Advanced packaging exists on a continuum of cost and throughput vs performance and density. Even though the demand for advanced packaging is obvious, there is an incredible number of advanced packaging types and brand names from Intel (EMIB, Foveros, Foveros Omni, Foveros Direct), TSMC (InFO-OS, InFO-LSI, InFO-SOW, InFO-SoIS, CoWoS-S, CoWoS-R, CoWoS-L, SoIC), Samsung (FOSiP, X-Cube, I-Cube, HBM, DDR/LPDDR DRAM, CIS), ASE (FoCoS, FOEB), Sony (CIS), Micron (HBM), SKHynix (HBM), and YMTC (XStacking). These packaging types are used by all of our favorite companies from AMD, Nvidia, and many more. In Part 2, we will explain all these types of packaging and their uses.Read more
SemiAnalysis has been hearing murmurings about TSMC’s N3 having poor yields, poor metal stack performance, being very expensive, and being too late for Apple’s 2022 iPhone. These can’t be confirmed, but we can confirm that TSMC N3 is now shipping in Q1 2023.
The hiccup on N3 brings many questions about TSMC’s competitive positioning versus Intel 20A and Samsung 2nm. Both these nodes are very aggressive and aimed at getting back into a competitive position against TSMC. Intel and Samsung even claim the nodes will bring leadership.
YMTC 128 Layer NAND is the first semiconductor where China is technologically competitive with the leading edge firms from the Western sphere of influence.
Yields are improving and the 2nd fab is being filled with equipment. Once that milestone is reached, the 3rd and 4th fab will be built simultaneously.
