Abstract
A chemical vapor deposition device capable of reciprocating rotation and lifting is provided. The chemical vapor deposition device includes a cavity, a base, a fixing bracket, a lifting mechanism, and a rotation mechanism. The present disclosure utilizes the principle of magnetic-fluid sealing to achieve device sealing and integrates the rotation and lifting functions, satisfying the coordinated work of reciprocating rotation, lifting movement, wafer heating, etc. at the same time without affecting each other. Moreover, the problem of physical entanglement and damage of electrical wires during the rotation process has been avoided, and micro-particles formed in the cavity will not affect the rotation mechanism, thereby enabling the efficient and stable operation of the rotation mechanism. The present disclosure has fewer transmission components, which reduces instability and mechanical wear caused by redundant components, improves the accuracy and stability of lifting and rotation control, and minimizes manufacturing costs and power consumption.
