Abstract: A gate-last ferroelectric field effect transistor includes a substrate, isolation regions, a gate structure, a side wall spacer, source and drain regions, a first metal silicide layer and an interlayer dielectric layer which are sequentially arranged from bottom to top; the present disclosure further provides a manufacturing method of a gate-last ferroelectric field effect transistor; according to structural characteristics of the gate-last ferroelectric field effect transistor and crystalline characteristics of a hafnium oxide-based ferroelectric film, a dummy gate is first introduced in a manufacturing process of the gate-last ferroelectric field effect transistor; afterwards, high-temperature annealing is performed to make sure that an unannealed hafnium oxide-based film is crystallized to form a ferroelectric phase; finally the dummy gate is removed and a gate electrode layer is deposited to meet performance requirements of the gate-last ferroelectric field effect transistor; and the gate-last ferroelectr

Abstract: Embodiments of three-dimensional (3D) memory devices and methods for forming the same are disclosed. In an example, a 3D memory device includes a substrate, a memory stack on the substrate, a plurality of channel structures each extending vertically through the memory stack, and one or more isolation structures. The memory stack includes a plurality of interleaved conductive layers and dielectric layers. An outmost one of the conductive layers toward the substrate is a source select gate line (SSG). Each isolation structure surrounds at least one of the channel structures in a plan view to separate the SSG and the at least one channel structure.

Abstract: A conveying device (100) and an inspection system (1000) are provided. The conveying device includes: a first support frame (1); a first conveying mechanism (2) and a second conveying mechanism (3) which are installed on the first support frame; and a switching mechanism (4) configured to selectively lift the first conveying mechanism or the second conveying mechanism in a vertical direction, such that the first conveying mechanism or the second conveying mechanism carries goods (401) and conveys the goods in a first horizontal direction or a second horizontal direction different from the first horizontal direction. The conveying device may achieve a positioning and a smooth continuous conveying of goods, and achieve a smooth conveying and a calibrated positioning of the goods in different postures.

Abstract: Methods are presented for tuning the time-domain emissive profile of single upconversion nanoparticles using a number of different techniques so as to increase the coding capacity at the nanoscale. The disclosure also relates to time-resolved wide-field imaging and deep-learning techniques to decode the nanoparticle fingerprints.
