Problems solved by technology

The shortcomings of the existing equipment are: 1. A set of equipment can only operate on one size of wafer, and the wafer size is not compatible, resulting in high production costs; 2. The pre-printed label is pasted on the wafer, It is impossible to temporarily change the label, and the automation rate of label affixing is low; 3. The wafer loading and unloading is operated separately, resulting in low processing efficiency; 4. The wafer is small in size and inconvenient for clamping and positioning, resulting in low processing efficiency and yield

Abstract

The invention relates to the technical field of integrated circuits. A wafer fixing device comprising a wafer adsorption mechanism and a wafer stage mechanism. The wafer stage mechanism is used for receiving the processed wafer. The wafer suction mechanism is located in the center of the wafer stage mechanism for sucking the wafer fixed on the wafer stage mechanism. The wafer fixing device has theadvantages of convenient and stable wafer positioning, and is suitable for wafers of different sizes.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to wafer labeling equipment. Background technique [0002] Wafer refers to the silicon wafer used in the production of silicon semiconductor integrated circuits. Millions of transistors can be etched on the wafer through a special process, and it is widely used in the manufacture of integrated circuits. After the wafer processing is completed, a label needs to be attached to it. The existing labeling operation method is: first fix the wafer, then paste the pre-printed label on the wafer, remove the labeled wafer and continue Load the wafers to be labeled and repeat. The shortcomings of the existing equipment are: 1. A set of equipment can only operate on one size of wafer, and the wafer size is not compatible, resulting in high production costs; 2. The pre-printed label is pasted on the wafer, It is impossible to temporarily change the label, and the automation rate of...
