The Advanced Memory Essentials (AME) deliverable for DRAM chips comprises a concise analyst’s summary document highlighting observed critical dimensions and salient features supported by the following image folders:

Downstream product teardown

Package X-rays, top metal and poly die photographs, non-invasive optical photos of die features

SEM bevel through the logic region and DRAM

SEM cross section of the general device structure, BEOL (metals, dielectrics) and FEOL structures

Two or three TEM cross sections, orthogonal to the word and bit lines, and possibly active directions of DRAM array, showing the DRAM capacitor array , lower metals and dielectrics, transistor gates, isolation, and other FEOL features

The results of TEM-EDS analyses are included in the AME summary document. The AME deliverable provides timely competitive benchmarking information and enables cost-effective tracking of technical innovation across a breadth of competitors
