摘要: 一种导电互连(340、440、540、640)包括导电支承层(330、430、530、630),在该导电支承层(330、430、530、630)上的导电材料(320、520、620),以及部分地包围该导电材料(320、520、620)的无机套环(350、450、550、650)。无机套环(350、450、550、650)也被布置在导电支承层(330、430、530、630)的侧壁上。一种制造导电互连(340、440、540、640)的方法包括在籽晶层(304、504)上制造导电材料(320、520、620),形成有机套环(310、510)以部分地包围该导电材料(320、520、620),蚀刻导电籽晶层(304、504)以形成导电支承层(330、430、530、630),以及进行加热以将有机套环(310、510)转变为无机套环(350、450、550、650),该无机套环(350、450、550、650)部分地包围导电材料(320、520、620)并布置在导电支承层(330、430、530、630)的侧壁上。有机套环(310、510)可通过在导电材料(320、520、620)上沉积光敏旋涂电介质材料并图案化该光敏旋涂电介质材料来形成。导电材料(620)可以是单个导电材料(320)或者可包括由势垒层分隔的第一导电层(332)和第二导电层(324)的堆叠,在这种情况下加热步骤还导致导电材料堆叠中的第二导电层(324)的回流。
