不做 英特尔（INTC.US）
事件处于'据报考虑'最早期阶段，SK海力士已部分否认（'部分报道不实'）；即使属实，HBM4E基础芯片代工收入相对英特尔市值极小且量产在2027年+，属远期叙事非近期催化；盘中冲高+2.6%已回落至+0.5%，短线edge已消失；stock_quote无法取得实时报价，不满足ENTER价格验证前提
不做 台积电（TSM.US）
事件未确认且时间极远（HBM4E 2027年+），台积电HBM基础芯片代工整体仍在增长，不构成做空催化；不满足做空红线①明确强空催化

结论摘要
TrendForce转引韩国Herald Business报道SK海力士考虑将HBM4E基础芯片部分代工转向英特尔，但SK海力士回应称'部分报道不实'。事件处于最早期的'据报考虑'阶段，无设计定点、订单或收入里程碑。modeling_kb确认HBM4基础芯片代工格局为SK海力士/美光→台积电、三星→自家SF4，HBM4E量产在2027年+。即使英特尔获得部分代工份额，收入相对其~2000亿美元级市值极小。英特尔盘中一度涨至+2.6%后回落至+0.5%，表明市场已消化或对该传闻不以为然。无A股映射标的。综合判断：方向不明、证据不足、无可执行edge，不做。

[News] SK hynix Reportedly Weighs Intel for HBM4E Base Dies amid TSMC Cost Pressure and Supply Diversification
As Intel pushes to expand its foundry footprint beyond its own chips—from advanced packaging (EMIB) to logic manufacturing—memory makers may be exploring a similar diversification away from TSMC. With the base die becoming a key differentiator in the HBM4 era, SK hynix is reportedly considering Intel Foundry for part of its base-die production starting with HBM4E, according to Herald Business.
The move, if confirmed, could also help ease mounting cost pressures. Herald Business estimates that TSMC’s HBM4 base dies could already cost 3–4 times more than SK hynix’s core dies built on its 1b process, with the gap expected to widen for HBM4E.
Passing those higher foundry costs on to customers, however, could prove difficult given the high share of long-term supply agreements (LTAs) in HBM. Bringing Intel into the base-die supply chain could therefore give SK hynix greater flexibility in managing costs while improving supply stability, the report adds.
SK hynix produced base dies in-house through HBM3E, but turned to TSMC for HBM4 as the dies took on greater logic and performance demands, Herald Business explains, adding that its HBM4, now in mass production, uses base dies made on TSMC’s 12nm-class process.
Beyond manufacturing, SK hynix is also expanding its base-die design capabilities. According to NewsPim, SK hynix America operates an HBM Architect Design Team in San Jose, California, working directly with major U.S. customers on base-die designs for HBM and 3D-stacked DRAM.
Responding to the Herald Business report, SK hynix said it was difficult to confirm details related to its technology roadmap and that “some of the reports are not true.”
Base Die: The New HBM Battleground
Interestingly, Business Post notes that if Intel proves it can deliver HBM base dies to SK hynix at competitive yields and costs, Samsung Electronics and Micron could also consider tapping Intel.
Either way, base dies are emerging as a key focus for memory makers. S-Journal notes that Samsung manufactures HBM4 base dies in-house on its 4nm foundry process, integrating the core DRAM, logic die and advanced packaging.
Notably, strong demand for HBM base dies is already lifting Samsung’s foundry business. The company said in its July 30 earnings release that rising HBM4 shipments and stronger demand for HBM base dies from customers in the Americas helped improve foundry revenue and performance.
Micron, by contrast, continues to use 1-beta DRAM for HBM4 memory dies and is expected to move to 1-gamma DRAM with HBM4E. Like SK hynix, its logic dies for both standard and custom HBM4E are also expected to be manufactured by TSMC.
