Abstract
A method of forming electrode at the end surface of chip array resistors utilizes the vacuum metallization technology such as sputtering evaporating deposition or ion implanting accompanying a metal mask for forming electrode at the end surfaces of chip array resistors. A blank base can be used instead of a punch-through base which has to be used in conventional technology. The method disclosed in the present invention may greatly increase the productivity of the electrodes, and at the same time, the variation of resistance value of the chip array resistor is minimized and the product quality may be improved.
