrate
Inventor: WATANABE MASANOBU
IPC: H01L27/01
Filed: 1983-11-11
Abstract: PURPOSE:To obtain the thick film resistor excellent in adjustment accuracy by a method wherein part of the connection between a conductor and a resistor is formed by insulation with an insulation layer, and the resistance value is adjusted toward lower values by enlargement of the resistor width by connecting the conductor to the resistor by utilizing laser heat. CONSTITUTION:A printed conductor 2 is formed on an alumina substrate 1. Next, the first layer resistor 3 is printed, and the insulation layer 4 is formed so as to cover the resistor. Finally, the second layer resistor 5 is formed so that one end is connected to the conductor layer 2, and the other end is kept distant. Thus, they are irradiated with laser heat in the direction of an arrow 6, resulting in fusion of each layer in the section, and in connection of the layers 5 and 2; then, the resistor width enlarges by moving the laser to the direction of an arrow 7. As a result, the resistance value decreases; however, the rate of decrease in resistance value becomes smaller as the laser moved distance becomes longer, and accordingly the adjustment accuracy of resistance value increases.
