The embodiments of the present application provide a method for manufacturing a semiconductor structure, comprising: successively forming a target layer, a first mask layer, an isolation layer and an intermediate layer on a substrate, the intermediate layer in a first zone having at least one first recess, and the intermediate layer in a second zone having at least one second recess; forming filling layers, the filling layers filling the first recess and the second recess, the upper surfaces of the filling layers being higher than the upper surface of the intermediate layer, and the height difference between the top surface of the filling layer on the first zone and the top surface of the filling layer on the second zone being less than or equal to a first preset value; performing a maskless dry etching process to remove a part of the filling layer on the first zone until the top surface of a sacrificial layer is exposed; removing the sacrificial layer covering a side wall of the first recess so as to form a first opening on the first zone; and etching a part of the target layer by using the first opening, the remaining target layer constituting a target pattern. The embodiments of the present application are conducive to completely etching a target layer to form a required target pattern.

This utility model relates to the field of machining technology, specifically to a uniform grinding device for needle production. It includes an operating table, with a clamping drive platform fixedly connected to its upper surface. Two adjusting plates are slidably connected to the side of the operating table near the clamping drive platform. Grinding rollers are rotatably connected to the inner walls of both adjusting plates. Cleaning devices are provided on the sides of the two adjusting plates that are far apart from each other. Each cleaning device includes two L-shaped plates, fixedly connected to the sides of the two adjusting plates that are far apart from each other. Scrapers are fixedly connected to the sides of the two L-shaped plates near the adjusting plates, and the scrapers abut against the grinding rollers. This utility model solves the problem that when using grinding rollers to grind needles, the surface of the grinding rollers is easily affected by residual needle debris, thus affecting the uniformity and efficiency of the grinding process.

The application discloses an air inlet pipe rubber joint processing die and method, and the die comprises an upper die, a lower die, a die core and a framework, the upper die, the lower die and the die core jointly form a cavity accommodating rubber, the framework is arranged in the cavity, the lower die is provided with a positioning hole, the die core is provided with a positioning protrusion matched with the positioning hole, and the die core is coaxially arranged with the cavity through the positioning protrusion; the die further comprises an injection cylinder and a cylinder cover, the injection cylinder is arranged on the upper die, the injection cylinder is provided with an accommodating cavity accommodating rubber and an injection opening for injecting rubber into the cavity; the cylinder cover is arranged on the injection cylinder and is provided with an abutting part matched with the accommodating cavity, and the cylinder cover moves towards the injection cylinder under the driving of external force, so that the rubber in the accommodating cavity is extruded into the cavity through the injection opening; the connecting parts of the lower die and the upper die, the upper die and the injection cylinder and the die core and the injection cylinder are all provided with material returning grooves near one end of the cavity, so that the problems of burrs and deformation of the plastic framework in the traditional process are effectively solved.

This invention relates to the field of computer system technology based on specific computational models, and discloses a screening system and method for tumor therapeutic drugs, comprising: a modality-specific tokenization engine for generating a first token for data content and a quality characterization token for data credibility; a dynamic sequence assembly module for assembling the first token and the quality characterization token for available modalities; and a sequence fusion Transformer module for collaboratively processing the assembled token sequence and adjusting the dependence on the first token according to the quality characterization token, and finally generating a prediction output. This invention solves the technical problem that specific computational models cannot perceive quality differences when processing data uniformly. By enabling the model to simultaneously know the data content and data credibility during fusion, it achieves autonomous distrust of low-quality data input by the model, avoiding the drowning out of key signals by noisy data.
