Abstract
A method of picking up an electric device which is detachably connected by its underside on a mount, by means of a holding tool. First, a second mount is detachably fastened on the upper side of the electric device such that the holding force between the electric device and the second mount is greater than the holding force between the first mount and the electric device. Next, the first mount is separated from the electric device. Finally, the electric device is picked up, on its underside, from the second mount by the holding tool.
Claims12
A method for picking up an electric device having an upper side and an underside, the electric device being detachably fastened, by its underside, on a first mount, the method comprising steps of:
- a) dividing a semiconductor wafer into individual chips, a single chip being used as the electric device;
- b) detachably fastening a second mount on the upper side of the electric device such that a holding force between the second mount and the electric device is greater than a holding force between the first mount and the electric device;
- c) separating the first mount from the electric device;
- and
- d) picking up the electric device, by its underside, from the second mount by means of a holding tool, the upper side of the electric device attachable to a substrate when the electric device is separated from the second mount.
