Abstract: The present invention provides a MEMS structure comprising confined sacrificial oxide layer and a bonded Si layer. Polysilicon stack is used to fill aligned oxide openings and MEMS vias on the sacrificial layer and the bonded Si layer respectively. To increase the design flexibility, some conductive polysilicon layer can be further deployed underneath the bonded Si layer to form the functional sensing electrodes or wiring interconnects. The MEMS structure can be further bonded to a metallic layer on top of the Si layer and the polysilicon stack.

Abstract: A stray-light-coupled biometrics sensing module includes a light-transparent body, a display unit and an optical module. The light-transparent body has a front side and a backside. The front side is configured to support an organic object thereon. The display unit attached to the backside of the light-transparent body displays a frame. The optical module is attached to the backside of the light-transparent body through an adhesive, and is disposed adjacent to the display unit. First light rays of the frame emitted from an eye-viewing screen couple into the organic object through the light-transparent body. After travelling a short distance in the organic object, the first light rays couple out of the organic object and re-enter the light-transparent body as second light rays entering the optical module. The optical module senses the second light rays to generate a biometrics image signal. An electronic apparatus is also disclosed.

Abstract: A portable encrypted storage device with biometric identification includes a host interface connected to a terminal host, a controller connected to the host interface, a memory module, a fingerprint sensor, an encryption/decryption chip and a portable large-capacity storage unit connected to the controller. The controller communicates with the host by handshakes and enables the host to automatically run a fingerprint identification driver and application program from the memory module to the host. The host receives an instruction from the user through the driver and program, and informs the controller to control the fingerprint sensor to read to-be-recognized fingerprint data of the user. The host judges whether or not the to-be-recognized fingerprint data substantially matches with a fingerprint template stored in the memory module. If a match occurs, the host can recognize and access the hidden portable large-capacity storage unit through the encryption/decryption chip.

Abstract: A capacitive sensing array device of an electronic apparatus includes sensing electrodes, a shielding conductor layer, a coupling signal source, a constant voltage source and switch modules. The coupling signal source provides a coupling signal coupled to an object. The constant voltage source provides a constant voltage to the shielding conductor layer to form a stable vertical parasitic capacitor between the shielding conductor layer and each sensing electrode. Each switch module is electrically connected to the constant voltage source via the corresponding sensing electrode. When one sensing electrode is selected to perform sensing, the corresponding switch module is configured as an open-circuited state such that the selected sensing electrode is disconnected from the constant voltage source, while the other sensing electrodes are electrically connected to the constant voltage source to form a stable horizontal parasitic capacitor between the selected sensing electrode and the other sensing electrodes.
