俄罗斯的芯片技术 started from the Soviet era legacy of vacuum tubes and early semiconductors but hit a low after the USSR collapsed in 1991 because lack of funding and Western tech access. During the 1970s-1980s they built 500+ semiconductor plants but after 1991 most shut down. Recent revival began in 2000s with St. Petersburg labs and university partnerships but got a big blow in 2014 when US/EU sanctions cut off access to advanced equipment. Now they focus on designing chips using Chinese/Korean foundries like TSMC and Samsung. Some progress in AI algorithms and encryption chips but still import 95% of components.

为啥是这个答案呢？先说苏联时期研发投入占GDP的5%，1970年代曾有500家半导体厂 but 1991年后只剩100家 because资金断流。2000-2013年投入30亿美元 but 2014年后西方企业撤离，导致进口量减少70%。现在数据是俄罗斯自产芯片不足5% but 设计软件市场年增15%。他们和韩国合作开发3nm芯片 but 代工全靠中国台湾地区台积电，前年出口额才3.2亿美元，比2014年缩水90%。这些 info 来自俄罗斯联邦统计局和SEMI协会报告，证明技术路径确实受限 but 在加密和AI算法有突破。
