The invention discloses a method for cleaning residues from a semiconductor substrate during a nickel platinum silicidation process, comprising using an aqua regia cleaning solution (comprising a mixture of nitric acid and hydrochloric acid) with microwave assisted heating. Low boiling temperature of hydrochloric acid prevents heating the aqua regia solution to a high temperature, impeding the effectiveness of post silicidation nickel and platinum residue removal. Therefore, embodiments of the invention provide a microwave assisted heating of the substrate in an aqua regia solution, selectively heating platinum residues without significantly increasing the temperature of the aqua regia solution, rendering platinum residues to be more soluble in aqueous solution and thereby dissolving it from the surface of the substrate.

Embodiments of the current invention include methods of forming a strontium titanate (SrTiO3) film using atomic layer deposition (ALD). More particularly, the method includes forming a plurality of titanium oxide (TiO2) unit films using ALD and forming a plurality of strontium oxide (SrO) unit films using ALD. The combined thickness of the TiO2 and SrO unit films is less than approximately 5 angstroms. The TiO2 and SrO units films are then annealed to form a strontium titanate layer.

Electrical testing of metal oxide semiconductor (MOS) high-k capacitor structures is used to evaluate photoresist strip or cleaning chemicals using a combinatorial workflow. The electrical testing can be able to identify the damages on the high-k dielectrics, permitting a selection of photoresist strip chemicals to optimize the process conditions in the fabrication of semiconductor devices. The high productivity combinatorial technique can provide a compatibility evaluation of photoresist strip chemicals with high-k devices.

The invention discloses a method for cleaning residues from a semiconductor substrate during a nickel platinum silicidation process. Post silicidation residues of nickel and platinum may not be removed adequately just by an aqua regia solution (comprising a mixture of nitric acid and hydrochloric acid). Therefore, embodiments of the invention provide a multi-step residue cleaning, comprising exposing the substrate to an aqua regia solution, followed by an exposure to a chlorine gas or a solution comprising dissolved chlorine gas, which may further react with remaining platinum residues, rendering it more soluble in aqueous solution and thereby dissolving it from the surface of the substrate.
