DJEL

DJEL provides both hardware equipment and software solutions aimed at improving production efficiency and yield for semiconductor manufacturers. Its client base consists of major semiconductor design and fabrication companies, primarily within China. The business model centers on the development and sale of proprietary equipment and software that are critical for advanced chip manufacturing processes. This strategy positions DJEL as a key domestic supplier in China's effort to build a self-sufficient semiconductor industry. The company was designated a national-level "little giant" in 2021, a status that often precedes substantial investment and growth expectations.

The company's product portfolio includes a range of specialized equipment and software for IC yield management. Hardware offerings feature nano-scale electron beam inspection (EBI) systems for defect detection, critical dimension scanning electron microscopes (CD-SEM) for measurement, and defect review SEM (DR-SEM) equipment. On the software side, DJEL develops computational lithography (EDA) products, specifically Optical Proximity Correction (OPC) software, which is essential for optimizing the lithography process in printing fine circuit patterns. One of its core concepts is the HPO™ (Holistic Process Optimization) platform, a DTCO (Design Technology Co-optimization) solution designed to integrate and optimize the entire process from chip design to manufacturing for yield maximization. The company has also developed a yield data management platform, YieldBook, and a strict lithography simulation software, PanGen Sim®.
