Sonoscan® Gives Details of Stacked Die Tool!
Elk Grove Village IL -- September 10, 2009 -- Sonoscan has unveiled some of the details that enable its powerful new software tool to perform acoustic imaging to identify anomalies and defects in stacked die configurations. The software, announced in August, is already being used in the headquarters SonoLab® to solve stacked die problems for client companies.
"The question most often asked is, How many die can you image in one stack?" reports SonoLab manager Ray Thomas. The number that is typically mentioned is four or more die, but SonoLab personnel have also been able to image all of the interfaces in a stack of eight die.
"Imaging eight die," Thomas adds, "may not be feasible in every case. Imaging is generally more successful when SonoLab personnel have good data about the dimensions and geometry of the stack."
The key problem is that ultrasound pulsed into the stack by the C-SAM® system's transducer is reflected from such a large number of internal interfaces. If there are eight die, then there are at least 17 interfaces and numerous multiple reflections.
The real value of the new software is that it can sort out the right echoes and provide the acoustic imaging accuracy that lets manufacturers build high reliability into their die stacks.
