2025年8月28日，上海市浦东新区人民法院的一纸裁定，为曾经风光无限的上海梧升半导体集团有限公司画上了句号。这家注册资本高达100亿元的半导体 企业，最终以归集财产1100元、负债590余万元的尴尬局面，草草终结了破产清算程序。从2021年高调宣布投资不低于180亿元打造半导体全产业链，到 2025年资产不足以支付破产费用，仅仅过去了四年。 梧升半导体成立于2021年3月，正值国内半导体投资热潮之际。在成立初期，公司及其母公司梧升电子科技集团曾备受瞩目，在2021年上海全球投资促进 大会上高调宣布，梧升半导体项目将落户上海浦东，计划总投资额不低于180亿元，并雄心勃勃地提出要在五年内完成晶圆制造、封装测试及研发设计等 全产业链建设。 事实上，梧升半导体及其关联公司从成立起就显露出明显的资金不足问题。以南京梧升半导体项目为例，虽然注册资本一度增至32.85亿元，但最终因资 金不到位而被迫终止，南京经开区工作人员证实："梧升后续没有到资，包括人员配置都没有到，在多次沟通后我们就发函给了梧升，要求终止合同"。 梧升半导体的管理层问题是导致公司迅速衰败的关键因素之一。公司法定代表人及实际控制人张嘉梁的背景与半导体行 ...

台积电2nm产线将全面排除中国设备的消息引发市场担忧，不止大陆半导体设备遭受冲击，台湾半导体业界亦风声鹤唳。 据悉，台积电2nm已逐步替换 中微公司和屹唐股份美国子公司Mattson Technology的设备，这些企业曾参与其先进制程生产。 最近据Digitimes报道，台积电将再次对其供应链进行提前审查，这次的目标涵盖"大联盟"与"小联盟"成员，其中包括众多台湾本地设备与材料供应商。 需要指出的是，随着中国大陆加速半导体自主化，我国台湾厂商在台积电之外获得了大量订单。无论是直接合作、通过本地合作伙伴，还是在中国大陆设 厂，与中国大陆客户合作变得愈加有吸引力，因为来自中国大陆晶圆厂和封测厂的订单往往毛利更高、规模更大。业内人士指出，台积电不仅在排除大陆 供应商、审查台湾厂商的中国大陆营收，还在增加对美欧日设备与材料的依赖。然而，由于台湾厂商本身占比相对较小（主要集中于后段设备），转单至 国外的实际好处有限。 部分供应商进一步指出，台积电订单利润较低，且往往要求提供两年的免费试用。因此，一些企业不愿意为争取台积电订单而亏损。 虽然成为台积电供 应商能提升企业形象、技术认可度与市场声誉，但实际财务收益有限。在必 ...
