Abstract

The invention discloses a position calibration device for a wafer box. The position calibration device comprises a supporting plate assembly, an adjusting mechanism and a detection mechanism; the supporting plate assembly is connected with the adjusting mechanism and is used for bearing the wafer box; the detection mechanism is used for detecting the actual position of the wafer box; and the adjusting mechanism is used for driving the wafer box to perform deflection motion and/or translational motion on the supporting plate assembly under the condition that the detection mechanism detects that the actual position is not at the preset position, so that the wafer box moves to the preset position from the actual position. Accurate positioning of the wafer box can be achieved, so that the accuracy of a wafer taking position is guaranteed, and wafer taking failure or wafer collision of a mechanical arm and other abnormalities are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a position calibration device for a chip box. Background technique [0002] Cassette position calibration equipment is widely used in the field of semiconductor technology. For example, when performing silicon sampling, it is necessary to place the cassette on the position calibration equipment to adjust the levelness, and then operate the manipulator to take out the silicon wafer from the cassette. [0003] However, in the current casket position calibration equipment, the calibration operation is performed before sampling. If the position of the cassette is deviated during the sampling process, it is necessary to manually pause and re-adjust, which will affect production efficiency. If the deviation is not detected If it is discovered in time, it may cause the failure of picking up the wafer or the collision of the manipulator, resulting in damage to the silicon wafer or...
