中国制造全球首款采用二维材料的 1 纳米 RISC-V 芯片

​中国科学家成功开发出全球首款基于二维材料的1纳米RISC-V微处理器,名为“Wuji”,集成了5,900个晶体管,厚度不到1纳米。 ​这一突破性成果无需依赖先进的极紫外(EUV)光刻技术,为中国在半导体创新领域开辟了新的独立路径。​该结果已被发布在《自然》杂志中。

随着硅基集成电路在微型化方面接近物理极限,全球研究人员开始转向二维材料,如二硫化钼和二硒化钨,以推动芯片性能的提升。​这些材料通常只有一个原子厚,具备出色的物理特性,使下一代电路的进一步缩放和功能提升成为可能。​

此前,维也纳工业大学在2017年开发的最复杂的二维半导体数字电路仅包含115个晶体管。​而复旦大学的研究团队经过五年的努力,成功将集成度提高了50多倍。​他们在30×30的反相器阵列(共900个)中实现了99.77%的高良率,展示了在原子尺度上保持精确性和均匀性的能力,这对于高制造良率至关重要。​

研究团队表示,这项研究证明了二维半导体在高性能集成电路中的巨大潜力,为未来电子设备的开发提供了新的可能性。​

Pinterest (PINS) Stock Sinks As Market Gains

Pinterest (PINS) closed at $71.75 in the latest trading session, marking a -0.18% move from the prior day. This change lagged the S&P 500's daily gain of 0.1%. Meanwhile, the Dow gained 0.9%, and the Nasdaq, a tech-heavy index, lost 0.59%. Heading into today, shares of the digital pinboard and shopping tool company had lost 17.41% over the past month, lagging the Computer and Technology sector's loss of 5.38% and the S&P 500's gain of 0.71% in that time. Investors will be hoping for strength from PINS as it approaches its next earnings release. The company is expected to report EPS of $0.07, up 170% from the prior-year quarter. Our most recent consensus estimate is calling for quarterly revenue of $467.87 million, up 72.05% from the year-ago period.

The Singapore stock market has alternated between positive and negative finishes through the last five trading days since the end of the two-day winning streak in which it had added more than a dozen points or 0.4 percent. The Straits Times Index now sits just above the 3,060-point plateau and it's likely to see a narrow trading range on Monday.
