如果您希望可以时常见面，欢迎标星收藏哦~ 被视为"终极半导体"的金刚石，正站在产业化最关键的十字路口。 从性能上来讲，金刚石拥有出色的散热能力、宽禁带等优势，理论上能完美解决芯片发热的世纪难 题，支撑人工智能、高功率雷达等前沿科技走向下一个世代。 然而，当学术界的赞誉归于平静，产业界的疑问开始浮现：这颗材料领域明珠，为何迟迟无法照亮 生产线的现实？2025企创融通汇宽禁带半导体材料专场活动中，来自学界业界的专家们就这一问 题进行了深入讨论。 首先，制造大尺寸、高质量的单晶金刚石非常昂贵。"金刚石在半导体应用方面的难点，第一个是 材料制备本身，真正的挑战在于如何实现低成本化。"西安电子科技大学教授任泽阳表示。同时， 如何有效地在金刚石中进行"掺杂"让其变为能被精准控制导电性的半导体材料，仍然是一个基础科 学难题。任泽阳认为，这需要从材料物理角度寻求新的掺杂机制。 加工金刚石本身也是一个难题。金刚石是硬度最高的材料，切割和打磨它消耗巨大。上海征世科技 股份有限公司教授级高工尹利君表示，切割一片25毫米见方的晶片，材料损耗就可能超过1毫米， 这对于本身就很薄的衬底来说成本很高。美国国家发明家科学院院士、杭州银湖激光 ...

金刚石散热专题报告：高效散热材料，商业化进程持续推 进 20251230 摘要 金刚石材料因其卓越的热导率（是铜的 5 倍，铝的 10 倍）和热扩散系 数，能够有效降低芯片结温，尤其适用于处理单元高度集中的 AI 芯片， 并已在射频功率放大器及高功率激光二极管等领域实现部分商业化应用。 阿帕奇公司的钻石冷却技术可以将 GPU 热点温度降低 10~20 度，风扇 速度降低 50%，超频能力提高 25%，服务器寿命延长一倍，从而节省 数据中心数百万美元冷却成本，验证了金刚石在散热方面的巨大潜力。 金刚石材料主要分为单晶金刚石、多晶金刚石以及复合材料（如金刚石 铜、金刚石铝），其中多晶金刚石因成本较低、制备速度快，更适合作 为当前阶段经济型散热材料。 金刚石铝密度低于金刚石铜，适用于对重量敏感的应用场景，如航空航 天和便携式高功率电子设备，可通过调节金刚石含量匹配器件材料的热 膨胀系数。 市场上多家公司正在开发和推广新型散热材料，如某公司推出的金刚石 与碳化硅陶瓷复合材料，导热率超过 800 W/m·K，是铜的两倍，且与 硅的热膨胀特性相匹配。 Q&A 金刚石在芯片散热领域的应用前景如何？ 金刚石作为一种高效散热材 ...

Market Overview - A total of 48 stocks hit the daily limit up, while 25 stocks faced limit down, resulting in a sealing rate of 66% [1] - The market experienced fluctuations throughout the day, with the ChiNext index dropping over 1% after initially rising more than 1% in the morning [1] - The total trading volume in the Shanghai and Shenzhen markets reached 1.67 trillion yuan, an increase of 76.5 billion yuan compared to the previous trading day [1] - Over 3,800 stocks in the market declined, with the Shanghai Composite Index down 0.51%, the Shenzhen Component Index down 0.78%, and the ChiNext Index down 1.12% [1] Stock Performance Analysis - The consecutive limit-up rate for stocks decreased to 37.5%, with significant movements in high-priced stocks causing internal divergences among speculative stocks [3] - Stocks such as Hai Xin Food and Hai Wang Bio achieved six consecutive limit-ups, while Dao Ming Optical reached five consecutive limit-ups [1][9] - The commercial aerospace sector saw mixed performance, with only Shun Hao Co. achieving a four-day consecutive limit-up, while other high-priced stocks faced declines [5] Sector Highlights - The superhard materials sector saw a surge, with stocks like Huanghe Xuanfeng and Sifangda rising over 10% due to increased demand driven by AI developments [6] - The coal sector benefited from rising coal prices, with stocks like Antai Group and Xinda A achieving consecutive limit-ups [27] - The wind power sector is expected to maintain high growth, supported by new policies and upcoming events [29] Consumer Sector Insights - The consumer sector remained active, driven by policies supporting Taiwanese businesses in Fujian, with stocks like Hai Xin Food and An Ji Food achieving consecutive limit-ups [6][17] - The recent surge in consumer spending is attributed to event-driven factors, indicating a correlation with market sentiment [6] Future Market Outlook - The three major indices showed a pattern of rising and falling, with a slight increase in trading volume, indicating potential adjustments driven by large-cap funds [7] - The market may be nearing a bottom, with indicators suggesting a possible rebound if the indices can recover short-term moving averages [7]

Market Overview - The market experienced fluctuations with the ChiNext Index dropping over 1%, despite an early gain of more than 1%. The total trading volume in the Shanghai and Shenzhen markets reached 1.67 trillion, an increase of 76.5 billion compared to the previous trading day. Over 3,800 stocks declined across the market [1]. Sector Performance - The coal sector showed resilience, with stocks like AnTai Group and DaYou Energy hitting the daily limit. The price of coal has risen unexpectedly since the fourth quarter, with October's thermal power generation increasing by 7.3% year-on-year. Seasonal demand is expected to rise further from late November, leading to a stable to strong coal price outlook for the end of the year and into 2026 [2]. - The superhard materials and cultivated diamonds sectors also performed well, with Huanghe Xuanfeng hitting the daily limit. The diamond industry is gaining attention due to the high heat dissipation demand from AI development, potentially transforming diamonds from optional to essential materials. The compound annual growth rate for this application could exceed 40-50% [3][4]. Individual Stock Highlights - In the commercial aerospace sector, stocks like Shunhao Co. and Aerospace Machinery experienced significant gains, with Shunhao Co. achieving a four-day limit increase. The successful launch of the Zhuque-3 rocket on December 3 has contributed to this sector's volatility and potential for future growth [3][4]. - High-profile stocks faced significant selling pressure, with some experiencing sharp declines. However, certain stocks like HaiXin Food and DaoMing Optics managed to rise against the trend, indicating selective investor interest despite overall market weakness [6][8]. Future Market Analysis - The market continues to adjust, with all three major indices breaking below their five-day moving averages. The increase in trading volume suggests a potential for further short-term declines. However, sectors like commercial aerospace and AI-related technologies still show promise for recovery, making them focal points for investors [8].

Core Viewpoint - The superhard materials sector is experiencing significant movement, driven by the increasing demand for diamonds in both consumer and industrial applications, particularly due to advancements in artificial intelligence and cooling requirements [2] Group 1: Company Overview - As of December 3, there are 865 existing companies related to cultivated diamonds in China, with over 60% of these companies established for more than 10 years [3] - The diamond industry is shifting from being an optional material to a necessary one due to high thermal conductivity demands driven by AI development [2] Group 2: Regional Distribution - The majority of cultivated diamond companies are concentrated in the Central China region, which accounts for 34.1% of the total, followed by East China at 29.5%, while the Northwest region has the least representation at 1.3% [4] Group 3: Capital Structure - The cultivated diamond sector is primarily composed of small and micro enterprises, with a low capital threshold; 52.6% of companies have registered capital of less than 2 million yuan, and 30.9% have capital of less than 1 million yuan [5]
