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.

A flux dipping apparatus includes a flux plate having a top surface; and a dipping cavity in the flux plate and recessed from the top surface. A flux leveler is disposed over the flux plate and configured to move parallel to the top surface. A piezoelectric actuator is configured to adjust a distance between the flux leveler and the top surface in response to a controlling voltage applied to electrodes of the first piezoelectric actuator.
