  • Publication number: 20230402308
    Abstract: Aspects of the present disclosure relate to a transfer device, system, and method for transferring an electronic component onto a placement position on a substrate. The transfer device is based on a fluidic process principle in which electronic components are transferred in a transfer liquid. In accordance with an aspect of the present disclosure, the transfer device further includes a plurality of acoustic transducers, and a controller for controlling the plurality of acoustic transducers. The controller is configured to control the plurality of acoustic transducers to create an acoustic trap in the transfer liquid for capturing an electronic component when it is released in the transfer liquid and to subsequently manipulate the position and/orientation of the acoustic trap for the purpose of positioning the electronic component at the placement position on the substrate.

  • Publication number: 20230260954
    Abstract: The disclosure relates to an apparatus for transferring a semiconductor die from an arrangement of semiconductor dies to a target and to a wafer stage to be used in such an apparatus. The wafer chuck includes a rotationally mounted curved shell on which the arrangement of semiconductor dies can be arranged, and the wafer stage includes a first motor for rotating the curved shell around a rotational axis. The curved configuration allows an improved throughput of the wafer stage. The film frame carrier used with this wafer stage comprises a ring-shaped body with an asymmetric bending stiffness allowing the ring-shaped body to be bent so that the mounting surface of the ring-shaped body changes from having a first shape to a second more concave shape and prevents or limits the ring-shaped body to be bent so that the shape of the mounting surface becomes more convex than the first shape.

  • Publication number: 20230230892
    Abstract: A semiconductor device such as a chip-scale package is provided. Aspects of the present disclosure further relate to a method for manufacturing such a device. According to an aspect of the present disclosure, a semiconductor device is provided that includes a conformal coating arranged on its sidewalls and on the perimeter part of the semiconductor die of the semiconductor device. To prevent the conformal coating from covering unwanted areas, such as electrical terminals, a sacrificial layer is arranged prior to arranging the conformal coating. By removing the sacrificial layer, the conformal coating can be removed locally. The conformal coating covers the perimeter part of the semiconductor die by the semiconductor device, in which part a remainder of a sawing line or dicing street is provided.

  • Publication number: 20220020679
    Abstract: A semiconductor device is provided that includes a substrate, a pocket within the substrate, a solderable/glueable re-distribution layer arranged in the pocket and a die. The die is arranged downwards, so that a base contact and an emitter contact of the die face the bottom of the device, and a collector contact of the die faces the top of the device. The solderable/glueable re-distribution layer includes a first and second re-distribution layer part and the first re-distribution layer part and the second re-distribution layer part are isolated from each other by an isolating material. The emitter contact is connected to the first re-distribution layer part and the base contact is connected to the second re-distribution layer part. The emitter contacts via the first re-distribution layer part, the base contacts via the second re-distribution layer part, and the collector contact are fan out to the top surface of the semiconductor device.

  • Patent number: 7726011
    Abstract: In a chip transferring apparatus a wafer (44) and a lead frame (50) are positioned. A first chip (42) is picked up from the wafer (44) by a transfer head (14; 40a-40d) in a chip pick-up position, while bonding a second chip to the lead frame (50) by another transfer head in a chip bonding position. The first chip (42) is then transferred by said one of the transfer heads from the chip pick-up position to the chip bonding position. Next, the first chip (42) is bonded on the lead frame (50) by said one of the transfer heads (14; 40a-40d) in the chip bonding position, while another one of the transfer heads picks up a third chip from the wafer (44) in the chip pick-up position. Each transfer head (14; 40a-40d) comprises a collet (66a-66d) which, through a mechanical coupling, is coupled to another collet for compensating radial forces exerted on the collet relative to said axis of rotation.

  • Patent number: 7677523
    Abstract: A gravity compensation device partially or completely compensates a force exerted by a basic mass (10) on a balancing device (12) at a first distance from an axis of rotation (13) by using a force generating device, such as spring (14), exerting a counterforce on the balancing device at a second distance from the axis of rotation. The first distance, the second distance, or both are selectable for providing the desired gravity compensation. One or more pulleys with an angle-variable radius may be used. The gravity compensation device does not add substantial mass to the basic mass, and is simple in design.
