中文摘要: 利用H离子注入SiC晶体剥离方法制备光波导可以获得接近于单晶的SiC波导层结构。B离子预注入引入的空位缺陷可以促进H复合体的产生,退火过程中B离子的吸附效应有助于H复合体转化为H2微泡,可以有效降低降低H注入剂量和退火剥离温度。本项目主要对B、H离子共注入SiC晶体剥离过程展开研究,利用RBS/Channeling、红外吸收谱、拉曼散射谱等表征技术,分析B离子注入参数对于形成H复合体种类及比例的影响,探讨B离子促进H复合体微泡转化的物理机制,结合晶片键合工艺在SiO2层上制备剥离后的SiC光波导结构,为注入掺杂促进双元素晶体离子束剥离的理论研究提供实验依据。

英文摘要: SiC crystal waveguide fabricated by H ions slicing could keep crystal structure in waveguide region. Pre-implanted B ions created vacancies that promote the H complexes formation and they help the H- transfer from complexes to blistering. B doping could decrease the minimum implantation dose and annealing temperature in H ion slicing. We will investigate the B and H ion co-implantation slicing in SiC crystals. RBS/Channeling, infrared absorption spectroscopy and Raman scattering spectroscopy testing will be applied. We will analyze the relationship between complexes’ categories and ratio of the B implantation parameter. The mechanism of B ions catalyzing H transferring from complexes to blistering will be investigated. We will fabricate ion-sliced SiC waveguide on SiO2 after wafer bonding and slicing process. The result will contribute to the theoretical research on ion slicing promotion in double element crystal by ion doping.
