TSMC A16

TSMC's 3D-stacked system-on-integrated chips (SoIC) advanced packaging technologies is set to evolve rapidly. In a presentation at the company's recent technology symposium, TSMC outlined a roadmap that will take the technology from a current bump pitch of 9μm all the way down to a 3μm pitch by 2027, stacking together combinations of A16 and N2 dies. TSMC has a number of advanced packaging technologies, including 2.5D CoWoS and 2.5D/3D InFO. Perhaps the most intriguing (and complex) method is their 3D-stacked system-on-integrated chips (SoIC) technology, which is TSMC's implementation of hybrid wafer bonding. Hybrid bonding allows two advanced logic devices to be stacked directly on top of each other, allowing for ultra-dense (and ultra-short) connections between the two chips, and is primarily aimed at high performance...
