[0022] The present invention will be further described below with reference to the drawings and embodiments.
[0023] The cell array chip based on the adjustable micro-magnetic field proposed by the present invention is composed of a base layer, a ground layer, a first insulating layer, a micro-coil array layer, a second insulating layer, a ferromagnetic layer, and a third insulating layer. The first insulating layer, the second insulating layer, the ferromagnetic layer and the third insulating layer are respectively etched with conductive windows; the micro-coil array layer is composed of a micro-coil array and a positive electrode pad, and the micro-coil array shares a positive electrode. The electrode is connected to the ground layer through the conductive window of the first insulating layer; the ferromagnetic layer corresponds to the micro-coil array layer and the coil has an array of through holes, such as figure 1 Shown.
[0024] The preparation process of the above chip is:
