摘要:
Methods of fabricating a semiconductor device include forming a deposited film on a semiconductor substrate in a process chamber by repeatedly forming unit layers on the semiconductor substrate. The unit layer is formed by forming a preliminary unit layer on the semiconductor substrate by supplying a process material including a precursor material and film-control material into the process chamber, purging the process chamber, forming a unit layer from the preliminary unit layer, and again purging the process chamber. The precursor material includes a central atom and a ligand bonded to the central atom, and the film-control material includes a hydride of the ligand.

Provided is a method of forming a metal thin film which can reduce leakage current while improving electric properties by improving step coverage of a device. The method of forming a metal thin film includes supplying a metal precursor including chlorine, purging byproducts produced after the supplying of the metal precursor by injecting a purge gas, supplying a reactant to allow the reactant and the metal precursor to react with each other to form a thin film layer, and purging the byproducts produced after the reaction by injecting a purge gas, wherein before the supplying of the metal precursor, the method further includes supplying a reactant to be adsorbed on a treated product.

A method of fabricating and mounting a flip chip includes using an environmentally friendly plasma gas, which minimizes safety hazards during an implementation of the method and does not require an additional heat source during a reflow process thereof. That is, the method includes reflowing a solder bump using an argon-hydrogen plasma process. The argon-hydrogen plasma process used to fabricate the flip chip includes maintaining a pressure in a chamber at 250 to 270 mtorr, feeding a mixed gas of argon with 10 to 20% hydrogen to the chamber to generate a plasma with power of 100 to 200 W, and exposing the flip chip to the plasma for 30 to 120 seconds. Additionally, an argon-hydrogen plasma process used to mount the flip chip includes maintaining pressure in a chamber at 100 to 400 mtorr, feeding a mixed gas of argon with 0 to 20% hydrogen to the chamber to generate a plasma with power of 10 to 50 W, and exposing the flip chip to the plasma for 10 to 120 seconds.
