Abstract:
A method of manufacturing a lead frame for use in manufacturing a semiconductor device including a semiconductor chip, comprising:a first step of forming an outer frame, supporting leads connected with said outer frame and inside inner leads whose tips are connected with said supporting leads by selectively removing a metal plate for said lead frame;a second step of fixing an insulator on top faces of said supporting leads and said inside inner leads; anda third step of removing at least a connecting portion between said inside inner leads and said supporting leads by selectively removing said metal plate with said inside inner leads supported by said supporting leads through said insulator,wherein said inside inner leads are made to be separated from one another with tips thereof disposed within or in the vicinity of an area for said semiconductor chip and with ends thereof disposed at outside of said area for said semiconductor chip and separated from said outer frame.
