Title: Apparatus for manufacturing a semiconductor device and method of manufacturing a semiconductor device

Description:
FIELD 
     The disclosure relates to an apparatus for manufacturing a semiconductor device and a method of manufacturing a semiconductor device. 
     BACKGROUND 
     Electronic equipments involving semiconductor devices are indispensable from our daily life. With the advancement of electronic technology, electronic equipments become smaller and smaller in size, and thus semiconductor devices inside the electronic equipments are also getting smaller, thinner and lighter. Thus, flip chip packing (FCP) and wafer level packaging (WLP) technology have been gaining in popularity and is widely applied. This technology provides a wafer level manufacturing of the semiconductor devices with high functions and performances while the size of the semiconductor devices is minimized. 
     FCP and WLP technology are widely adopted for assembling and combining a number of semiconductor components to become a semiconductor package as a chip scale package (CSP) so as to minimize the final size of the semiconductor device as well as the electronic equipment. During the operations of assembling the semiconductor package, the semiconductor package is stored and transported from an operation to a subsequent operation by a supporter such as a tray, a boat, a rack or a magazine etc. However, the semiconductor package includes many semiconductor components with complicated structure and involves many complicated manufacturing operations. The semiconductor package is easily damaged during transportation and transition between operations. 
     As a complexity of the manufacturing operations and the configuration of the CSP are increased, there are more challenges to a yield of manufacturing and a simplification of operations. As such, there is a continuous need to improve the method for processing the CSP and solve the above deficiencies.

     DETAILED DESCRIPTION OF THE INVENTION 
     A semiconductor package is manufactured by a number of operations. During the manufacturing of the semiconductor package such as flip chip scale package (FCCSP), a flip chip die is bonded on a wafer substrate held by a boat. A number of solder bumps pads on the wafer substrate are bonded with a number of flip chip solder bumps on a bottom surface of the flip chip die. The flip chip solder bumps are then reflowed by a heat treatment. Underfill and molding compound including an electrically non-conductive material are applied to fill space between the flip chip die and the flip chip solder bumps in order to protect the flip chip solder bumps from cracking. The flip chip die is then individualized from the wafer substrate by singulation. 
     Each of the flip chip die is transferred from the tray to a boat for a subsequent operations of heat sink attachment and ball mounting, and the solder balls have to be heat treated by reflow. The FCCSP is then transferred from the boat back to the tray for packing and dispatching. However, such manufacturing operations involve many transitions of the wafer substrate between different supporters, for example tray to boat or boat to tray. 
     Furthermore, the heat sink has to be attached on the die and the underfill and molding compound have to be used for heat sink attachment even the die is damaged or without die before the operations of heat sink attachment. This leads to materials wastage issue. 
     The manufacturing and use of the embodiments are discussed in details as below. It should be appreciated, however, that the embodiments provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts.
