The HTOL test is typically applied on logic and memory devices. The HTFB test is typically applied on power devices, diodes, and discrete transistor devices not typically applied to integrated circuits.

Reliability Tests for Semiconductors

JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. The HTGB test is typically used for power devices.

The information included in JEDEC standards and publications represents jesd222 sound approach to product specification and application, principally from the solid state device manufacturer viewpoint.

Depending upon the biasing configuration, supply and input voltages may be grounded or raised to a maximum potential chosen to ensure a stressing temperature a08 higher than the maximum-rated junction temperature. Jesd2 a device has a thermal shutdown feature it shall not be biased in a manner that could cause the device to go into thermal shutdown.

All specified electrical measurements shall be completed prior to any reheating of the devices, except for interim measurements subject to restrictions of clause 6. Device outputs may be unloaded or loaded, to achieve the specified output voltage level.

Uesd22 particular bias conditions should be determined to jerec the maximum number of potential operating nodes in the device. The particular bias conditions should be determined to bias the maximum number of the solid state junctions in the device. The detailed use and application of burn-in is outside the scope of this document.


The devices may be operated in either a static or a pulsed forward bias mode. What Do You Meme? The HTRB test is typically applied on power devices. Typically, several input parameters may be adjusted to control internal power dissipation.

However, testing at elevated temperatures shall only be performed after completion of specified room and lower temperature test measurements. This and the high temperature testing restrictions of this clause need not be met if verification data for jssd22 given technology is provided. After an interim measurement, the stress shall be continued from the point of interruption.

Interim measurements may be performed as necessary per restrictions in clause 6.

To eliminate units with marginal defects that can result in early life failures. Interim and final measurements may include high temperature testing. This document is copyrighted by the Electronic Industries Alliance and may not be reproduced without permission.

Electrical testing shall be completed as soon as possible and no longer than 96 hours after removal of bias from devices. After interim testing, bias shall be applied to the parts before heat is applied to the chamber, or within ten minutes of loading jedce final parts into a hot chamber. A higher voltage is permitted in order to obtain lifetime acceleration from voltage as well as temperature; this voltage must not exceed the absolute maximum rated voltage for the device, and must be agreed upon by the device manufacturer.

NOTE If the devices have been removed from bias and the 96 hour window is not met, the stress must be resumed prior to completion of the measurements. By downloading this file the individual agrees not to charge for or resell the resulting material.

The LTOL test is intended to look for failures caused by hot carriers, and is typically applied on memory devices or devices with submicron device dimensions. Pulsed operation is used to stress the devices at, or near, maximum-rated current levels. To eliminate units with marginal defects that can result in early life failures; To determine the high temp operating lifetime of a population. NOTE Bias refers to application of jes2d2 to power pins.


The devices are normally operated in a static mode at, or near, maximum-rated oxide breakdown voltage levels. The duration of this stress shall be 24 hours for any portion of each week the limit is exceeded i. Jesdd22 devices may be operated in a dynamic operating mode. To determine the high temp jedce lifetime of a population. To determine the resistance of a part to extremes of high and low temperatures; as well as its ability to withstand cyclical stresses.

To determine the resistance of the part to sudden exposures to extreme changes in temperature and alternate exposures to these extremes; as well as its ability to withstand cyclical stresses. A form of high temperature bias life using a short duration, popularly known as burn-in, may be used to screen for infant mortalityrelated failures.

JEDEC standards and publications are adopted without regard to whether or not their adoption a180 involve patents or articles, materials, or processes. No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met.

The interruption of bias for iedec to one minute, for the purpose of moving the devices to cool-down positions separate from the chamber within which life testing was performed, shall not be considered removal of bias.

To determine the ability of the part to withstand the customer’s board mounting process; also used as preconditioning for other reliability tests. NOTE Manufacturers may also specify maximum case temperatures for jesec packages.
