Abstract

A semiconductor manufacturing apparatus and a method of manufacturing a semiconductor device are provided. A horizontal driver ( ) and a vertical driver ( ) are controlled to move a punch holder ( ), or an end portion ( T ) of a punch ( ), within a plane defined by first and second directions (D , D ). A tip ( A) of the punch ( ) is brought into contact with leads ( ), with a punch-side forming surface ( S) and a die-side forming surface ( S) maintained in parallel relationship. A pressurizer ( ) is controlled to move the end portion ( T ) in a fourth direction (D ) toward the die-side forming surface ( S), and the punch-side forming surface ( S) and the die-side forming surface ( S) hold the leads ( ) therebetween. A pressure detector ( ) detects a load placed upon the punch ( ). A controller ( ) receives a detection signal (S ) from the pressure detector ( ) and controls the pressurizer ( ) to place a predetermined load upon the lead ( ) held between the punch-side forming surface ( S) and the die-side forming surface ( S). The semiconductor manufacturing apparatus is capable of accurately forming the leads of the semiconductor device without damages to the leads.
