A main object of the present invention is to provide a resin composition having high heat resistance and a low dielectric constant, a varnish thereof, a resin film thereof and a semiconductor device using the same.
In the present invention, the object is achieved by a resin composition comprising a compound having a structure represented by formula (1) and a crosslinking agent:
wherein in formula (1), R
0
is a single bond or has a structure represented by formula (2); R
1
to R
8
are respectively any of hydrogen, a group having an alicyclic structure, an organic group having 1 to 10 carbon atoms other than the group having an alicyclic structure, a hydroxyl group and a carboxyl group; and “X” is any of —O—, —NHCO—, —CONH—, —COO— and —OCO—; further, wherein in formula (2), “Ar” is an aromatic group; “Y” is any of a single bond —O—, —S—, —OCO— and —COO—; “q” is an integer of 1 or more; R
9
is hydrogen or an organic group having 1 or more carbon atoms and may be identical with or different from each other when “q” is an integer of 2 or more; at least one of R
1
to R
8
is the group having an alicyclic structure when R
0
is a single bond; at least one of R
1
to R
9
is the group having an alicyclic structure when R
0
has the structure represented by formula (2); and “*” and “**” represent a position to be bonded to a different chemical structure.
