ABSTRACT:
An insulating film with low thermal expansion characteristics is formed by depositing aluminum alloy materials in thin film form without the use of high temperatures and which can then be oxidized to create an insulating film which has low stress. A mixture of aluminum and magnesium oxides, known as spinel, has the proportions which are approximately correct for zero expansion when crystallization results from the oxidation.
