  • Publication number: 20200203285
    Abstract: Embodiments of three-dimensional (3D) memory devices and methods for controlling a photoresist (PR) trimming rate in the formation of the 3D memory devices are disclosed. In an example, a method includes forming a dielectric stack over a substrate, measuring a first distance between the first trimming mark and the PR layer along a first direction, and trimming the PR layer along the first direction. The method also includes etching the dielectric stack using the trimmed PR layer as an etch mask to form a staircase, forming a second trimming mark using the first trimming mark as an etch mask, measuring a second distance between the second trimming mark and the trimmed PR layer, comparing the first distance with the second distance to determine a difference between an actual PR trimming rate and an estimated PR trimming rate, and adjusting PR trimming parameters based on the difference.

  • Publication number: 20200185766
    Abstract: The present disclosure relates to an ionic liquid-based quasi-solid-state electrolyte in a lithium battery and a preparation method thereof. The quasi-solid-state electrolyte is of a porous network structure, which is obtained by a condensation reaction of a lithium salt, ionic liquid, a silane coupling agent and a catalyst, and has a high ionic conductivity. The quasi-solid-state electrolyte can stabilize a stripping/deposition process of lithium metal and inhibit growth of lithium dendrites, and shows a low overpotential and long-term cycle stability in a constant current polarization process. The interface impedance of a lithium metal sheet and the quasi-solid-state electrolyte is low, and is hardly increased with the age of the battery.

  • Publication number: 20200116548
    Abstract: The present invention discloses a weighing and measuring system, comprising a weighing sensor network constituted by networking a plurality of weighing sensors, wherein in the weighing sensor network, each of subtasks into which a weighing task is split is assigned to each of weighing sensors in the weighing sensor network; and each of the weighing sensors respectively and independently executes the assigned subtask and exchanges task data through the weighing sensor network. The weighing sensors collaboratively process a weighing task, which no longer depends on an instrument or a computer; thereby reducing the cost of the whole system, and improving the tolerance level to environment. The collaborative processing mode also avoids the bottleneck of data communication information summarization.

  • Patent number: 10547139
    Abstract: An electrical connection device includes an electronic component and a docking component. The electronic component includes a first conductor. The first conductor has a first section and a second section extending forward from the first section. The second section has a contact portion. A width of the contact portion in an extending direction of the second section gradually decreases. The docking component includes a second conductor conductively connected to the first conductor to transmit a high-frequency signal. The contact portion abuts the second conductor. The first section is located behind the second conductor. Thus, the cross-sectional area of the abutting location of the contact portion and the second conductor gradually decreases in the extending direction of the second section. That is, the cross-sectional area of the abutting location of the contact portion and the second conductor gradually decreases relative to the cross-sectional area of the first section.
