Modular Die Stack
The new standard allows die makers to design dies which, if compliant to this standard, constitute, once stacked in a 3D-IC by a stack integrator, a consistent stack-level test access architecture. The standardization effort of the 3D-DfT design-for-test was initiated by imec.
Die stacking is commonly used in memory modules. Solder micro-bumps and through silicon via TSVs are common interconnects, and it may not viable or suitable for device that has bump pitch 10m or below. Solder interconnects have issues related to brittle intermetallic compound, solder cracked, solder merging, and long duration process if local thermos-compression bonding is adopted. Hybrid
Multi-Chip Module packaging is an important facet of modern electronic miniaturization and micro-electronic systems.
With cell phone subscribers increasing to over 5 billion, there is at least one stack-die assembly in every phone sold. Die stackingor 3D-IC packaginghas become common place among leading semiconductor manufacturers, even as the assembly houses continue to be faced with challenges as the die stacking becomes more and more complex.
Amkor's 3D stacked die technologies are widely deployed in high volume manufacturing across multiple factories and product lines.
Despite the promising advantages of 3D, there is significant concern for thermal impact. In this re-search, we study the performance advantages and thermal challenges of two forms of die stacking Stacking a large DRAM or SRAM cache on a microprocessor and dividing a traditional microarchitecture between two die in a stack.

The multi-tier die stacking approach is scalable, allowing for the stacking of two, three, or even four dies in a single package. The collective die-to-wafer bonding process, despite being complex, is designed to be more efficient by allowing wafer-level processing.
Die Stacking Die Stacking is the process of mounting multiple chips on top of each other within a single semiconductor package. Die stacking, which is also known as 'chip stacking', significantly increases the amount of silicon chip area that can be housed within a single package of a given footprint, conserving precious real estate on the printed circuit board and simplifying the board
