    • A method of producing a multilayer interconnection board is disclosed that includes the steps of processing a resin member on an interconnection layer by imprinting press, and removing residue of the resin member at the bottom of a via hole after forming the via hole. In the method of producing a multilayer interconnection board, a thermal setting resin, which has a setting temperature higher than that of the resin member, is applied on a via-connecting portion of the interconnection layer, the resin member is formed on the interconnection layer, an interconnection groove and a via hole are formed by imprinting press on the resin member by using a tool, and an un-cured portion of the high temperature setting resin is dissolved and removed by using a resin solvent. Thereby, residue of the resin member on the thermal setting resin is removed.
    • 公开了一种制造多层互连板的方法,其包括通过压印机在互连层上处理树脂部件的步骤,以及在形成通孔之后在通孔的底部除去树脂部件的残留物。 在制造多层互连板的方法中,将具有比树脂构件的设定温度高的设定温度的热定型树脂施加在互连层的过孔连接部分上,树脂构件形成在互连层 通过使用工具通过压印在树脂部件上形成互连槽和通孔,并且通过使用树脂溶剂将高温固化树脂的未固化部分溶解并除去。 由此,除去热固化树脂上的树脂部件的残留物。
