    - 1 - Hafnium Nitrate Precursor Synthesis and HfO2 Thin Film Deposition WEIWEI ZHUANG,1 JOHN F. CONLEY,1 YOSHI ONO,1 DAVID R. EVANS1 AND R. SOLANKI2 1Sharp Laboratories of America, 5700 Pacific Rim Blvd Camas, WA 98607 2Oregon Graduate Institute, Beaverton, OR, 97006 The paper will introduce a simple new method on the synthesis of both hafnium and zirconium nitrate precursors. The intermediate product, dinitrogen pentoxide produced from the water extraction from fume nitric acid via phosphorus pentoxide, was condensed by liquid nitrogen trap into a flask equipped with hafnium or zirconium tetrachloride. To give the high yield, the mixture of fume nitric acid and phosphorus pentoxide was heated to a certain temperature, from which large quantity of dinitrogen pentoxide had been generated. In the following step, hafnium or zirconium tetrachloride was refluxed over dinitrogen pentoxide at 30 to 35 oC for half- hour. The product was purified by sublimation. High yield, above 95%, was obtained. The cost for the hafnium nitrate precursor synthesis was estimated. The precursor was not stable at room temperature, and should be stored in refrigerator in sealed vials. No chlorine was detected from both EDS and chemical analysis. The volatility was evaluated by thermal gravity analysis. For high k thin film applications, the precursors were evaluated through the hafnium oxide thin film deposition via ALD process. High quality hafnium oxide thin films were obtained. The hafnium oxide thin film property consistence using different batches of our synthesized hafnium nitrate precursor was also verified. X-ray diffraction analysis indicated the films were smooth, uniform, amorphous as deposited and monoclinic after post annealing.

ALFREDSON October 1970 ISBN 0 642 99394 7 AUSTRALIAN ATOMIC ENERGY COMMISSION RESEARCH ESTABLISHMENT LUCAS HEIGHTS REVIEW OF PROCESSES FOR THE PRODUCTION OF HAFNIUM-FREE ZIRCONIUM by Dc ROYSTON Pa G, A.LFREDSON ABSTRACT The three main industrial processes for the production of hafnium-free zirconium are described in terms of their head-end,, zirconium-hafnium separation and zirconium metal forming steps. Possible improvements and alternative processes are outlined. Zirconium-hafnium separation schemes based on selective reduction of the chlorides or distillation and sublimation techniques show the most promise for future development in competition with the established hexone-thiocyanate and TBP-nitric acid solvent extraction schemes. Head-end steps involving direct chlorination of zircon in fluidised beds or caustic fusion and metal production via electrowinning warrant further development. CONTENTS Page 1. INTRODUCTION 1 2.

Childs3 · Henrik Braband3 · Laurent Bigler3 · Urs Stalder3 · Roger Alberto3 · Philippe F. Weck4 · Frederic Poineau1 © Springer Nature Switzerland AG 2019 Abstract Zirconium tetrachloride was synthesized from the reaction between zirconium metal and chlorine gas at 300 °C and was analyzed by electron impact mass spectrometry (EI-MS). Substantial fragmentation products of ZrCl4 were observed in the mass spectra, with ZrCl3 being the most abundant species, followed by ZrCl2, ZrCl, and Zr. The predicted geometry and kinetic stability of the fragments previously mentioned were investigated by density functional theory (DFT) calcu- lations. Energetics of the dissociation processes support the most stable fragment to be ZrCl3 while the least abundant are ZrCl and ZrCl2.
