Abstract: A semiconductor device comprises a first doped semiconductor layer, a second doped semiconductor layer, an oxide layer covering the first doped semiconductor layer and the second doped semiconductor layer, and an interconnect. The first doped semiconductor layer is electrically connected with the second doped semiconductor layer by means of the interconnect which crosses over a sidewall of the second doped semiconductor layer. The interconnect comprises a metal filled slit in the oxide layer. At least one electronic component is formed in the first and/or second semiconductor layer. The semiconductor device moreover comprises a passivation layer which covers the first and second doped semiconductor layers and the oxide layer.

Abstract: A pulsed-light detection and ranging apparatus comprises an optical detector arranged to generate, when in use, time-series data in response to an optical pulse incident thereupon. A processing resource is also provided and arranged to support a pulse analyser (132). The pulse analyser (132) is arranged to identify (134) an inflection point of a pulse described by the time-series data. The pulse analyser (132) is further arranged to calculate (138) a distance based upon determined inflection point relative to a time axis associated with the time-series data.

Abstract: A method for noise reduction in an imaging device comprises a 4T pixel in operation, whereby the 4T pixel comprises a pinned photodiode and a floating diffusion node. The method includes the steps of: detecting a signal impinging on the 4T pixel of the imaging device and integrating the charge of the detected signal simultaneously in the photodiode potential well and the potential well of the floating diffusion node; deriving a linear signal proportional to the detected signal from the charge in the photodiode potential well; deriving a compressed signal from the charge in the potential well of the floating diffusion node, while keeping the compressed signal separate from the linear signal, and the compressed signal being a non-linear function of the detected signal; and summing the linear signal and a linearized version of the compressed signal and performing a non-linear conversion on the summation signal to fit the imaging device's output range.
