Sintering die attach; IC encapsulation Baking; Plating; Lasermarking; Trim and form; Wafer bonding; Sintering die attach is a process that involves placing the semiconductor die onto the substrate and then subjecting it to high temperature and pressure in a controlled environment. [18]
A die, in the context of integrated circuits, is a small block of semiconducting material on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs ) through processes such as photolithography .
Wafer mounting is a step that is performed during the die preparation of a wafer as part of the process of semiconductor fabrication. During this step, the wafer is mounted on a plastic tape that is attached to a ring. Wafer mounting is performed right before the wafer is cut into separate dies. The adhesive film upon which the wafer is mounted ...

To attach the flip chip into a circuit, the chip is inverted to bring the solder dots down onto connectors or pads on the underlying electronics or circuit board or substrate. The solder is then re-melted to produce an electrical connection, typically using a thermosonic bonding or alternatively reflow solder process. [7]
The die is glued or soldered to the die pad inside the lead frame, and then bond wires are attached between the die and the bond pads to connect the die to the leads in a process called wire bonding. In a process called encapsulation, a plastic case is moulded around the lead frame and die, exposing only the leads.
Tape-automated bonding (TAB) is a process that places bare semiconductor chips (dies) like integrated circuits onto a flexible circuit board (FPC) by attaching them to fine conductors in a polyamide or polyimide (like trade names Kapton or UPILEX) film carrier. This FPC with the die(s) (TAB inner lead bonding, ILB) can be mounted on the system ...
Die singulation, also called wafer dicing, is the process in semiconductor device fabrication by which dies are separated from a finished wafer of semiconductor. [1] It can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw ) [ 2 ] or laser cutting .
