Abstract:
PURPOSE: A semiconductor device and a manufacturing method thereof are provided to facilitate connection between semiconductor devices of an SiP(Silicon in Package) by connecting external electrodes with the shortest distance using a through-via. CONSTITUTION: A semiconductor substrate(1) is provided. At least one inter-metal dielectric(3,5) is formed on the semiconductor substrate. A circuit part is formed in the semiconductor substrate and the inter-metal dielectric. A metal layer(9) is formed in an upper side of the inter-metal-dielectric to connect the circuit part with an external electric signal. A passivation layer is formed on the metal layer. A hole is formed in the passivation layer to expose a part of the metal layer. The hole is formed to pass through the exposed metal layer, the inter-metal-dielectric, and the semiconductor substrate successively. A first external electrode(31) and a through via(19) are formed by burying the conductive material in the hole. A semiconductor substrate is polished to form a second external electrode(33) by the exposure of the through via by passing the end of the through via through the bottom of the semiconductor substrate.
Abstract:
Provided in the present invention is a MEMS package including a capping member which has a thin portion to provide a cavity having light transmittance and a deep depth useful to vacuum form and maintain, which has a thick portion useful to provide easy handling. According to an embodiment of the present invention, the MEMS package includes: a capping member including a basal portion, a window portion recessed from the top surface of the basal portion and a protrusion portion protruded from the top surface of the basal portion while surrounding the window portion; and a MEMS element member including a MEMS substrate attached with the capping member, and a MEMS element covered by the window portion while being surrounded by the protrusion portion.
Abstract:
PURPOSE: An apparatus for authenticating a user by using a security tag storing biometric information and a method thereof are provided to implement the security tag to which a lenticular film is attached, thereby preventing the illegal forgery and alteration of the security tag. CONSTITUTION: A security tag (110) stores the encrypted biometric information of a user. A photographing unit (211) provides a first image and a second image. The first image is generated by photographing the security tag in a first position according to the authentication request of the user. The second image is generated by photographing the security tag in a second position symmetrical to the first position. A data recovery unit (212) recovers the encrypted biometric information from the images. A personal information input unit (220) scans and reads the real biometric information of the user. A biometric information matching unit (230) determines whether the recovered biometric information is coincident with the real biometric information, and accepts or rejects the authentication request of the user.
