A collaborative team of US and Chinese scientists has reported a notable advance in semiconductor manufacturing with the development of a new fabrication method using perovskite materials. According to a peer reviewed study, this method offers reduced costs, lower energy consumption, and simpler production steps compared with traditional silicon based processes. By using perovskite crystalline compounds, known for their optoelectronic properties and ease of processing, researchers have created a pathway for semiconductor devices that could be more accessible and sustainable for future applications.
Unlike conventional wafer fabrication, the new approach focuses on precise thin film deposition and controlled electronic properties across perovskite layers. This results in uniform crystal quality suitable for high performance devices while avoiding many limitations of standard methods, such as expensive lithography and high temperature processing. Laboratory tests of prototype devices produced through this method demonstrated stable electrical performance, competitive switching characteristics, and good charge mobility, highlighting potential applications in both digital and analog electronics. Researchers note that this fabrication route could allow producers to scale perovskite devices using existing infrastructure with minimal modification.
While perovskite semiconductors have been explored for niche applications including solar cells, LEDs, and photonic devices, reproducible and scalable production has remained a challenge. Zhang Shuchen, a materials scientist at University of Science and Technology of China and lead author of the study, shared with Xinhua that their work establishes a new material platform and design approach for high performance luminescent and display devices. Experts emphasize that advanced chip manufacturing is still heavily dependent on complex and costly equipment, such as EUV lithography and precision etching tools, which creates bottlenecks for producing smaller and more intricate device architectures. The perovskite approach addresses several of these structural constraints, offering a lower energy and simplified alternative.
Researchers highlighted that sustainability is a key advantage of the new method, as energy requirements are significantly reduced compared with conventional semiconductor fabrication. The next steps for the technology include improving long term stability under various operating conditions, refining device architectures, integrating perovskite layers with existing semiconductor platforms, and preparing supply chains for scale. Collaborations among academic institutions, materials companies, and chip foundries are expected to accelerate progress, with the ultimate goal of expanding production capabilities beyond the current limits defined by Moore’s Law. Proof of concept demonstrations suggest that perovskite semiconductors are closer to commercial application than ever, and continued development may see them integrated into a wider range of electronic devices in the coming years.
