Abstract:
A method for fabricating a flip-chip semiconductor package comprising processing a semiconductor device, for example a semiconductor chip and processing a device carrier, for example a substrate. The semiconductor device comprises bump structures formed on a surface thereof. The substrate comprises bond pads formed on a surface thereof. The semiconductor chip is heated to a chip process temperature. The chip process temperature melts solder portions on the bump structures. The substrate is heated to a substrate process temperature, wherein said substrate process temperature may be different to the chip process temperature. The semiconductor chip is spatially aligned in relation to the substrate to correspondingly align the bump structures in relation to the bond pads. The semiconductor chip is displaced towards the substrate to abut the bump structures with the bond pads to thereby form bonds there between. A system for performing the above method is also disclosed.
Abstract:
Manufacturing of semiconductor devices is fully automated for cost savings to be achieved in terms of capital and material costs. Semiconductor devices separated from the lead- frames or substrates are typically washed and dried before being transferred to a plate. The semiconductor devices are then subsequently transferred from the plate to a holding tray. However, the large contact surface between the semiconductor devices and the plate results in the semiconductor devices adhering to the surface of the plate when transferring the semiconductor devices to the holding tray. Furthermore, misalignment also tends to occur when the devices are transferred from the plate to the holding tray due to gravitational displacement of the semiconductor devices occurring during the transfer. An embodiment of the invention describes an apparatus and a method for transferring semiconductor devices into component pockets of holding trays.
Abstract:
Semiconductor devices are typically manufactured from strips. The semiconductor devices are then separated from the strips into individual units. The individual units are washed, dried and placed into rows of component pockets located on JEDEC matrix trays (trays). However, tray warping tends to occur at the centre of the trays due to improper securing of the trays thereby resulting in misaligned component pockets. Hence, the individual units are not accurately positioned and secured into the component pockets. Additionally, the size of the individual units further worsens the problem of tray-warping as the individual units are easily displaceable from the component pockets when not properly secured in the component pockets. An embodiment of the invention describes an apparatus and a method for un-warping trays used for containing semiconductor devices.
