A glass die, a micro replication characteristic of PDMS and an electroplating technology are used to make the three-dimensional microelectrode array. A precise cutting machine is used to cut the glass to form a column array and a mixture of HF and NH4F is used to produce the corresponding structure serving as the die of the micro replication of PDMS. The photoetching technology is left out and the limitation of a photoresist on the dimension of the three-dimensional structure is eliminated; therefore the longer microelectrode array can be made. The length of the microelectrode array depends on the incision depth of the glass and the electroplating technology of deep hole of the metal.

本发明利用玻璃模具、PDMS的微复制特性和电镀技术制作三维微电极阵列，用精密切割机切割玻璃形成柱状阵列，用HF和NH 4 F的混合液腐蚀出相应的结构作为PDMS微复制的模具，免去了光刻工艺，消除了光刻胶对三维结构尺寸的限制，可以制作更大长度的微电极阵列，这一长度决定于玻璃的切割深度和金属的深孔电镀技术。
