              专家£º国产刻蚀机的确水平一流£¬但不要总¡°戴高帽¡± 近来有网络媒体称£¬¡°中微半导体自主研制的5纳米等离子体刻蚀机£¬性能优良£¬将用于全球首条5纳米芯片制程生产线?#20445;?#24182;评论说¡°中国芯片生产技术终于突破?#35775;?#23553;锁£¬第一次占领世界?#32856;?#28857;¡±¡°中国弯道超车¡±等等¡£中微公司的刻蚀机的确水平一流£¬但夸大阐述其战略意义£¬则被相关专家反对¡£刻蚀只是芯片制造多个环节之一¡£刻蚀机也不是对华禁售的设备£¬在这个意义上不算¡°卡脖子¡±¡£

              首先£¬外行容易混淆¡°光刻机¡±和¡°刻蚀机¡±¡£光刻机相当于画匠£¬刻蚀机是雕工¡£前者投影在硅片上一张精细的电路图(就像照相机?#23186;?#21367;感光)£¬后者按这张图去刻线(就像刻印章一样£¬腐蚀和去除不需要的部分)¡£

              光刻机是芯片制造中用到的最金贵的机器£¬要达到5纳米曝光精度难比登天£¬ASML公司一家通吃高端光刻机;而刻蚀机没那么难£¬中微的竞争对手还有应用材料¡¢泛林¡¢东京电子等等£¬国外巨头体量优势明显¡£

              ¡°中微的等离子刻蚀机这几年进步确实不小£¬¡±科技日报记者采访的一位从事离子刻蚀的专家说£¬¡°但现在的刻蚀机精度已远超光刻机的曝光精度;芯片制程上£¬刻蚀精度已不再是最大的难题£¬更难的是保证在大面积晶圆上的刻蚀一致性¡£¡±

              该专家解释说£¬难在如何让电场能量和刻蚀气体都均匀地分布在被刻蚀基体表面上£¬以保证等离子中的有效基元£¬在晶片表面?#25343;?#19968;个位置实现相同的刻蚀效果£¬为此需要综合材料学¡¢流体力学¡¢电磁学和真空等离子体学的知识¡£

              该专家说£º¡°刻蚀机更合理的结构设计和材料选择£¬可保证电场的均匀分布¡£刻蚀气体的馈入方式也是关键之一¡£据我所知£¬中微尹志尧博士的团队在气体喷淋盘上下过不少的功夫¡£另外包括功率电源¡¢真空系?#22330;?#21051;?#27425;?#24230;控制等£¬都影响刻蚀结果¡£¡±

              另外£¬该专家也指出£¬刻蚀机技术类型很多£¬中微和他们的技术原理就有很大区别£¬至于更详细的技术细节£¬是每个厂家的核心机密¡£

              顺便一提£º刻蚀分湿法(古代?#21496;投?#24471;用强酸去刻蚀金属£¬现代工艺用氟化氢刻蚀二氧化硅)和干法(如用真空中的氩等离子体去加工硅片)¡£¡°湿法出现?#26174;¼‚?#19968;般用在?#25237;?#20135;品上¡£干法一般是能量束刻蚀£¬离子束¡¢电子束¡¢激光束等等£¬精度高£¬无污染残留£¬芯片制造用的就是等离子刻蚀¡£?#22791;?#19987;家称¡£

              上述专家称赞说£¬尹博士以及中微的核心技术团队£¬基本都是从国?#25163;?#21517;半导体设备大厂出来?#27169;?#23609;博士原来就在国外获得了诸多的技术成就¡£中微?#27426;?#25552;高改进£¬逐步在芯片刻蚀机领域保持了与国外几乎同步的技术水平¡£

              在IC业界工作多年的电子工程师张光华告诉科技日报记者£º¡°一两年前网上就有中微研制5纳米刻蚀机的报道¡£如果能在台积电应用£¬的确?#24471;?#20013;微达到世界领先水平¡£但说中国芯片¡®弯道超车¡¯就是夸大其词了¡£¡±

              ¡°硅片从设计到制造到封测£¬流程复?#21360;?#21051;蚀是制造环节的工序之一£¬还有造晶棒¡¢切割晶圆¡¢涂膜¡¢光刻¡¢掺?#21360;?#27979;试等等£¬都需要复杂的技术¡£中国在大部分工序?#19979;?#21518;¡£¡±张光华说£¬¡°而且£¬中微只是给台积电这样的制造企业提供设备£¬产?#24403;?#21488;积电差几个数量级¡£¡±

              记者发现£¬2017年开始网络上经常热炒¡°5纳米刻蚀机?#20445;?#32780;中微公司一再抗议媒体给他们¡°戴高帽¡±¡£

              ¡°不要老把产业的发展提高到政治高度£¬更不要让一些新闻人和媒体搞吸引眼球的不?#24403;?#23548;¡£¡±尹志尧2018年表示£¬¡°对我和中微的夸大宣传搞得我们很?#27426;¯¡­¡?#36807;一些时候£¬?#25351;?#22836;换面登出来£¬实在让我们头痛¡£¡±
