Abstract:
A die bonding apparatus which includes a work placing table for placing thereon a semiconductor device package, a solder supplying mechanism for supplying and locating a bonding agent piece on said semiconductor device package, and a bonding head for locating a semiconductor pellet on said bonding agent piece, the die bonding apparatus comprising a pair of gas injecting heads located to be higher than said semiconductor pellet placed on said work placing table, said gas injecting heads being able to be separated from each other and to be abutted against each other so as to form an opening of the size allowing insertion of said solder supplying mechanism or said bonding head, said gas injecting heads having at least two vertically separated arrays of gas nozzles formed at an inner circumferential wall surface of said opening, means for introducing an inert gas into a closed space between said pair of gas injecting heads and said work placing table, a hold-down member for holding down said semiconductor device package on said work placing table, and a shutter mechanism for causing said pair of gas injecting heads to separate from each other and to abut against each other.
