ZJ-3型压电测试仪(静压电系数d33测量仪)是为测量压电材料的d33常数而设计的专用仪器,它可用来测量具有大压电常数的压电陶瓷,小压电常数的压电单晶及压电高分子材料。此外,也可测量任意取向压电单晶以及某些压电器件的等效压电d’33常数,仪器测量范围宽,分辨率细,可靠性高,操作简单,对试样大小及形状无特殊要求,圆片...
(g.) DRIE刻蚀SOI顶硅,完成结构层的图形化。(h.) 最后,DRIE刻蚀SOI背硅,完成悬空结构的释放。 图5-1 AlN-顶硅掺杂工艺流程 从工艺流程来看,该工艺并不算复杂,属于典型的生长一层刻蚀一层的工艺流程。这种工艺流程的缺点在于,各层都有厚度限制。因为是生长一层刻蚀一层,所以下一层生长的时候,会遇到上一层...
