CERAMIC CIRCUIT BOARD AND MANUFACTURING METHOD FOR THE SAME

摘要

A manufacturing method of a ceramic laminated substrate and a ceramic laminated substrate manufactured by the same are provided to prevent deformation of a cavity in a firing process by constraining the cavity by filler. A cavity(3) is formed in a sheet(2). The sheet is laminated on a ceramic laminate(10). A filler(20) is filled in the cavity by a screen printing. The filler is dried. A constraining material(11) is laminated on the sheet and the ceramic laminate. The sheet and the ceramic laminated are sintered. The filler and the constraining material are removed from the ceramic laminate after sintering. The filler has a sintering temperature more than the constraining material. The filler includes alumina slurry.
