Abstract

PURPOSE:To prevent a change of a performance due to prebacking and postbacking the titled composition at a high temp. and to obtain a good compatibility against a deposition of a photoabsorbent during a storage, thereby enabling a good fine working. CONSTITUTION:The titled photoresist composition contains a compd. shown by the formula wherein R1 and R2 are each a hydrogen atom, 1-20C an alkyl, or 6-20C an aryl group, R1 and R2 may form a ring but can not be both hydro gen atoms, R3 and R4 are each a cyano, -COR5, -COOR5, and -SO2R5 groups, R5 and R6 are each 1-20C an alkyl, or 6-20C an aryl group, R3 and R4 together with each other may form a 5-6 membered ring, (n) is 1 or 2. When (n) is 2, any of R1, R2 and R5 groups are an alkylene or an arylene group and may form a bis-compd. The above described photoabsorbent is easily soluble to an org. solvent such as xylene, and has a good compatibility against the resist and does not occur a sublimation at a high temp. By compounding said photoabsorbent, the excellent antihalation effect and a fine pattern with a good reproducibility are obtd.

``Prior art'' Electronic components such as semiconductors, ICs, and LSIs are manufactured by drawing an arbitrary circuit pattern using optical means, exposing the resist to light through a mask, developing it, and etching the substrate. . In recent years, as integrated circuits have become more highly integrated,
Progress has been made in making patterns finer. For this reason, it is desired to form fine patterns on resists with high precision.

However, in the above method, due to diffraction of the exposing light and scattering and reflection of the light from the surface of the underlying silicon substrate,
The resolution of the resist image is significantly affected. In particular, when using a substrate with aluminum vapor-deposited on the surface of a silicon wafer, the light reflectance of the aluminum surface is high.
Therefore, the halation light becomes large, and if there is a step on the substrate as well as a flat part of the surface, diffuse reflection will occur at that part, making it difficult to accurately reproduce a thin line width pattern of several μm. Rarely.

However, when using a solvent-based resist, it is necessary to remove residual solvent by baking the applied resist, but some light absorbers may sublimate during baking and the concentration may drop, making it impossible to obtain a satisfactory light absorption ability. However, there was a drawback that the light absorbing agent precipitated during storage, resulting in variations in effectiveness.

Furthermore, with the aim of improving these drawbacks, light absorbing agents were investigated, and published in Japanese Patent Application Laid-open No. 3-36737 and Japanese Patent Publication No. 3-36737. ? -/74t?
Phenylazobenzene derivatives such as those seen in No. 4t/ have been proposed.

The compounds of the present invention are easily dissolved in organic solvents such as xylene, ethyl cellosolve, cyclohexanone, cellosolve acetate, butyl acetate, etc., and have good compatibility with rubber photoresists, positive photoresists, and deep UV resists, even at high temperatures. Since they do not exhibit sublimation even when baked, when they are added, fine patterns can be obtained with good reproducibility due to their excellent antihalation effect. Therefore, if the compound of the present invention is used, the solvent can be completely removed by pre-baking, so the uniformity of the resist film will not be affected by residual solvent, and even if stored for a long time after pre-baking, the compound will not precipitate and the film will be defective. Uniformity can be avoided. ``Example'' Next, the present invention will be described in detail with reference to Examples, but the present invention is not limited thereto.
