Problems solved by technology

[0005] However, the position of the laser sensor on the bracket is fixed and has no adjustment function. Affected by the fixed angle of the laser sensor, it has a great influence on the angle of the light emitted by the laser sensor, resulting in poor reliability and versatility of wafer detection.

Abstract

The invention belongs to the technical field of semiconductor processing, and particularly relates to a laser sensor position adjusting device. A first connecting piece of the position adjusting device comprises a first connecting plate and a second connecting plate which are fixedly connected, the first connecting plate is arranged in the first direction and can be movably connected to a carrier in the first direction, the second connecting plate is arranged in the second direction, and the second direction is perpendicular to the first direction; the second connecting piece is fixedly connected with a third connecting plate and a fourth connecting plate, the third connecting plate can swing around a first rotating shaft and is connected to the second connecting plate in a locked mode, the first rotating shaft is arranged in the first direction, the fourth connecting plate is arranged in the third direction, and the third direction is perpendicular to the first direction and the second direction. The laser sensor can swing around a second rotating shaft and is connected to the fourth connecting plate in a locked mode, and the second rotating shaft is arranged in the second direction. The mounting position of the laser sensor on the carrier can be adjusted, so that the use angle of the laser sensor is adjustable, the reliability and the universality of wafer detection are improved, and the practical value is very good.

Description

technical field [0001] The application belongs to the technical field of semiconductor processing, and in particular relates to a laser sensor position adjustment device. Background technique [0002] In the semiconductor industry, the transfer and transfer of wafers in the process chamber are realized by the lifting mechanism and the ejector mechanism. The limit of the ejector mechanism can greatly improve the positioning accuracy of wafer placement and wafer retrieval. [0003] During the wafer transport process, due to control and other reasons, a transfer error may occur, so that it cannot be guaranteed that the wafer can be correctly transferred to the wafer stage inside the reaction chamber, which will seriously affect the subsequent process. And if the wafer transfer is unsuccessful, the wafer is actually still on the manipulator. When the wafer is automatically retrieved after the process is over, an accident that the wafer collides with the thimble will occur, affec...
