112 SMT007 MAGAZINE I FEBRUARY 2021 models of new molecules and predicting their properties suitable for the best PAGs. • Test: Once suitable candidates have been discovered, these new molecules can be synthesized in robot-laboratories like IBM's RoboRXN Autonomous Lab. ese totally new materials can be tested, and their results added to current knowledge. • Iterate: If the new material is not suitable, the process loop can be entered once again until one is found. is is a real story, and the IBM's RoboRXN Autonomous Lab has been used by 21,189 sci- entists, hypothesizing over 2.5 million chemi- cal reactions to synthesize 458 new materials since October 1, 2020. Accelerated discovery is here. SMT007 As an example, if this loop were applied to the problem of new materials, say a new pho- topolymer-resist capable of sub-nanometer geometries for integrated circuit production for the future, how would that work? Using the scientific method, it could look like this: • Study: Using super computers to deep search all available research literature in the world for "photo acid generators" (PAG—the key component of photore- sists), 10,000 times more information is digested and structured than done by a human. All the information on PAGs can be organized into classes and family of molecules and displayed as a "circular dendrogram" about PAGs. • Hypothesize: Using AI-based simulation to examine each PAG molecule to under- stand what could exist in the gaps on the dendrogram then creating AI generative Figure 22: Accelerated discovery will provide a foundation for discovery-driven enterprises.
