摘要:
A highly aqueous acidic cleaning composition for copper oxide etch removal from Cu-dual damascene microelectronic structures and wherein that composition prevents or substantially eliminates copper redeposition on the Cu-dual damascene microelectronic structure.
摘要:
A highly aqueous, strongly basic planarizing solution and a process for its use to reducing or essentially eliminating protrusions or projections extending generally upwardly from a generally planar surface of polysilicon film produced by Low Temperature Poly Si (LTPS) annealing a film of amorphous silicon deposited on a substrate; the process including contacting the surface of the generally planar polysilicon film with the highly aqueous, strongly basic solution for a time sufficient to selectively etch the protrusions or projections from the surface of the generally planar polysilicon film without any significant etching of the generally planar polysilicon film, said highly aqueous, strongly basic solution being a solution having a pH of 12 or higher and comprising water, at least one strong base, and at least one etch rate control agent.

摘要:
There is provided a lens module. The lens module according to the present invention may include a lens unit including one or more lenses, each having a lens function part and a flange part forming a circumference of the lens function part; and a piezoelectric body disposed on the flange part so as to shield unnecessary light incident through the lens unit and performing autofocusing according to an application of voltage thereto.
