  • Patent number: 11946529
    Abstract: A sliding table assembly includes a sliding seat unit slidably mounted to a base unit. Two auxiliary sliding seats are slidably mounted to the base unit and disposed on two sides of the sliding seat unit. A connection member is connected between the auxiliary sliding seats. Two roller sets are respectively mounted to the auxiliary sliding seats. Each roller set has rollers to roll on the base unit. A driving screw rod is coupled to the sliding seat unit and embraced by the auxiliary seats. When the sliding unit is moved by the driving screw rod, it pushes the auxiliary sliding seats to slide together therewith.

  • Patent number: 11658046
    Abstract: Batch semiconductor packaging structures with back-deposited shielding layer and manufacturing method are provided. A grid having multiple frames is glued on an adhesive substrate. Multiple semiconductor devices respectively align with corresponding frames and are stuck on the adhesive substrate. Then a metal layer covers the semiconductor devices and the grid. A distance between four peripheries of a bottom of each semiconductor device and the corresponding frame is smaller than a distance between the bottom and the adhesive substrate, so that the a portion of the metal layer extended to the peripheries of the bottom is effectively reduced during forming the metal layer. After the semiconductor devices are picked up, no metal scrap is remined thereon. Therefore, the adhesive substrate does not need to form openings in advance and is reusable. The grid is also reusable so the manufacturing cost of the present invention is decreased.

  • Publication number: 20220118631
    Abstract: A head of chip picker is disclosed. The head has a clipping seat and an elastic block. The clipping seat has a body and two arms. The arms are respectively and downwardly extended from two opposite sides of an inner top surface of the body, so a cavity with a wide-top and narrow-bottom shape is constituted among the inner top surface and the arms. The elastic block matches the cavity and is laterally inserted into the cavity. The elastic block is not deformed after inserting into the cavity and provides a flat bottom surface.

  • Publication number: 20210339338
    Abstract: A laser cutting method for a wafer is provided. First, an active side of a wafer is cut by a laser to form multiple cutting grooves so that the thicker and harder layer of the integrated circuit on the active side is cut. Then the stealth laser is used to cut the backside of the wafer by aligning the beams of the stealth laser with the cutting grooves. Therefore, the cutting grooves easily extend to the backside of the wafer and penetrate through the wafer to dice the wafer into multiple independent chips.

  • Publication number: 20190275600
    Abstract: A flux transfer tool includes a flux tray, a baseplate, a flux transfer head and a flexible member. The baseplate is disposed on the flux tray. The baseplate has a plurality of holes formed thereon. The flux transfer head is arranged corresponding to the flux tray and configured to move with respect to the flux tray. The flexible member is disposed on the flux transfer head. The flexible member faces the baseplate when the flux transfer head is located above the flux tray. When the holes are filled with a flux, the flux transfer head moves towards the flux tray, such that the flexible member adsorbs the flux from the holes.

  • Patent number: 10388535
    Abstract: A wafer processing method uses a chuck table with smaller diameter than a semiconductor wafer to be processed. A cut through edge trimming is therefore implemented on the periphery of the semiconductor wafer to form a cut through straight side at the periphery and also form a flat portion at the periphery as a positioning means for taping and backside grind processes.

  • Publication number: 20190247944
    Abstract: A flux transfer tool includes a frame, a plunger, a baseplate, a flux supplier and a driving mechanism. The frame has a chamber. The plunger is movably disposed in the chamber. The baseplate is mounted on the frame. The baseplate has a plurality of holes formed thereon. The flux supplier is connected to the frame and contains a flux. The flux supplier supplies the flux to the chamber between the plunger and the baseplate. The driving mechanism is disposed on the frame. The driving mechanism drives the plunger to move towards the baseplate to squeeze the flux out of the holes of the baseplate. The driving mechanism drives the plunger to move away from the baseplate to keep the flux in the chamber.
