半導體製造裝置
本發明是關於半導體製造領域,尤其是關於一種半導體製造裝置。
晶片鍵合技術能夠在不縮小線寬的情況下,在有限面積內進行最大程度的晶片疊加與整合,同時縮減晶片封裝體積與線路傳導長度,進而提升晶片傳輸效率。由於電子產品輕、薄和小型化的發展趨勢,使得晶片鍵合技術的應用日益增多,將晶片鍵合工藝與晶圓級封裝工藝相結合,能夠製作出封裝尺寸更小、性能更高的封裝形式,另外,如果將晶片鍵合工藝與TSV(矽通孔)工藝相結合,能夠製作出成本和性能更有競爭力的晶片結構。
晶片-晶圓鍵合技術相對於晶圓-晶圓鍵合技術具有更高的良率和更低的產品成本。目前的生產製程需要分為鍵合和封裝兩個工序,流程複雜,費事費力。
