Abstract
A method, including: obtaining a set of conditions for a resist development model for simulating a resist development process of a resist layer; and performing, by a hardware computer system, a computer simulation of the resist development process using the set of conditions and the resist development model to obtain a characteristic of the development of the resist layer, wherein the computer simulation separately simulates different certain different physical and chemical processes and characteristics of the resist development process.

A method, comprising:
- obtaining a set of conditions for a resist development model for simulating a resist development process of a resist layer;
- and
- performing, by a hardware computer system, a computer simulation of the resist development process using the set of conditions and the resist development model to obtain a characteristic of the development of the resist layer, wherein the computer simulation is configured to simulate certain different physical and chemical processes and characteristics of the resist development process separately.
A non-transitory computer program product comprising machine-readable instructions therein, the instructions, upon execution by a computer system, configured to cause the computer system to at least:
- obtain a set of conditions for a resist development model for simulating a resist development process of a resist layer;
- and
- perform a computer simulation of the resist development process using the set of conditions and the resist development model to obtain a characteristic of the development of the resist layer, wherein the computer simulation is configured to simulate certain different physical and chemical processes and characteristics of the resist development process separately.
