Semiconductor Equipment 半导体设备 반도체 장비
Lithography, etch, deposition, inspection, and advanced packaging tools.
Why AI demand reaches this layer · 需求为什么传导到这里 · 수요가 여기까지 오는 이유
Wafer demand converts into tool demand: lithography, etch, deposition, inspection, and the advanced packaging steps that bond HBM stacks to logic. Equipment sits two steps removed from AI headlines and one step ahead of capacity.
晶圆需求最终转化为设备需求：光刻、刻蚀、沉积、检测，以及把 HBM 堆叠与逻辑芯片键合的先进封装环节。设备离 AI 的新闻标题隔了两步，却比产能早一步。
웨이퍼 수요는 장비 수요가 된다: 노광, 식각, 증착, 검사, 그리고 HBM 스택을 로직에 붙이는 첨단 패키징. 장비는 AI 헤드라인에서 두 걸음 떨어져 있고, 용량보다 한 걸음 앞이다.
Where the chokepoint sits · 瓶颈在哪 · 병목은 어디인가
Some steps have effectively one supplier worldwide. Advanced packaging capacity, not wafer starts, has repeatedly been the limit on how many accelerators can ship.
某些工序全球实际上只有一家供应商。而限制加速器出货量的，多次是先进封装产能，而不是晶圆投片量。
어떤 공정은 사실상 전 세계에 공급사가 하나다. 가속기 출하를 반복해서 막은 것은 웨이퍼 투입이 아니라 첨단 패키징 용량이었다.
A structural observation about supplier concentration and lead times — not a view on any security. 这是关于供应商集中度与交期的结构性观察，不是对任何标的的看法. 공급사 집중도와 납기에 대한 구조 관찰이지, 어떤 증권에 대한 의견이 아닙니다.

Public 13F filings citing these securities · 引用这些标的的公开 13F 申报 · 이들 증권을 인용한 공개 13F
Research context, not a recommendation. These are facts on file with the SEC; the classification that puts a security in this layer is ours, and the filer made no such claim.
供研究参考，不构成任何推荐。以下是已向 SEC 存档的事实；把某个标的归入本层级是我们的分类， 申报人并未作出这样的表述。
- ARK Investment Managementreported a position inTERForm 13F-HR for the period ending 2026-06-30, filed 2026-08-14 · SEC filing
- Bridgewater Associatesreported a position inTERForm 13F-HR for the period ending 2026-06-30, filed 2026-08-14 · SEC filing
Rows below are public SEC Form 13F-HR filings, reported by the filing entity for the period shown and filed later — they are never current holdings. Form 13F covers long US equity positions only: it excludes short positions, cash, non-US holdings and most derivatives, and a reported position may have been sold since. Assigning a ticker to a layer is XingAI's classification, not the filer's. Nothing here is a recommendation, and an institution reporting a position is not a reason to take one.
下列条目来自 SEC 公开的 Form 13F-HR 申报，由申报主体就所示期间申报、并在其后提交 —— 它们不是当前持仓。Form 13F 仅覆盖美股多头头寸：不含空头、现金、非美资产和大多数衍生品，且申报的头寸可能已被卖出。把某个标的归入某一层级是 XingAI 的分类，不是申报人的。此处没有任何推荐，机构申报持有某标的也不构成你持有它的理由。
