摘要:
The present disclosure is directed to an apparatus for the application of soldering flux to a semiconductor workpiece. In some embodiments the apparatus comprises a dipping plate having a reservoir which is adapted to containing different depths of flux material. In some embodiments, the reservoir comprises at least two landing regions having sidewalls which form first and second dipping zones. The disclosed apparatus can allow dipping of the semiconductor workpiece in different depths of soldering flux without the necessity for changing dipping plates.

摘要:
A method includes generating a solvent-containing vapor that contains a solvent. The solvent-containing vapor is conducted to a package assembly to clean the package assembly. The solvent-containing vapor condenses to form a liquid on a surface of the package assembly, and flows off from the surface of the package assembly.

The present disclosure is directed to an apparatus for the singulation of a semiconductor substrate or wafer. In some embodiments the singulation apparatus comprises a plurality of cutting devices. The cutting devices are configured to form multiple concurrent cutting lines in parallel on a surface of the semiconductor wafer. In some embodiments, the singulation apparatus comprises at least two dicing saws or laser modules. The disclosed singulation apparatus can dice the semiconductor wafer into individual chips by dicing in a direction across a complete circumferential edge of the wafer, thereby decreasing process time and increasing throughput.

摘要:
A method includes reflowing a solder region of a package structure, and performing a cleaning on the package structure at a cleaning temperature higher than a room temperature. Between the step of reflowing and the step of cleaning, the package structure is not cooled to temperatures close to the room temperature.

摘要:
A method of bonding includes providing a first work piece, and attaching a second work piece on the first work piece, with a solder bump disposed between the first and the second work pieces. The second work piece is heated using a heating head of a heating tool to melt the solder bump. After the step of heating the second work piece, one of the first and the second work pieces is allowed to move freely in a horizontal direction to self-align the first and the second work pieces. After the step of allowing one of the first and the second work pieces to move, a temperature of the heating head is lowed until the first solder bump solidifies to form a second solder bump.
