In a collaborative effort, scientists have innovated a groundbreaking etching process that harnesses hydrogen fluoride plasma to double the etching efficiency of silicon material vertical channels. This remarkable advancement enables the achievement of 640 nanometers of etching depth in a mere 60 seconds. The process meticulously punctures through alternating layers of silicon oxide and silicon nitride, exposing these layered materials to the plasma. By integrating chemicals like phosphorus trifluoride, the process can be fine-tuned for even greater efficacy. Furthermore, the strategic addition of an appropriate amount of water effectively mitigates the impact of byproducts. These pioneering developments promise to usher in more sophisticated manufacturing processes for 3D NAND flash memory technology, enhancing storage density, lowering costs, and accelerating data transmission speeds.
