摘要： A system, apparatus, and method for analyzing photon emission data to discriminate between photons emitted by transistors and photons emitted by background sources. The analysis involves spatial and/or temporal correlation of photon emissions. After correlation, the analysis may further involve obtaining a likelihood that the correlated photons were emitted by a transistor. After correlation, the analysis may also further involve assigning a weight to individual photon emissions as a function of the correlation. The weight, in some instances, reflecting a likelihood that the photons were emitted by a transistor. The analysis may further involve automatically identifying transistors in a photon emission image.

摘要： A combination cooling plate and micro-spray cooling system beneficial for use in testers of electrically stimulated integrated circuit chips is disclosed. The system includes a transparent heat spreader and micro-spray heads disposed about the heat spreader. The spray heads spray cooling liquid onto a periphery of said heat spreader so as to remove heat from the chip. Alternatively, and micro-spray heads are provided inside the cooling plate holder so as to spray cooling liquid inside the interior of the holder so that the holder is cooled. The holder is in physical contact with the heat spreader, so that as the holder is cooled by the spray, heat is removed from the heat spreader, and thereby from the chip.

摘要： A system and method for automatically and accurately determining the exact location of a knife-edge, such as an edge of an optical shutter, so that it can be controlled automatically. In one aspect the system comprises a mechanized shutter coupled to a shutter controller that can automatically control the shutter's location and movement. According to one implementation of the shutter controller the system takes a first image at a first shutter position. The shutter is then moved a predetermined about and a second image is taken. Then, the pixels of each image are added in the direction perpendicular to the movement of the shutter, so as to provide two one-dimension functions. A linear difference of the functions is then taken, so as to obtain a one-dimensional linear difference function. A peak in the linear difference function is then identified as the location of the shutter.

摘要： A beacon circuit enabling study of active elements in an integrated circuit is disclosed. The beacon circuit may be integral to a DUT to be tested. The DUT is stimulated by a conventional ATE, so that its active devices are operating. The signal from the active device is sent to the beacon circuit which, in response to the signal, emits light having intensity that is proportional to the value of the signal. In one example, the beacon circuit is constructed as a voltage to current converter having its input connected to the node of interest and its output connected to a current to light converter. In one example, the current to light converter is implemented as a current mirror circuit. One beneficial implementation disclosed is the use of the beacon circuit for the study of voltage supply disturbances.

摘要： Time-resolved emission can be used to measure loop-synchronous, small-signal voltage perturbation in integrated circuits. In this technique the measurements are completely non-invasive and so reflect the true device behavior. The time-dependant propagation delay caused by Vdd modulation also shows the expected qualitative signature. This technique should find applications in circuits with relatively fast clock-like circuits where loop-synchronous voltage pickup is limiting circuit behavior.
