马斯克:Fab里面要能抽烟!
是说芯语· 2026-01-08 05:03
这位亿万富翁曾经提议特斯拉建立自己的芯片制造网络,并满足公司的定制芯片需求,随后,特斯 拉与三星就AI5和AI6芯片展开了广泛的合作。而现在,他又透露,特斯拉计划打造TeraFab工厂以 生产2纳米芯片。 尽管这一说法听起来激动人心,但考虑到特斯拉在芯片制造领域毫无经验,TeraFab更可能会是特 斯拉与其他合作伙伴的一次进阶合作。 据报道,马斯克声称特斯拉拟建的 TeraFab 超级工厂将具备生产 2nm 制程芯片的能力。更为颠覆的 是,马斯克对芯片制造行业的"洁净室"(Cleanroom)标准发起了挑战,并立下赌约称:"特斯拉将拥有 2nm 工厂,而我甚至可以在里面一边吃汉堡、一边抽雪茄。" 在现代晶圆厂里,洁净室是芯片生产设施不可或缺的一部分,因为它们负责控制可能影响芯片良率 的污染颗粒。 像台积电这样的公司每年投入数十亿美元,在芯片生产设施内打造受控环境,例如集成HEPA/ULPA 过滤设备,并确保所有操作人员都穿着全身防护服。 针对如何防止汉堡油脂和烟尘污染硅片的问题,马斯克给出了他的解决方案"晶圆隔离"(wafer isolation)。他主张将保护重点从整个房间缩小到晶圆本身,确保晶圆在所有加工 ...
马斯克确认:将建2nm晶圆厂!但他想在里面抽雪茄、吃汉堡!

现代晶圆厂是一个大型的、一体化的制造设施,包括超洁净的生产洁净室(用于晶圆加工);设有真空泵、气体处理和排气系统;用于维护和公用设施的 专用工具服务走廊;集中式化学品输送和废物管理基础设施;以及用于行政工作、工程和监控的办公和控制区域。 同时,洁净室本质上是晶圆厂建筑内的独立单元,因为它们与晶圆厂外壳的其他部分完全隔离。洁净室的洁净度由ISO 等级标准规定,该标准定义了不同 粒径的颗粒每立方米空气中的颗粒数量。例如,ISO 1 级洁净室每立方米空气中最多允许 10 个 ≥0.1 µm 的颗粒和 2 个更大的颗粒;而 ISO 2 级洁净室每立 方米空气中最多允许 100 个 ≥0.1 µm 的颗粒和 38 个更大的颗粒。晶圆制造最关键的操作——例如 EUV 或 DUV 光刻曝光或先进的栅极形成——都在 ISO 1 级和 2 级洁净室中进行。相比之下,ISO 3 级洁净室每立方米空气中最多允许 1000 个 ≥0.1 µm 的颗粒,这仍然比典型的晶圆厂环境洁净得多,并且通常 用于对洁净度要求不高的操作的先进晶圆厂。 显然,当前在光刻等核心环节所需的ISO 1-3级洁净室环境中吸烟或吃汉堡是绝对禁止的,因为这会产生 ...
寻重大工程“足迹”,挖产业转型“宝藏”

Core Viewpoint - The construction industry is expected to experience a shift in investment dynamics due to policy stimuli and emerging themes, with private enterprises showing significant returns compared to state-owned and central enterprises [1][2]. Group 1: Market Performance - As of November 30, 2025, the SW Construction Decoration Index increased by 8.88%, while the CSI 300 Index rose by 18.19%, indicating that the overall performance of the construction sector lagged behind the broader market [2]. - Private enterprises achieved a return of 35.6%, while local state-owned enterprises had a return of 14.96%, closely aligning with the CSI 300 Index. In contrast, central state-owned enterprises faced a significant decline with a return of -4.51% [2]. Group 2: Future Investment Outlook - The first year of the 14th Five-Year Plan is anticipated to open an investment uptrend, as historical patterns suggest that the initial years of a five-year plan typically see heightened investment intensity [2]. - Major planning and project packages are expected to be implemented in 2026, potentially leading to a new cycle characterized by "high initial growth followed by stabilization" [2]. Group 3: Value Investment Themes - Three main value investment themes are identified: 1. Key projects such as the Pinglu/Zhejiang-Jiangxi-Guangdong Canal (total investment approximately 621.1 billion), the Tibet Railway (expected total investment over 700 billion), and the Yaxi Hydropower Project (total investment around 1.2 trillion) are projected to generate long-term orders [3]. 2. High dividend yields are emphasized as regulatory measures strengthen dividend constraints, enhancing the investment appeal of low-valuation, high-dividend construction firms [3]. 3. Growth transformation opportunities in new sectors like clean rooms, AI computing infrastructure, and low-altitude economy are expected to surge, with cash-rich private enterprises likely to pursue mergers and acquisitions for rapid entry [3]. Group 4: Stock Recommendations - Specific stocks to watch include Sichuan Road and Bridge (600039), Jianghe Group (601886), Honglu Steel Structure (002541), Jinggong Steel Structure (600496), and Pudong Construction (600284) [3].
