This invention relates to the field of dispensing equipment technology, and discloses a dispensing method and dispensing equipment. The dispensing method includes the following steps: adding 10% of a preset mass of material based on an initial density, and weighing it to obtain the actual density of the material; continuing to add material based on the actual density until the added mass reaches 90% of the preset mass; and continuing to add material through closed-loop control until the difference between the added mass and the preset mass is less than or equal to the dispensing error. The dispensing method and equipment of this invention offer high dispensing accuracy, short dispensing time, and can automatically, precisely, and quickly complete the addition of raw materials to the formula, significantly saving dispensing time and accelerating material development progress.

This utility model relates to an electrolyzer device and hydrogen production equipment, which includes a support assembly, an electrolyzer assembly, and a hydraulic assembly. The electrolyzer assembly includes multiple electrolysis chambers arranged sequentially along a first direction, and each electrolysis chamber is slidably connected to the support assembly; the power output end of the hydraulic assembly is fixedly connected to one end of the electrolyzer assembly; and the hydraulic assembly can drive the electrolysis chambers to move along the first direction. In the above-mentioned electrolyzer device and hydrogen production equipment, since the power output end of the hydraulic assembly is fixedly connected to one end of the electrolyzer assembly, the movement of the electrolysis chambers along the first direction can be achieved by driving the hydraulic assembly, thereby changing the distance between the multiple electrolysis chambers, thus realizing the rapid sealing or disassembly of the electrolyzers, making the disassembly and assembly efficiency of the entire electrolyzer high, thereby improving the development progress of the electrolyzer and meeting the needs for rapid testing, rapid iteration, rapid development and market launch of new materials and new products.

This application relates to a parameter calibration method and manufacturing method for a semiconductor device, comprising: acquiring a simulation model corresponding to the semiconductor device; calibrating the simulation model according to a parameter database of the semiconductor device, wherein the parameter database includes at least ion concentration distribution data and electrical data corresponding to different active region widths of the semiconductor device; testing the calibrated simulation model, and acquiring electric field distribution information and ion concentration distribution information at the corners of the shallow trench isolation structure in the simulation model; if an anomaly is determined to occur at the corner based on the electric field distribution information and ion concentration distribution information, adjusting the process parameters at the corner, and retesting the simulation model obtained after adjusting the process parameters until no anomaly occurs at the corners of the simulation model; and outputting the process parameters corresponding to the current simulation model if no anomaly occurs at the corners. This application improves the R&D progress and saves evaluation and production costs.
