Resin Composition for Microlens Etching Rate Matching

The patent modifies the chemical composition parameters of the thermosetting resin by incorporating specific functional groups (carboxy, hydroxy, amino groups) in controlled ratios. This changes the etching rate parameter to match the resist layer while maintaining other critical properties like heat resistance and transparency.

The patent creates a composite resin system combining thermosetting base resin with added functional components (carboxy-containing compounds, hydroxy-containing compounds, amino-containing compounds). This composite structure achieves the desired etching rate matching while preserving the inherent advantages of thermosetting resins.

The patent adjusts the chemical parameter of the resin by introducing functional groups with specific thermal and chemical stability characteristics. These modified parameters enable the resin to withstand high-temperature processing without deformation or exfoliation while maintaining compositional stability.

The patent enhances specific local properties of the resin by concentrating functional groups (carboxy, hydroxy, amino) in strategic positions within the molecular structure. This local enhancement provides targeted resistance to thermal and chemical degradation at critical stress points during processing.

The patent enables the resin to perform its own cross-linking function through self-crosslinkable functional groups (carboxy, hydroxy, amino groups) that react under processing conditions without requiring external cross-linking agents. This self-service mechanism ensures cross-linking occurs only when needed, maintaining storage stability while achieving heat resistance.

The patent incorporates pre-reactive functional groups into the resin structure during manufacturing, but these groups remain dormant during storage. Under high-temperature processing conditions, these pre-positioned groups become activated and perform the cross-linking action, providing heat resistance without compromising storage stability.

The patent creates a composite resin formulation combining thermosetting base material with functional additives (carboxy-containing, hydroxy-containing, and amino-containing compounds). This composite structure provides simultaneous improvement in solvent resistance and flatness while maintaining the heat resistance inherent to thermosetting resins.

The patent modifies multiple chemical parameters of the resin system by introducing functional groups with specific molecular characteristics. These parameter changes collectively enhance solvent resistance through improved molecular interactions and achieve better flatness through controlled curing shrinkage, while preserving heat resistance.
