Abstract: Disclosed is a method for manufacturing a high-density neural probe including needles having various forms. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.
