PERICOM RELIABILITY TESTING METHODOLOGY
Pericom employs a commonly used industry method to generically qualify product. It is based on the premise
that if one product of specific wafer fab/package assembly process/materials is already qualified, then a second
product that has similar design, manufacturing process, and materials can be qualified by extending the data used
to qualify the first product to the second product without generating additional data. This methodology allows
the ability to benchmark suppliers to ensure continuous process improvements and minimize cost and time
required for new product availability.
The basis of this "qualification by similarity or extension" is the following rules:
A. For Wafer Fabrication Process and Materials:
i) The wafer fabrication process technology and location are the same or similar
ii) The die array design rules and die size are the same or similar
iii) The standard and customized cell design and layout rules are the same or similar
iv) The density and complexity are the same or similar
v) The wafer fabrication materials are the same or similar
B. For Package Assembly Process and Materials:
i) The package assembly process technology and location are the same or similar
imilar
me or similar
) The package assembly materials are the same or similar
vice can only
e fabricated on one process technology/ option, and only assembled on one package type process.
ii) The die paddle to package aspect ratio is the same or smaller
iii) The package dimensions width and thickness dimensions are the same or s
iv) The leadframe/substrate design and lead/ball pitch are the sa

Where a product of interest is not sampled during this period, it is valid to use the reliability data of the particular
process technology or package type family to which the part belongs. All parts within the same family are
designed to the same rules, and manufacturing is controlled by SPC. Within a product family, a de

HCI (Hot Carrier Injection) testing is done on a test structure placed next to circuit die locations on the silicon
wafer to confirm the reliability impact of highly energetic carriers into the gate oxide
substrate, resulting in volume charge build-up that can shift transistor threshold voltages.
GOI (Gate Oxide Integrity) tests performed on a test structure by stressing the oxide using the maximum
allowable voltage across the oxide; it's comparing the measured leakage current to an acceptable limit that is
based on the ar
leakage levels.
