Despite thedevelopment of various mechanical and non-mechanical machining methods, achieving the high-efficiency, high-precision fabrication of MNFS from difficult-to-cut materials remains a significant technical challenge. This reviewbegins with an introduction to typical artificial MNFSs and their stringent requirements and then provides acomprehensive survey of MNFSs, focusing on etching methods. In particular, plasma etching demonstrates notableadvantages in MNFS fabrication. However, two critical challenges persist: accurately controlling topographicalinformation during pattern transfer in plasma etching and achieving high-quality, uniform patterning masks overlarge areas. These issues are addressed by thoroughly analyzing and summarizing the modeling of plasma etchingand the simulation of feature profiles. Various hybrid etching machining (HEM) strategies, including laser andetching combined machining, cutting and etching combined machining, molding and etching combined machining,and self-assembly and etching combined machining, are categorized and compared in detail to facilitate themanufacturing of complex MNFSs. Finally, this review summarizes current deficiencies and future challenges ofHEM, laying the groundwork for further advancements in MNFS fabrication and intelligent HEM technologies.展开更多
