High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at … See more The main aim of the HTOL is to age the device such that a short experiment will allow the lifetime of the IC to be predicted (e.g. 1,000 HTOL hours shall predict a minimum of "X" years of operation). Good HTOL process shall … See more Sample selection Samples shall include representative samples from at least three nonconsecutive lots to represent manufacturing variability. All test samples shall be fabricated, handled, screened and assembled in the … See more The aging process of an IC is relative to its standard use conditions. The tables below provide reference to various commonly used products and the conditions under which they are used.
