5. This device is very thin device and should be handled with caution for mechanical stress. The rate of distortion
Note 1. Definition of rate of distortion (written as ε in this document)
applied to the device should become below 2000
characteristic of a device may be degraded and it may result in failure.
2. The relation of the distortion and the bend changes with several conditions, such as a size of substrate and
so on.
ε = (l − l
