Abstract: This disclosure discloses an optical sensing device. The device includes a carrier body; a first light-emitting device disposed on the carrier body; and a light-receiving device including a group III-V semiconductor material disposed on the carrier body, including a light-receiving surface having an area, wherein the light-receiving device is capable of receiving a first received wavelength having a largest external quantum efficiency so the ratio of the largest external quantum efficiency to the area is ?13.

Abstract: Systems and methods of generating a security key for an integrated circuit device include generating a plurality of key bits with a physically unclonable function (PUF) device. The PUF can include a random number generator that can create random bits. The random bits may be stored in a nonvolatile memory. The number of random bits stored in the nonvolatile memory allows for a plurality of challenge and response interactions to obtain a plurality of security keys from the PUF.

Abstract: A self-aligned plug may be formed between deep trench isolation (DTI) etching cycles. Accordingly, etch depth in areas of a pixel sensor with large CDs (e.g., at an X-road) is reduced, which prevents trench loading. As a result, a floating diffusion (FD) region, associated with photodiodes of the pixel sensor, is not damaged during the DTI etching cycles. Reduced chances of damage to the FD region improves performance of the pixel sensor and prevents electrical shorts and failures, which increases yield and conserves time and raw materials used in forming the pixel sensor.

Abstract: A lock mechanism configured to be disposed in an electronic device is provided, including a first lock element, a recovering element, a balancing element, and a second lock element. The first lock element has a lock portion and is disposed in a first body of the electronic device along a moving axis in a sliding manner. The recovering element is disposed between the first lock element and the first body and supplies a recovering force along the moving axis. One side of the balancing element is lodged into the first body, and the other side is lodged into the first lock element. The second lock element is disposed on the second body of the electronic device, and lodged into the lock portion. The balancing element ensures that the first lock element moves smoothly along the moving axis without deviation.
