Abstract of CA2539556
This invention relates to a method for producing group IB-IIIA-VIA quaternar y 
or higher alloy semiconductor films wherein the method comprises the steps o f 
(i) providing a metal film comprising a mixture of group IB and group IIIA 
metals; (ii) heat treating the metal film in the presence of a source of a 
first group VIA element (said first group VIA element hereinafter being 
referred to as VIA1 ) under conditions to form a first film comprising a 
mixture of at least one binary alloy selected from the group consisting of a 
group IB -VIA1 alloy and a group IIIA~-VIA1 alloy and at least one group IB- 
IIIA-VIA1 ternary alloy (iii) optionally heat treating the first film in the 
presence of a source of a second group VIA element (said second group VI 
element hereinafter being referred to as VIA2) under conditions to convert t he 
first film into a second film comprising at least one alloy selected from th e 
group consisting of a group IB-VIA1-VIA2 alloy and a group IIIA-VIA1-VIA2 
alloy; and the at least one group IB-~III-VIA1 ternary alloy of step (ii); (iv) 
heat treating either the first film or second film to form a group IB- IIIA-VIA 
quaternary or higher alloy semiconductor film.
