    摘要: Embodiments of the present disclosure disclose a backside processing method for a back-illuminated photoelectric device. The backside processing method includes: mechanically thinning the back-illuminated photoelectric device such that a thickness of the back-illuminated photoelectric device reaches a first desired thickness; and chemically thinning and chemically polishing the back side of the mechanically thinned back-illuminated photoelectric device by using a nitric acid solution and a hydrofluoric acid solution such that the thickness of the mechanically thinned back-illuminated photoelectric device reaches a second desired thickness and a surface roughness of the back side of the back-illuminated photoelectric device reaches a desired surface roughness.

    摘要: The present disclosure discloses an afterglow detection device and an afterglow detection method. The afterglow detection device comprises: an X-ray tube for emitting an X-ray beam; a first reading circuit for receiving a first detected signal from a to-be-detected detector to form and output a first measurement signal according to the first detected signal, the to-be-detected detector being connected to the first reading circuit and disposed on a beam-out side of the X-ray tube to receive radiation of the X-ray beam and outputting the first detected signal to the first reading circuit at the time of detection; a residual ray detector disposed on a beam-out side of the X-ray tube; a second reading circuit connected to the residual ray detector for receiving a second detected signal from the residual ray detector to form and output a second measurement signal according to the second detected signal.

    摘要: The present application relates to a dual energy detector and a radiation inspection system. The dual energy detector comprises: a detector module mount and a plurality of detector modules. The detector module includes a higher energy detector array and a lower energy detector array, which are juxtaposedly provided on said detector module mount to be independently irradiated. The present application may simplify the arrangement of the photodiodes and printed circuit boards to which the higher and lower energy detector arrays are connected, such that necessary thickness dimension of the detector module mount is reduced, thereby facilitating the installation and use of the dual energy detector of the present application. On the other hand, the radiation beam in the present application may be independently irradiated to the higher and lower energy detector arrays juxtaposed to each other, which reduces to certain extent the mutual restriction during selection of the higher and lower energy detector arrays.
