The present application relates to a method for preparing a semiconductor device, which includes: providing a target to be etched; sequentially forming a first mask layer, a first anti-reflection layer and a second mask layer on the surface of the target to be etched; In the reaction gas, the second anti-reflection layer is formed on the surface of the second mask layer; the photoresist mask pattern is formed on the surface of the second anti-reflection layer; A first reticle pattern is formed on the first anti-reflection layer; a dielectric layer is formed on the first anti-reflection layer and the first reticle pattern; other parts of the first anti-reflection layer except the sidewall are etched, to form a second intermediate mask pattern; using the second intermediate mask pattern as an etching mask, etching the first anti-reflection layer and the first mask layer to form a target pattern on the target to be etched. Such a design can alleviate the phenomenon of low film retention of the photoresist and the second anti-reflection layer, and ensure the good rate in the fabrication process of the semiconductor device.

Provided are a clamping system and method for finish machining of large workpieces. The clamping system comprises a clamping disk which is provided with a plurality of dovetail clamping grooves radiated to the outside from the center of the disk; a rotating clamping block capable of performing sliding and fixing along the corresponding dovetail clamping groove is arranged in each dovetail clampinggroove, and therefore due to sliding and fixing of the plurality of rotating clamping blocks, the large workpieces in various shapes are clamped; each rotating clamping block is driven through a micro motor, each micro motor is connected to the bottom of the corresponding rotating clamping block through a ball screw structure, and therefore sliding and fixing of the rotating clamping blocks in the dovetail clamping grooves are achieved, and each rotating clamping block is provided with a force sensor; and thus, the clamping system and method for finish machining of the large workpieces can guarantee workpiece clamping during finish machining, and guarantee the excellent rate of the workpieces after machining.

The invention provides a design method for a printing ink hole plugging tool. The design method comprises the steps that a base plate is placed on a PCB, an inverted-cone-shaped hole is formed in the base plate, the position of the inverted-cone-shaped hole is matched with that of a plug hole formed in the PCB, the size of the lower surface of the inverted-cone-shaped hole is matched with that of the plug hole, the axial section of the inverted-cone-shaped hole has the inclination degree, and therefore printing ink can be subjected to pushing force applying into the inverted-cone-shaped hole when squeegee is screen-printed to the inverted-cone-shaped hole. According to the design method, the hole plugging force is increased, the hole plugging fullness can be effectively guaranteed, the product quality is improved, and the good rate of finished products is guaranteed; the stressed area of the squeegee is increased, the hole plugging efficiency is effectively improved, and the hole plugging time is shortened.
