Claim 19:
20. A method of forming a material layer, the method comprising:
a deposition cycle comprising:
providing an adsorption inhibitor on a substrate;
purging an excess amount of the adsorption inhibitor;
providing a metal precursor on the substrate;
purging an excess amount of the metal precursor; and
supplying a reactant to form a material layer on the substrate,
wherein the adsorption inhibitor includes a group 15 element or a group 16 element, and
wherein:
the adsorption inhibitor has a structure of X1—C(═O)—X2 or X1—C(═S)—X2, wherein X1 and X2 are each independently hydrogen, an alkyl group having 1 to 10 carbons, an alkenyl group having 2 to 10 carbons, an alkynyl group having 2 to 10 carbons, an aryl group having 6 to 15 carbons, a cycloalkyl group having 3 to 12 carbons, a cycloalkenyl group having 3 to 12 carbons, —OR1, —NR1R1′, or —SR1, provided that at least one of X1 and X2 is not hydrogen, and optionally X1 and X2 together form a ring, and R1 and R1′ are each independently hydrogen, an alkyl group having 1 to 5 carbons, an alkenyl group having 2 to 5 carbons, an alkynyl group having 2 to 5 carbons, an aryl group having 6 to 10 carbons, a cycloalkyl group having 3 to 7 carbons, or a cycloalkenyl group having 3 to 7 carbons; or
the adsorption inhibitor has a structure of X1-QO—X2, X1-QO2—X2, or (QO)X1X2X3, wherein Q is oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), or bismuth (Bi), X1, X2, and X3 are each independently hydrogen, an alkyl group having 1 to 10 carbons, an alkenyl group having 2 to 10 carbons, an alkynyl group having 2 to 10 carbons, an aryl group having 6 to 15 carbons, a cycloalkyl group having 3 to 12 carbons, a cycloalkenyl group having 3 to 12 carbons, —OR1, —NR1R1′, or —SR1, provided that at least one of X1, X2, and X3 is not hydrogen, and optionally at least two of X1, X2, and X3 together form a ring, and R1 and R1′ are each independently hydrogen, an alkyl group having 1 to 5 carbons, an alkenyl group having 2 to 5 carbons, an alkynyl group having 2 to 5 carbons, an aryl group having 6 to 10 carbons, a cycloalkyl group having 3 to 7 carbons, or a cycloalkenyl group having 3 to 7 carbons; or
the adsorption inhibitor has a structure of Dm(RR′R″), wherein D is nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), or bismuth (Bi), m is 1 or 2, R, R′, and R″ are each independently hydrogen, an alkyl group having 1 to 10 carbons, an alkenyl group having 2 to 10 carbons, an alkynyl group having 2 to 10 carbons, an aryl group having 6 to 15 carbons, a cycloalkyl group having 3 to 12 carbons, or a cycloalkenyl group having 3 to 12 carbons, provided that at least one of R, R′, and R″ is not hydrogen, and optionally two or more of R, R′, and R″ together form a ring.
