Group 4: Future Prospects - Nvidia is expected to begin mass production of its next-generation Blackwell architecture chips in October, which could enhance performance by up to 30 times [9]. - The demand for AI and GPU technology is increasing, with major companies like Meta and xAI placing significant orders for Nvidia's chips [7][9].

再看A股市场，二季度市场呈现反复震荡行情，大盘在3100-3400点箱体反复震荡。"五穷六绝七翻身"即 将集中在下半年行情，七翻身行情有可能出现，从而有效突破3400点箱体，进一步向上拓展空间。周二 科技板块再次大涨，特别是人形机器人芯片、半导体、无人驾驶等科技股行情再次活跃。今年一季度科 技股大涨，二季度出现回落，但科技股代表了经济转型方向，大力发展科技创新是既定国策。一季度机 器人出现大幅上涨，形成很强赚钱效应，二季度创新药接过上涨接力棒，出现集体回升，虽然近期创新 药板块出现获利回吐，但中长期趋势向上。此外，无人驾驶在周二大幅回升，也吸引了资金关注。AI 正改变着各行各业，通过人工智能加消费可以创造更多需求。目前人工智能发展重点关注三个方面：一 是应用广泛，会逐步与各行业结合，提高工作效率，甚至改变商业模式；二是随着应用规模扩大，成本 不断降低；三是我国人工智能应用场景丰富，可能创造巨大需求，这正是提振消费的重要方面。国常会 提出大力促进人工智能加消费，人形机器人是人工智能加消费最好的落地场景。早在去年年底，部分基 金就开始布局人工智能板块，今年受益于人形机器人板块强势表现，取得较好业绩回报，一季度业绩 ...

如果您希望可以时常见面，欢迎标星收藏哦~ IEEE IEDM 会议由 IEEE 电子器件学会主办，是全球规模最大、最具影响力的论坛，旨在展 示晶体管及相关微纳电子器件领域的突破性进展。 在第 70 届 IEEE IEDM 会议上，他们以"塑造未来的半导体技术"分享了芯片的未来技术。我 们摘录如下，以飨读者。 先进的逻辑技术 基于纳米片的晶体管以及由纳米片构建的3D互补场效应晶体管 (CFET) 是延续摩尔定律微缩的关 键，因为现有的FinFET架构正在达到其性能极限。纳米片是一种环栅 (GAA) 晶体管架构，其中 硅堆叠的沟道完全被栅极包围。它们比FinFET具有更好的静电控制、相对较高的驱动电流和可变 的宽度。而CFET是高度集成的3D设计，其中n-FET和p-FET纳米片相互堆叠。这些堆叠器件可以 单片构建（在同一晶圆上），也可以顺序构建（在单独的晶圆上构建，然后进行转移和集成）。 堆叠器件本质上使晶体管密度翻倍，而无需增加器件尺寸，从而实现更强大的功能，并提高功率效 率和性能。在 IEDM 2024 上，多篇论文推动了以下领域的最前沿研究： 一、台积电全新业界领先的 2 纳米 CMOS 逻辑平台 台积电 ...
