韩国 DB HiTek 完成 1200V SiC MOSFET 可靠性验证、11 月交付第三代 PDK，8 英寸碳化硅代工拟明年上半年量产（初始仅 800 片/月）
事件本身为正面的技术/供给能力里程碑，但缺乏需求验证与金额增量：无订单、无客户点名、无收入或指引，量产要到明年上半年，初始产能仅 800 片/月（占该厂 1.3%），对 DB HiTek 收入与市值的短期弹性可忽略。时间上消息于 2026-09-09 10:11 UTC（约 19:11 KST，韩股已收盘）发出，至 now 2026-09-14 08:47 UTC（17:47 KST 盘后）已经过 9/10、9/11、9/14 三个完整交易日的消化窗口，下一个可执行时段（9/15 开盘）交易的是 4 天前旧闻且无任何新增事实；二阶 A 股/港股 SiC 衬底与外延映射既量级不足也无关系证据。故整体不做。

结论摘要
事实：The Elec 引述 DB HiTek 9 月 9 日口径，公司完成 1200V SiC MOSFET 可靠性验证、11 月交付第三代 PDK（比导通电阻 2.3 mΩ·cm²、耐 2.5μs 短路）、明年上半年量产，初始 800 片/月，为上友园区 63,000 片/月产能的 1.3%，全文无订单金额、客户名单或收入指引，竞争对手 SK keyfoundry 同期量产。影响链：PDK 与可靠性验证只证明供给能力与设计生态就绪，需求验证（设计导入、绑定采购、backlog）尚未出现；即使明年顺利量产，800 片/月折算约 9,600 片/年，对 DB HiTek 的收入与利润弹性在短期内属可忽略量级，对上游衬底/外延供应商同样不构成有意义的增量需求。价格与证据：001830.KS 本轮实时报价与日线均取不到（yfinance 无报价、price_snapshot 无数据），无法量化 9/10–9/14 的重定价，但时间维度已明确——首发落在韩股收盘后，三个完整交易日已消化，下一个可下单时段交易的是旧闻；Web 搜索后端本轮返回噪声，官方 IR 原文与韩媒扩散未能二次核实，FactSet/Wind 关系表对 001830.KS 无覆盖。结论：软技术里程碑 + 量级不足 + 反应窗口已过，无正期望入场结构，AVOID；无净利空，故不输出风险信号，也不开空。

消息传播链
- 垂直行业媒体首发，正文写明 “DB HiTek said Sept. 9”，即公司当日对外披露；10:11 UTC 对应 19:11 KST，晚于韩股 15:30 收盘，因此价格反应只能落在 9/10、9/11、9/14 三个交易日市场反应:无法核验：001830.KS 本轮 stock_quote 返回 no_price（yfinance 无报价）、price_snapshot 返回 no_data
- 2026-09-09官方确认/否认DB HiTek 官方 IR/新闻稿（未在本轮工具结果中取得链接）非一手转述称公司发布官方口径，但本轮 Web 搜索后端连续返回无关结果，未能定位官方原文，故按“未核验”处理，不作为独立一手节点
- 距首发约 5 天、3 个完整交易日，韩国、A 股、港股、美股均不在可成交时段（美股为盘前）；下一可执行时段交易的是无新增事实的旧闻
主要风险
- 若后续披露绑定客户、订单金额或产能大幅上修，则本判断需要重估（当前无任何金额与客户信息）
- 001830.KS 行情本轮取不到，无法用真实价格与量能验证是否已提前抢跑或已见光死

先例如何影响了这次决策
对本次决策的影响:先例缺失不改变结论：即便存在正向先例，本事件的量级（800 片/月≈该厂产能 1.3%）与已过的反应窗口仍不足以支撑 ENTER；因此未提交 event_study，避免用低相似样本污染定价
方向:无可溯源先例，方向判断改由事件阶段（技术里程碑 vs 需求验证）与量级测算承担
涨幅量级:无高相似、锚点干净的先例可用于校准 tp/sl；本条亦未给出任何可校准幅度，故不设价格目标
形态:无先例数据，无法评估该类特种代工技术里程碑是否反复见光死；但首发落在收盘后且已过三个交易日，追高风险由时间维度而非先例支持

DB HiTek is in the final stages of preparing for mass production of its 8-inch silicon carbide (SiC) wafer foundry business.
DB HiTek said Sept. 9 that it had completed reliability verification of a 1,200-volt SiC MOSFET. The company plans to provide customers with its third-generation process design kit (PDK) in November as it moves to launch its foundry business.
The third-generation PDK targets specific on-resistance of 2.3 mΩ·cm² at an 18-volt gate voltage, down from 2.5 mΩ·cm² for the second generation. It is also designed to allow the device to withstand a sudden short circuit for 2.5 microseconds without damage. DB HiTek said the third-generation PDK could shorten semiconductor design time by more than a year.
“We have secured the core technology and mass-production foundation for what will be the world’s first 8-inch SiC foundry service,” DB HiTek said. “We will prepare for mass production as planned and move to establish an early lead in the market.”
Mass production is targeted for the first half of next year. Rival SK keyfoundry is also expected to begin mass production of 8-inch SiC foundry products in the first half of next year. SiC foundry operations require production lines to be developed and established jointly with customers, meaning both companies have effectively secured customers ahead of mass production. Samsung Electronics also has an 8-inch SiC production line, but does not offer it to external foundry customers.
The SiC semiconductor market currently centers on 150-millimeter wafers, while mass production using 200-millimeter wafers remains rare globally. SiC semiconductors use specially processed wafers that differ from conventional silicon (Si) wafers. Due to the technology’s lower maturity, production yields for 200-millimeter SiC wafers are lower than for 150-millimeter wafers, resulting in lower output.
DB HiTek will operate its SiC foundry at its Sangwoo Campus in Eumseong, North Chungcheong Province, converting the current development line into a mass-production line. Initial capacity will be relatively small at 800 wafers a month, about 1.3% of the Sangwoo facility’s total monthly capacity of 63,000 wafers. The company has established an integrated process covering design, manufacturing, characterization, reliability verification and epiwafer supply.
For now, DB HiTek is operating the development line primarily for customers it has already secured. It plans to add customers after establishing the mass-production system and gradually expand capacity in line with market demand.
