Abstract
A manufacturing apparatus of a semiconductor device includes: multiple processing heads provided apart from each other in order to perform predetermined processing in different positions on a common lead frame, the processing heads respectively including cameras; and a controller controlling driving of the processing heads, the controller positioning each of the processing heads at a position where at least an optical offset is canceled out. The controller takes an image of a paste of one island by the cameras and acquires optical inspection images respectively corresponding to the processing heads before the positioning, and calculates, as the optical offset, an amount of difference between the processing heads in a relative positional relationship between the island and the paste shown in the optical inspection images.
