CONSTITUTION: A method of forming the gate insulation film of a semiconductor device comprises steps of: forming an insulation film(22) on a semiconductor substrate(21); forming a nitride layer(22a) by injecting nitrogen ions into the top surface of the insulation film(22); defining the insulation film(22) into a first region and a second region using a photomask; removing the nitride layer(22a) in the second region and then continuously removing the insulation film(22) up to a prescribed depth thereof; removing the photomask; removing the nitride layer(22a) in the first region and at the same time removing the second insulation film(22b) to expose the substrate corresponding to the second region; forming a gate insulation film(22d), having the first thickness in the first region by an oxidation process; and forming a gate insulation film(22e), having the second thickness less than that of the first thickness.

Title: Method for producing electrically zinc-plated steel sheet of excellent surface appearance
Inventor: KWAK YEONG JIN
IPC: C25D3/22

Abstract: PURPOSE: A method is provided to produce electrically zinc-plated steel sheet of excellent surface appearance by restraining elution of iron from steel sheet due to low pH and by preventing charge of iron in a plated layer when plating with zinc electrically. CONSTITUTION: A zinc-plated steel sheet is produced by using a horizontal electrical plating facility using insoluble anode of bath in sulfate of zinc. Sodium iodide and potassium iodide of 0.0003mol/l-1mol/l is added to the plating bath to restrain melting of iron ions from the steel sheet. The difference of whiteness due to partial charge of iron occurring in phosphate treatment is restrained. Thereby, electrically zinc-plated steel sheet of excellent surface appearance is obtained.
