Single source metalloorgranic precursors to type 14-16 semiconductors

摘要

The present invention relates to a single source metalloorganic precursor compound of the formula:PP(2-NR- Q-).sub.l M-A. sub.m (I=0-4, m=0-4, l+m=2 or 4)PPwherein M is selected form the Group 14 elements of Germanium, Tin or Lead; PPA and R are independently selected from: amide, alkyl having from 1 to 20 carbon atoms, aryl, substituted aryl, or -Q'-2-NR'L. sub.n (n=1-4) wherein L is selected from nothing or a Lewis base ligand; PPQ and Q' are each independently selected from Group VIa elements of sulfur, selenium, or tellurium; andPP2-NR and 2-NR' are each independently selected from N-heterocyclic aryl or its derivatives. PPMethods of producing these compounds are also disclosed. These precursor materials provide in a single compound the binary, tertiary, or quaternary metals in a ratio to each other that is controllable by a judicious choice of metal atoms and organic substituents. The metal alloys are useful in a variety for electronic applications, particularly in semiconductors and solar energy.
