Abstract

As shown in Fig. 1, when a barrier layer, such as chrome, is not utilized between PtSi layer 10 and first level metal 11, such as aluminum, of the contacts 12 of a "P" diffused resistor body 13, the resistor without this barrier may exhibit a negative thermal coefficient of resistance (TCR).
