Claim:
1. A micro-electro-mechanical system (MEMS) device, comprising: a substrate; a proof mass, including at least two slots, each of the slots including a first inner space and an opening, wherein the first inner space is relatively closer to a center area of the proof mass than the opening; at least two anchors, respectively located in the corresponding first inner spaces and connected to the substrate; at least two linkages, respectively located in the corresponding slots and connected to the corresponding anchors; and a multi-dimensional spring structure for assisting a multi-dimensional movement of the proof mass, the multi-dimensional spring structure surrounding a periphery of the proof mass, and connected to the substrate through the linkages and the anchors, the multi-dimensional spring structure comprising: an outer frame which is connected to the first and second springs and forms a frame-like structure which encompasses all of the proof mass, wherein the second springs are connected to the proof mass through the first springs.
