Abstract

A coating film forming composition includes an amino acid generator including a protecting group that is eliminated to generate an amino acid. A coating film forming composition includes a component (A): the amino acid generator; a component (B): a hydrolyzable silane, a hydrolysis product thereof, a hydrolysis-condensation product thereof, or a mixture thereof; and a component (C): a solvent.

First claim

What is claimed is:

1. A coating film forming composition comprising:
a component (A): an amino acid generator comprising a protecting group that is eliminated to generate an amino acid;
a component (B): a hydrolyzable silane, a hydrolysis product thereof, a hydrolysis-condensation product thereof, or a mixture thereof; and
a component (C): a solvent,
wherein the amino acid generator is at least one type of compound selected from the group consisting of compounds of Formula (2-1) to Formula (2-22):

where:
D is the protecting group and is one selected from the group consisting of a tert-butoxycarbonyl group and a 9-fluorenylmethoxycarbonyl group.

2. The coating film forming composition according to claim 1 , wherein the amino acid generator is a thermo amino acid generator comprising a protecting group that is eliminated by heat to generate an amino acid.

3. The coating film forming composition according to claim 1 , wherein the amino acid generator is a photo amino acid generator comprising a protecting group that is eliminated by light to generate an amino acid.

4. The coating film forming composition according to claim 1 , wherein the component (B) is at least one selected from the group consisting of a hydrolyzable silane, a hydrolysis product thereof, a hydrolysis-condensation product therefore, and a mixture thereof, wherein the hydrolysable silane is selected from the group consisting of Formula (3) and Formula (4):
R 3 a Si(R 4 ) 4-a   Formula (3)

where:
R 3 is an alkyl group, an aryl group, a halogenated alkyl group, a halogenated aryl group, an alkenyl group, or an organic group having an epoxy group, an acryloyl group, a methacryloyl group, a mercapto group, an amino group, a carboxy group, a phosphate group, an amide group, a nitro group, an acyl group, a sulfonic group, a cyano group, or a combination thereof;
R 3 is bonded to a silicon atom through a Si—C bond;
R 4 is an alkoxy group, an acyloxy group, or a halogen atom; and
a is an integer of 0 to 3,
[R 5 c Si(R 6 ) 3-c ] 2 Y b   Formula (4)

where:
R 5 is an alkyl group, an aryl group, a halogenated alkyl group, a halogenated aryl group, an alkenyl group, or an organic group having an epoxy group, an acryloyl group, a methacryloyl group, a mercapto group, an amino group, a carboxy group, a phosphate group, an amide group, a nitro group, an acyl group, a sulfonic group, a cyano group, or a combination thereof;
R 5 is bonded to a silicon atom through a Si—C bond;
R 6 is an alkoxy group, an acyloxy group, or a halogen atom;
Y is an alkylene group or an arylene group;
b is an integer of 0 or 1; and
c is an integer of 0 or 1.

5. The coating film forming composition according to claim 4 , wherein the hydrolysable silane is Formula (3), where a is 0 to 2.

6. The coating film forming composition according to claim 4 , further comprising a crosslinkable compound as a component (D).

7. The coating film forming composition according to claim 6 , wherein the crosslinkable compound has at least two functional groups of Formula (D-1):
—CH 2 —O—R 1   Formula (D-1)

where R 1 is a hydrogen atom or a C 1-10 alkyl group.

8. The coating film forming composition according to claim 6 , wherein:
the crosslinkable compound has Formula (D-2) or Formula (D-4):

where R 6 is a hydrogen atom, a C 1-10 alkyl group, an aryl group, an aralkyl group, an alkenyl group, or a functional group of Formula (D-3):

where R 7 is a hydrogen atom or a functional group of Formula (D-1):
—CH 2 —O—R 1   Formula (D-1),

and
Formula (D-2) has two to six functional groups of Formula (D-1),

R 8 is a hydrogen atom or a functional group of Formula (D-1),
Formula (D-4) has two to four functional groups of Formula (D-1).

9. An electronic device comprising a film formed from the coating film forming composition as claimed in claim 1 .

10. A solid state imaging device comprising a charge coupled device (CCD) or a complementary metal oxide film semiconductor (CMOS) that comprises a film formed from the coating film forming composition as claimed in claim 1 .

11. A solid state imaging device comprising a film formed from the coating film forming composition as claimed in claim 1 as a planarization layer on a color filter.

12. A solid state imaging device comprising a film formed from the coating film forming composition as claimed in claim 1 as a planarization layer or a conformal layer on a microlens.
