Pi Square Instruments specializes in the design and development of Atomic Layer Deposition (ALD) equipment. ALD is an indispensable thin-film process technology in the advanced semiconductor, display, optoelectronics, and energy industries. It enables the precise, layer-by-layer deposition of thin films at the atomic scale, achieving uniformity, step coverage, and film thickness control that are difficult to attain with traditional processes. As process nodes continue to shrink and device structures become increasingly three-dimensional and complex, the importance of ALD and market demand for it are rapidly rising. In this critical field, the company is investing in the independent development of Photo-Induced Atomic Layer Deposition (PI-ALD) technology, which uses light energy to drive surface reactions, thereby enabling coating solutions that operate at lower temperatures, with higher efficiency, and greater process flexibility. The company is not merely an equipment supplier; it aspires to become the technology leader defining next-generation thin-film processes.
