The Day Hanmi Semiconductor's Dominance Cracked: Why Hanwha Vision Became the New Star of the KOSPI 6000 Era with HBM TC Bonders
On February 24, 2026, Hanwha Vision surged 29.89% to hit the daily limit-up price and a new all-time high, driven by its subsidiary Hanwha Semiconductor's expanding HBM TC Bonder supply to SK Hynix and reports of Samsung Electronics exploring supply diversification. The stock emerged as the new superstar of Korea's semiconductor materials, parts, and equipment sector in the KOSPI 6000 era.

Why does this matter now? Hanwha Vision has entered the HBM TC Bonder market previously monopolized by Hanmi Semiconductor, and with Samsung Electronics now considering supply diversification, the landscape of Korea's semiconductor materials, parts, and equipment (MP&E) sector is being fundamentally shaken.
TL;DR
- February 24, 2026: Hanwha Vision (489790) surged +29.89%, hitting the daily limit-up price and a new all-time high (KRW 80,400) simultaneously
- Catalysts: Subsidiary Hanwha Semiconductor's expanding TC Bonder supply to SK Hynix + reports of Samsung Electronics exploring supply diversification
- Hanwha Semiconductor operating profit forecast: KRW 800M in 4Q25 → KRW 34.3B in 3Q26 (Kiwoom Securities)
- Next-gen HCB (Hybrid Cu Bonding) equipment roadmap: NAND (2026) → Foundry (2027) → HBM (2028)
- Risks: Investment overheating from the sharp short-term surge, uncertainty around Samsung Electronics order confirmation, global semiconductor CapEx volatility
The Facts: A 30% Surge in a Single Day — What Happened?
At 3:05 PM on February 24, 2026, Hanwha Vision (KOSPI 489790) hit the daily limit-up price on the Korea Exchange, closing up 29.89% at KRW 80,400 — marking a new all-time high. The stock, which opened weak in the morning, reversed higher on semiconductor tailwinds and extended its gains throughout the session to set the record.
Two catalysts converged behind the surge:
- Hanwha Semiconductor's earnings turnaround becoming visible: Hanwha Vision's subsidiary Hanwha Semiconductor supplies TC Bonders (Thermo-Compression Bonders) — the critical equipment used in HBM manufacturing — to SK Hynix. News spread in the market that the company had returned to profitability in 4Q25.
- Reports of Samsung Electronics exploring supply diversification: Exclusive reports emerged that Samsung Electronics was considering TC Bonder suppliers beyond Hanmi Semiconductor, breaking the existing monopoly arrangement. This positioned Hanwha Vision as the primary beneficiary.
On the same day, related MP&E stocks also surged sharply: Hanmi Semiconductor (+2.94%), V-RAM (+19.34%), PSK (+12.74%), and HaeSeong DS (+12.16%).
Why Did It Explode at This Particular Moment?
① KOSPI Breaks 6,000 + Semiconductor Super-Cycle Sentiment
On February 25, 2026, the KOSPI index broke through the 6,000 level, ushering in the "dream 6,000 era." With securities firms forecasting that Samsung Electronics and SK Hynix's combined operating profit would exceed KRW 300 trillion this year, a "spillover effect" spread the gains from the top-tier semiconductor names across the entire MP&E sector.
② Structural Momentum: TC Bonder Supply Chain Restructuring
The TC Bonder is the key equipment in the thermocompression bonding process used to stack HBM chips. Hanmi Semiconductor has effectively monopolized this market until now, but as HBM4E (7th generation) mass production approaches by late this year to early next year, the need for supply chain diversification has grown. Hanwha Semiconductor has moved into this gap and established itself as a major TC Bonder supplier to SK Hynix.
③ HCB Equipment: The 'Post-TC Bonder' Card
Hanwha Semiconductor is also developing next-generation HCB (Hybrid Cu Bonding) equipment. According to Park Yu-ak, analyst at Kiwoom Securities, HCB equipment is set to begin supply for NAND processes this year, then expand sequentially to foundry in 2027 and HBM in 2028. TC Bonder orders represent the short-term momentum, while HCB is the medium-to-long-term growth engine.
Context & Background: What Kind of Company Is Hanwha Vision?
Hanwha Vision was originally a security camera (CCTV) specialist. However, amid the AI semiconductor boom of 2025–2026, it expanded into the semiconductor equipment business through its subsidiary Hanwha Semiconductor. In January 2026, it was listed through a human division spin-off from Hanwha Aerospace, drawing market attention — and had already experienced one surge on January 30 (rise of semiconductor-related stocks).
Hanwha Semiconductor successfully turned profitable in 4Q25 by supplying TC Bonders to SK Hynix. Kiwoom Securities forecast the segment's operating profit to surge from KRW 800M in 4Q25 to KRW 34.3B in 3Q26.
Stakeholders: Who Wins, Who Feels the Pressure?
| Stakeholder | Impact | Direction |
|---|---|---|
| Hanwha Vision / Hanwha Semiconductor | Expanded TC Bonder & HCB orders, target price raised to KRW 90,000 | ✅ Beneficiary |
| SK Hynix | Supply chain diversification secured, HBM4E production stabilized | ✅ Beneficiary |
| Samsung Electronics | Enhanced bargaining power in TC Bonder supply negotiations | ✅ Beneficiary |
| Hanmi Semiconductor | Monopoly position threatened, potential short-term investor sentiment damage | ⚠️ Risk |
| Retail Investors | Exposed to volatility risk following sharp short-term surge | ⚠️ Caution needed |
Outlook: How Long Will This Momentum Last?
Bull case:
- The HBM market is expected to grow at double-digit rates through 2030, making TC Bonder demand structurally increasing.
- If the Samsung Electronics order materializes, earnings will level up again.
- As the HCB equipment roadmap becomes clearer, further re-rating in 2027–2028 is possible.
Warning signals:
- A 30% single-day surge is a sign of short-term overheating. Supply-demand correction may follow.
- Samsung Electronics' TC Bonder order is still "under discussion" — not a confirmed contract.
- If global CapEx volatility (Trump tariffs, economic slowdown) leads to a reduction in semiconductor investment, the entire MP&E sector could correct.
- Lifespan estimate: Short-term attention within 1–3 days + medium-to-long-term fundamental momentum maintained
