Low Temperature Operating Life (LTOL) Test
LTOL - Reltech Limited (Reltech)
LTOL is being more used more and more frequently by manufacturers of low geometry devices as part of the qualification process, and in order to gain more failure data, a greater understanding of different failure modes of the device at low temperature, and to enable more complete reliability estimations. As device geometries decrease and frequencies become higher, Hot Carrier Injection (HCI) increases and the resulting degradation causes the deterioration of device characteristics and ultimately leads to failure.
