Computational Lithography for Silicon Photonics Design

open access: yesIEEE Journal of Selected Topics in Quantum Electronics, 2020
A lithography model is built using physical measurements obtained from a fabricated test pattern. The method is able to accurately predict the proximity and smoothing effects characteristic of a 193~nm deep-ultraviolet (DUV) lithography process. The accuracy of the model is verified by visually inspecting the fabricated test patterns and comparing them

AI Computational Lithography

2020 China Semiconductor Technology International Conference (CSTIC), 2020
Machine learning based computational lithography is intended to accelerate the speed of the solutions significantly. There are three critical aspects of AI computational lithography: (1). The feature vector design, (2). The approximate mapping function construction, (3). The model training scheme.

Inverse e-beam lithography on photomask for computational lithography

Journal of Micro/ Nanolithography, MEMS, and MOEMS, 2013
Computational lithography, e.g., inverse lithography technique (ILT) and source mask optimization, is considered necessary for the “extremely low k1” lithography process of sub-20 nm device node. The ideal design of a curvilinear mask for computational lithography requires many changes during photomask fabrication.

Development of a computational lithography roadmap

Proceedings of SPIE, 2008
While lithography R&D community at large has already gotten the mind set for 32nm, all eyes are on 22nm node. Current consensus is to employ computational lithography to meet wafer CD uniformity (CDU) requirement. Resolution enhancement technologies (RET) and model OPC are the two fundamental components for computational lithography.
