Abstract
A tape carrier for semiconductor apparatus and a method of manufacturing the tape carrier includes three or more layers and contact holes of small size. A peelable agent is applied to a planar substrate made of glass or the like, and plural insulating layers and plural conductive layers are alternatingly formed thereon in predetermined patterns. The peelable agent is then removed to peel the tape carrier from the substrate. The tape carrier includes the insulating layers and the conductive layers and has projection electrodes but no tape base.
