三星优化产线布局,年内关闭一座8英寸晶圆代工厂
Huan Qiu Wang Zi Xun· 2026-01-15 07:19
Core Viewpoint - Samsung Electronics is accelerating the restructuring of its foundry production lines by planning to close its 8-inch wafer foundry S7 in the Giheung area of South Korea within 2024, focusing resources on more profitable 12-inch production lines to enhance overall business competitiveness [1]. Group 1: Company Actions - Samsung currently operates three 8-inch wafer fabs in the Giheung area, with S6 and S8 remaining operational after the closure of S7 [2]. - Following this adjustment, Samsung's monthly production capacity for 8-inch wafers will decrease from 250,000 to below 200,000 wafers [2]. - The decision to close the S7 plant is driven by the overall operating rate of Samsung's 8-inch wafer fabs being around 70%, and the migration of core products like CMOS image sensors and display driver chips to 12-inch lines, leading to increased operational cost pressures [2]. Group 2: Industry Trends - The global capacity for 8-inch wafers is expected to decline by 2.4% year-on-year in 2024, with TSMC also reducing its related capacity since 2023, indicating a trend of capacity optimization within the industry [2]. - Despite the reduction in capacity, market demand remains strong, particularly due to the rapid growth of the AI server industry, which is driving high demand for power management chips [3]. - TrendForce predicts that the average operating rate of global 8-inch wafer fabs will rise to between 85% and 90% in 2024, prompting some foundries to plan price increases ranging from 5% to 20% [3]. - DB Hitek, a local foundry in South Korea, is expected to benefit from this capacity contraction, as its production capacity is fully utilized and it currently cannot accept new orders due to significant order backlogs [3].

苹果发布多模态AI模型Manzano,实现“看图”与“绘图”高效融合
Huan Qiu Wang Zi Xun· 2026-01-15 07:19
【环球网科技综合报道】1月15日消息,据AIBase报道,苹果公司近日发表重磅研究论文,正式推出名 为"Manzano"的多模态人工智能模型。该模型创新性地实现了"视觉理解"与"文本生成图像"两大核心功 能的接近无损融合,为多模态AI技术发展注入新动力。 在AI领域,兼顾图像理解与图像生成两大任务长期面临技术瓶颈。图像理解需依赖连续数据流,而图 像生成则更需要离散数据块,传统模型因采用单一处理架构,往往难以平衡两项任务的性能,存在"看 得懂画不出"或"画得好理解偏"的问题。 来源:环球网 Manzano模型通过创新的三段式架构成功破解这一难题。首先由"混合视觉分词器"同步生成连续与离散 两种视觉表示,既满足图像理解的需求,又为图像生成奠定基础;随后借助大语言模型(LLM)精准 预测图像语义内容,确保对指令的准确把握;最后由"扩散解码器"完成像素级渲染,保障生成图像的高 质量。这一架构设计让模型在保留强大视觉理解能力的同时,具备了精细的图像生成能力,还能胜任深 度估计、风格迁移、图像修复等复杂任务。 测试数据显示,在处理"一只鸟在大象下方飞翔"这类反直觉、违背物理常识的复杂指令时,Manzano的 逻辑准确性与 ...
