晶圆制造 薄膜沉积
2023/12/3
2023年10月20日，上海微系统所魏星研究员团队在300 mm SOI晶圆制造技术方面取得突破性进展，制备出了国内第一片300 mm 射频（RF）SOI晶圆。团队基于集成电路材料全国重点实验室300 mm SOI研发平台，依次解决了300 mm RF-SOI晶圆所需的低氧高阻晶体制备、低应力高电阻率多晶硅薄膜沉积、非接触式平坦化等诸多核心技术难题，实现了国内300mm SOI制造技术从无到有的重...
针对抗肿瘤小分子药物靶向性差、疗效低和毒副性大等缺陷，我们以Y型分子筛（YMS）为基体、阿霉素（DOX）为药物模型，通过pH调控，借助氢键和范德华力等物理作用力制备得到高负载Y型分子筛纳米药物体系（YMS-DOX）。采用UV-Vis、FT-IR、粒径和电位测试及荧光光谱证实YMS-DOX成功制备，且DOX的负载率可高达99.61%。体外药物释放测试发现YMS-DOX具有pH响应释放特性，在肿瘤环境...
