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.
