A family of silicon test chips for use in making diagnostic measurements during electronics assembly has been developed. These assembly test chips (ATCs) contain sensors that measure a number of variables associated with assembled IC degradation, inc

This paper describes a novel approach to background suppression termed dominant component suppression (DCS) that extends the basic concept in two ways. First, DCS adapts (via unsupervised clustering) to the major backgrounds or dominant components in

International Integrated Reliability Workshop Final Report.
A new Assembly Test Chip, ATC04, designed to measure mechanical stresses at the die surface has been built and tested. This CMOS ch@, 0.25 in. on a side, has an array of 25 piezoresistive stress sensing cells, four resistive heaters and two ring osci

Hyperspectral images have considerable information content and are becoming common. Analysis tools must keep up with the changing demands and opportunities posed by the new datasets. Many spectral image analysis algorithms depend on a scalar measure

We report the first in situ measurements of thermomechanical stresses in a 1000 I/O 250 /spl mu/m pitch piezoresistive flip chip test chip assembled to a 755 I/O 1.0 mm pitch 35 mm Ball Grid Array (BGA). The BGA substrates employed "build-up" dielect

Accelerated aging (HAST) experiments were conducted with special-purpose corrosion test chips (ATCs) in both bare die form and with various liquid encapsulants: epoxy, silicone and silicone elastomer, or silicone gel. The purpose of the experiment wa

Die cracking and stress induced damage to metal conductors in plastic package integrated circuits have become major reliability issues in recent times. Test chips with structures which can detect cracking or metal damage can be used to qualify new ty

We demonstrate the use of HAST and Assembly Test Chips (ATCs) to evaluate the susceptibility of epoxy molding compounds to moisture induced corrosion of Al conductors. We show that the procedure is sufficiently sensitive to discriminate between assem

Two devices which can be used to evaluate the ability of chip passivation or postbond coatings to protect a Si device from moisture penetration and resultant Al corrosion are described. The first device is a test chip with a number of Al triple track
