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.
