Title: Selective extn. of ammonium cpds. from aq. medium - by forming a complex with a phenyl phosphine oxide cpd. ligand
IPC: C07F9/53
Filed: 1979-04-24
Abstract: Ammonium cpds. are selectively extracted using a cpd. contg. a unit (I) in which n = 2-6. pds. (I) give good selective extn. of ammonium cpds. such as salts of ammines, amino acids and amino acid esters from aq. solns. Pref. cpd. (I) is of formula (Ia). ref. the complexing agent is dissolved in a water-immiscible organic solvent such as Et2O, dichloromethane or trichloromethane, thesoln. is shaken with the aq. soln. contg. the ammonium cpd., and the organic layer contg. the complexed ammonium cpd. is recovered. Cpds. (I) are made by reacting diphenylphosphorus chloride with o-anisylmagnesiumbromide and oxidising the prod. to o-anisyldiphenylphosphine-oxide. This is converted into the corresp. o-hydroxyphenyldiphenylphosphine oxide, which is then reacted with a cpd. Br(CH2)n-O (1) which opt. contains a protective gp. If necessary, the protective gp. is finally removed by hydrolysis. Extn. takes place by complexing of the ammonium gp. by hydrogen bonding with >=1 phosphine oxide unit and an O atom of the side chain.

Title: Hydrogen treatment of semiconductor-insulator interface - by heat treating after depositing silicon or its nitride from hydrogen-contg. plasma
IPC: H01L21/314
Filed: 1980-02-29
Abstract: Hydrogen treatment of semiconductor devices comprising an insulating layer on a semiconductor substrate is carried out by (a) depositing a layer of a material (I) comprising Si nitride and/or amorphous Si on the insulating layer from an H-contg. plasma, and (b) heat treating the device at a temp. higher than that in step (a). (I) acts as a source of H for reaction with free electrons at the semiconductor/insulator interface; the H diffuses through the insulating layer during heat treatment and is retained irreversibly at the interface, thereby giving time-stable improvement in properties.
