Electrical uniformity analyses on 12-inch Si-based Hf0.5Zr0.5O2 ferroelectric capacitor devices by atomic layer deposition

引用

Progress in Natural Science:Materials International 2024年第3期34卷 598-605页

作者： Wen-Juan Ding Yu liu Zhi-Qiang Xiao li Gao Yu-Chen li lin Zhu Xiang li wei-min li Shuang Chen Ai-Dong li National Laboratory of Solid State Microstructures College of Engineering and Applied Sciences and Collaborative Innovation Center of Advanced MicrostructuresNanjing University Jiangsu Leadmicro Nano-Technology Co. Ltd. Semiconductor Manufacturing North China Corp. Kuang Yaming Honors School Nanjing University

The study on the uniformity of electrical performance of large wafer-scale Hf0.5Zr0.5O2（HZO） ferroelectric capacitors is still lacking yet now. In this work, TiN/HZO/TiN metal-ferroelectric-metal（MFM） devices on 12-inch silicon wafers have been fabricated by thermal atomic layer deposition. The correlation of thickness uniformity with device-to-device variation of electrical properties and yield of the 12-inch MFM system was investigated. It was found that the uniformity of ferroelectric properties is closely related to the variation of HZO thickness of the MFM system, the concentration of oxygen vacancies in the micro-region of the HZO film, and the ferroelectric phase micro-distribution on 12-inch Si wafer. This work provides some important information for the performance optimization of HfO2-based ferroelectric random access memories.

随着我国集约化家禽养殖业的迅速发展,家禽饲料原料的需求量迅速增加。但谷物饲料的短缺及持续居高的价格使家禽饲料生产行业亟须探寻更为廉价的能量替代饲料。木薯具有产量高、富含淀粉和纤维、能值较高等特点,在家禽养殖中可替代玉米或其他能量饲料。木薯产品的有效利用已被证明可降低家禽生产中的饲料成本。但木薯的利用受许多因素的限制,如低蛋白质以及抗营养因子,使用正确的加工及科学的配方可以提高木薯在家禽饲粮中的添加水平。文章综述木薯的营养特性、饲料化利用方式及在家禽饲粮中的应用研究,为木薯在家禽饲粮中的应用提供参考。
