Abstract :
High strain fields in composite structures can cause failure due to cracking of ceramic or Si or peeling of thin films. With the trend toward smaller devices/packages, geometry effects play a role through stress concentration, and it is therefore, necessary to measure strain in small areas. Examples of strain measurement on test samples from lO¿m spots, using an X-ray microdiffractometer, are given and the technique is described.
