Company profile
researched Aug 2026Alsemy Inc is a Korea-based company applying artificial intelligence to semiconductor modeling, simulation and manufacturing optimization. It markets three products: Alsis, which generates neural network-based device compact models intended to support accurate circuit simulation; Alsphere, a platform for optimizing semiconductor manufacturing through process modeling simulation and reverse engineering; and Alscope, a platform for semiconductor design and manufacturing optimization aimed at collaboration across the industry ecosystem and at accelerating design-technology co-optimization (DTCO) simulation.
Alongside its commercial products, the company participates in academic research on advanced transistor architectures. Alsemy researchers co-authored a 2024 paper with Hanyang University evaluating the impact of strain on sub-3 nm gate-all-around CMOS logic circuit performance using a neural compact modeling approach trained on 3D simulation data, and a 2025 paper with Sungkyunkwan University exploring optimal transition metal dichalcogenide (TMDC, specifically MoS2) multi-nanosheet GAA-FET architectures for the 0.7 nm technology node.

Market position
Alsemy positions its tools within the semiconductor modeling and simulation segment, addressing device compact modeling, process optimization and DTCO. Its research output with Korean universities has been indexed by trade publication Semiconductor Engineering, and NVIDIA published material on the company's use of physics-informed AI for chip modeling.
Technology
The company's core approach is the use of neural networks and physics-informed AI to replace or accelerate conventional semiconductor modeling workflows. Alsis produces neural network-based device compact models for circuit simulation; Alsphere applies AI to process modeling simulation and reverse engineering of manufacturing processes; and Alscope targets AI-accelerated DTCO simulation. Published work with university collaborators applies neural compact modeling to sub-3 nm gate-all-around CMOS devices and to TMDC-channel multi-nanosheet FET architectures at sub-1 nm nodes.
