Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A method of manufacturing a semiconductor device, comprising:
forming a conductive layer over a substrate having a plurality of protrusions and recesses,
wherein the conductive layer is formed over the protrusions and in the recesses;
forming a protective layer over the conductive layer,
wherein the protective layer includes a polymer composition including a polymer comprising repeating units of one or more of:, wherein a, b, c, d, e, f, g, h, and i are each independently H, —OH, —ROH, —R(OH)2, —NH2, —NHR, —NR2, —SH, —RSH, or —R(SH)2, wherein at least one of a, b, c, d, e, f, g, h, and i on each repeating unit is not H,
wherein R, R1, and R2 are each independently a C1-C10 alkyl group, a C3-C10 cycloalkyl group, a C1-C10 hydroxyalkyl group, a C2-C10 alkoxy group, a C2-C10 alkoxy alkyl group, a C2-C10 acetyl group, a C3-C10 acetylalkyl group, a C1-C10 carboxyl group, a C2-C10 alkyl carboxyl group, or a C4-C10 cycloalkyl carboxyl group, and
n is 2-1000;
forming a resist layer over the protective layer;
patterning the resist layer; and
forming a conductive contact over the conductive layer.
