Abstract: In one example, an electronic device comprises a lower substrate comprising a lower dielectric structure and a lower conductive structure, an electronic component coupled with a bottom side of the lower substrate and coupled with the lower conductive structure, an upper substrate over a top side of the lower substrate and comprising an upper dielectric structure and an upper conductive structure, an internal interconnect between the upper substrate and the lower substrate and coupled with the upper conductive structure and the lower conductive structure, and a first antenna component between the upper substrate and the lower substrate and coupled with the upper conductive structure. Other examples and related methods are also disclosed herein.

Abstract: Disclosed herein are a method and an apparatus to identify alpha-emitting radionuclides and to measure absolute alpha radioactivity using a low temperature detector. A 4? metallic absorber which encloses a radioactive material containing alpha-emitting radionuclides absorbs the total alpha decay energy in the form of thermal energy. The corresponding temperature changes are measured by a low temperature detector attached to the 4? absorber with high energy resolution. The identification of alpha-emitting radionuclides is declared by comparing the measured temperature signal with characteristic decay energy of radionuclides. The absolute amount of the radionuclides is determined by counting the number of the pulses for each of the identified nuclides.

Abstract: Disclosed herein is an absorber with a hole for a metallic magnetic cryogenic detector and an aligning method. More specifically, the present invention is to provide an absorber with a small hole as an aligning mark for a temperature sensor used in a metallic magnetic cryogenic detector. A temperature sensor is bonded on the small hole of the absorber punched by a laser. Using the hole as an aligning mark the temperature sensor can be accurately positioned on the pick-up coil of the measuring means. Thus, the aligning method provides a magnetic measurement with an ideal coupling between the sensor and the pick-up loop. It eventually presents a precise measurement of the energy spectrum absorbed in a metallic magnetic cryogenic detector.
