Abstract: A method paring a stable, dilute aqueous solution of at least one 3-isothiazolone compound comprising 5-chloro-2-methyl-3-isothiazolone, the concentration of said compound(s) in said solution being about 0.5 to 5% by weight based on solution, comprising introducing about 0.1 to 5% by weight based on said solution, of a ferric salt as the stabilizer is disclosed. Dilute aqueous solutions of about 0.5 to 5.0 parts by weight of at least one 3-isothiazolone compound comprising 5-chloro-2-methyl-3-isothiazolone, about 0.1 to 2.5 parts by weight of a stabilizing, water soluble, non-chelated ferric salt, and about 92 to 99 parts by weight of aqueous solvent, are also disclosed.

Abstract: The present invention provides a method of stabilizing non-halogenated 3-isothiazolones in aggressive systems with pH above 8.5. The invention also discloses compositions with pH above 8.5, containing non-halogenated 3-isothiazolones and an effective stabilizing amount of a iodine-containing stabilizer.

Abstract: A structure and method for forming an isolation wall in an etched trench are described. The trench walls are covered by a thin silicon oxide layer and the trench conformally filled with an oxy-nitride mixture having a particular range of composition so as to produce a neutral to slight tensile stress in the oxy-nitride relative to silicon. The structure is very simple to fabricate and creates fewer defects in the silicon substrate than prior art techniques. Buried voids in the filled trench are eliminated.
