Abstract

Stable film resistors comprising In and Au are useful in low-temperature circuitry. In these resistors, it is desirable to provide increased resistances without altering the stability of the resistors during storage, annealing processes and thermal cycling between 4.2 degrees K and 373 degrees K.

Increasing the Resistance of In Au Resistors

Stable film resistors comprising In and Au are useful in low-temperature circuitry. In these resistors, it is desirable to provide increased resistances without altering the stability of the resistors during storage, annealing processes and thermal cycling between 4.2 degrees K and 373 degrees K.

For In-Au intermetallic compound resistors, variation of the Au concentration can be used to increase the resistance of these elements without altering their stability. In particular, the Au concentration can be increased from 46 wt. pct (AuIn(2)) to about 70 wt. pct. The sheet resistance for a 2600 angstroms thick composite film (In-Au) at 4.2 degrees K increases from 0.1 to 0.4 ohms/sq when this is done.
