The extensive use of thin films in the manufacture of microelectronic
devices and for protection against wear and corrosion has stimulated c
onsiderable interest in their mechanical properties. In this review th
e most widely used testing methods of free standing films and of films
adherent to their substrates are described. Particular attention is g
iven to problems and difficulties experienced with each of the techniq
ues. Results obtained by these methods are discussed and critically ex
amined.
