Tun-Chih Shih has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11784158
    Abstract: A producing apparatus and a pre-bonding device are provided. The pre-bonding device includes a dispensing mechanism and a die-placing mechanism that is arranged adjacent to the dispensing mechanism. The dispensing mechanism is configured to form a plurality of adhesives onto a plurality of carriers, respectively. The die-placing mechanism includes a plurality of catchers configured to respectively hold a plurality of chips and a correction unit that is configured to adjust a relative position of the chips. The catchers are configured to synchronously place the chips adjusted by the correction unit onto the adhesives, respectively.
    Type: Grant

  • Patent number: 10643968
    Abstract: A vertically die-stacked bonder able to stack laterally dies one by one includes a self-elevating unit, a retrieval unit neighbored to the self-elevating unit, and a receiving unit neighbored to the retrieval unit. At least one die is located at the self-elevating unit. The self-elevating unit elevates one die by 90 degrees, so as to form a vertical state. The retrieval unit hands over the die in the vertical state to the receiving unit. The self-elevating unit then elevates another die by 90 degrees once again. The retrieval unit stacks laterally the another die in the vertical state to the previous die at the receiving unit. Thereupon, by stacking laterally the dies in the vertical state orderly, the speed of die stacking can be increased, the production costs can be reduced, and the productivity can be increased.

  • Patent number: 6132161
    Abstract: A chip supplying apparatus for picking chips from a wafer positioned on an elastic film is disclosed. The chip supplying apparatus includes a shifting device, a clutch device, a film-expanding device, and a chip-picking device. In the present chip supplying apparatus, the input torque provided by the clutching device for driving the film-expanding device to perform a film-expanding operation is orthogonal to the resulting rotation torque of the film-expanding device. Therefore, when the film-expanding operation is performed, the film-expanding device will not shake. In other words, the present chip supplying apparatus can perform stable film-expanding operation.
