WHAT IS PIEZO-ON-INSULATOR (POI)?
Piezo-On-Insulator (POI) is a material structure with significant application value in the fields of semiconductors. Structurally, it mainly consists of three layers: the bottom layer is typically high-resistivity silicon (or other suitable insulating substrate materials), the middle layer is a buried oxide layer functioning as isolation and electrical-property adjustment, and the top layer is a thin and uniform single-crystal piezoelectric material. This design endows POI with excellent electrical insulation and piezoelectric properties. The market is experiencing rapid growth driven by the deepening commercialization of 5G, demanding higher operating frequencies, wider bandwidths, and lower temperature sensitivity in RF filters. Furthermore, opportunities emerge from smartphone front-end module changes, integrated antenna multiplexers, and emerging uses in high-frequency ultrasonic transducers and self-powered sensors. Leading players include France’s Soitec and China’s Jinan Jingzheng Electronics (NANOLN). For instance, Soitec launched its POI substrate in 2019 using proprietary Smart Cut™ technology and has achieved mass production with capacity up to 700,000 wafers per year. Similarly, NANOLN pioneered 3-inch nano-thickness lithium niobate thin films in 2014 and is expanding with a new line for 100,000 wafers annually. POI wafers provide over 20% better electromechanical coupling than bulk piezoelectric materials, enhancing device efficiency.
