Abstract: A MEMS package includes a first board, a second board and a laminate material. The first board includes a lower metallic trace, a metallic diaphragm and a through opening. The lower metallic trace is located on the lower surface of the first board, and the metallic diaphragm is disposed on the lower metallic trace. The second board includes an upper metallic trace and a metallic electrode. The upper metallic trace is located on the upper surface of the second board, the metallic electrode is disposed on the upper metallic trace, and the metallic electrode is corresponding to the metallic diaphragm. The laminate material is disposed between the lower and upper metallic traces, and includes a hollow portion for accommodating the metallic electrode and metallic diaphragm, wherein a sensing unit is formed by the metallic electrode, the hollow portion and the metallic diaphragm, and is corresponding to the through opening.

Abstract: A singulation method used in a process for making a plurality of image sensor packages is disclosed. Firstly, a semi-finished product including a plurality of package structures formed on a substrate is placed on a support having a plurality of cavities for receiving the package structures. Then, the semi-finished product is sawed into separate image sensor packages. During the sawing step, the air pressure in the cavities is decreased to create suction within the cavities such that the support abuts against at least a portion of the housing of each package structure with a gap between the transparent component and the support whereby the package structures are positioned precisely and clamped in place with the support during the sawing step.
