A practicing semiconductor engineer's daily read on global silicon news:
TSMC is taking its most two-sided hit in 30 years — AMD's next-gen 2nm order went to Samsung (DIGITIMES 5/11 exclusive), and SK hynix is piloting its own HBM paired with Intel EMIB 2.5D packaging on an R&D line. Meanwhile Korea's May 1–10 semi exports spiked +149.8% to 46.3% of total exports, Kiwoom officially called a 100T KRW Samsung 2Q OP, and the Samsung union is threatening an 18-day strike from 5/21 demanding SK hynix-style $900K annual payouts — an $11.7B loss scenario.
Chase's Take — I've never seen TSMC's foundry+packaging double-grip shaken on both sides in a single week. AMD handing 2nm to Samsung because of the US-bound capacity shortfall from the N-2 rule is the biggest supply-chain reshuffle since GF abandoned 7nm in 2018, and SK hynix putting EMIB on an evaluation line reads as the end of the CoWoS-only era. That said, Intel EMIB-T yield at 90% trails CoWoS-L at 98% by 10pp — in logic+HBM packages that gap directly sets packaging margin. So EMIB will likely land as a capacity hedge, not the main line, and Google TPU v8e (2027 H2) and next-gen Meta MTIA are the first real validation window. Korea's +149.8% memory-only export print is both a trigger for BoK to raise Q2 GDP consensus again and a boomerang that just supercharged the Samsung union's wage leverage. Three watch-points next: 5/13 Cisco Q3 AI orders ($1.5B+ consensus), 5/14 AMAT Q2 FY26 EUV/HBM-step WFE guide, and whether the Samsung strike actually starts on 5/21.
1. AMD's 2nm defection to Samsung dents TSMC's AI grip

TL;DR — AMD has placed its next-gen 2nm volume order with Samsung Foundry rather than TSMC. The US fabless single-supplier hedge — already in motion at Tesla and Google — now extends to AMD.

2. SK hynix reportedly tests Intel EMIB 2.5D packaging with HBM amid TSMC CoWoS tightness

TL;DR — SK hynix is running an R&D line pairing its own HBM with Intel EMIB-based 2.5D packaging. TSMC CoWoS capacity tightness is now rattling the memory-logic vertical-integration paradigm.

3. MediaTek denies Intel link as TSMC's packaging lead faces new test

TL;DR — Douglas Yu (the father of CoWoS) joining MediaTek as a consultant sparked rumors of a Google TPU EMIB bridge, but MediaTek officially denies it. The decisive variable is a 10pp packaging-yield gap.

4. Korea's early-May semi exports +149.8% — 46.3% of total exports, memory carrying the load

TL;DR — Korea Customs (5/11): May 1–10 total exports hit $18.4B (+43.7% YoY), an all-time high; semiconductors alone delivered $8.54B (+149.8%), a record for the early-May window. The memory super-cycle is now landing in clearance data.
5. KOSPI 10,000 / Samsung 500K / SK hynix 3M targets all raised — Money Today 5/11

TL;DR — JPMorgan reset its KOSPI scenarios on 5/11 (bull 10,000 / base 9,000 / bear 6,000). SK Securities' 500K Samsung and 3M SK hynix targets are landing as market signals — SK hynix hit a new intraday high and crossed $900B in market cap.

6. Kiwoom: Samsung 2Q operating profit 100T KRW, target raised to 330K KRW

TL;DR — Kiwoom Securities (5/11) lifted its Samsung Electronics target from 260K to 330K KRW (BUY). Analyst Park Yu-ak models 2Q revenue of 181T KRW and OP of 100T KRW — with the foundry segment also flipping to profit.

7. Samsung chip workers reject $340,000 bonus — demand SK hynix-style $900,000, 18-day strike could cost $11.7B

TL;DR — The Samsung union rejected a $340,000 one-time bonus and is demanding the SK hynix-style $900,000 annual payout. A 5/21–6/7 18-day strike would cost an estimated $11.7B — colliding head-on with Big Tech's $725B 2026 capex cycle.
8. Cisco Q3 FY26 earnings preview: AI orders + Splunk test

TL;DR — Cisco reports Q3 FY26 after close on 5/13. Revenue guide $15.4–15.6B (above $15.2B consensus), AI orders annual $5B+ raised, Silicon One G300 (102.4 Tbps) starting to land in revenue — options imply a ±8.71% move.
