Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of vapor deposition equipment, and in particular relates to a plasma chemical vapor deposition device. Background Art
[0002] Chemical vapor deposition (CVD) is a semiconductor process for manufacturing thin films. Traditional chemical vapor deposition equipment usually includes a horizontally placed carrier and a gas supply head located above the carrier. The gas supply head provides reaction gas to one or more objects carried on the carrier. After the reaction gas reacts with the object, the desired thin film is formed on the object. Compared with coating and lamination, this process is simpler, not easy to break the film, the product only needs sampling quality inspection, and is suitable for seals of various complex shapes.
[0003] When the existing chemical vapor deposition device performs chemical vapor deposition on an object, the gas supply head needs to maintain a certain distance from the carrier and spray the reaction gas toward the carrier. However, when the gas supply head sprays the reaction gas to the object, part of the reaction gas that performs chemical vapor deposition on the edge of the object will diffuse to the surrounding side of the object, resulting in a significant difference in the deposition effect at the center of the object and the deposition effect at the edge of the object, which reduces the uniformity of the chemical vapor deposition of the object and further reduces the quality of the object's work.
[0004] Before coating the material, the object needs to be clamped and fixed to expose the position where the coating is required, so as to improve the coating effect of the seal and improve the production efficiency of the seal. In traditional devices, when the coated parts are fixed and placed, the coating parts often fall off from the clamping structure due to insufficient suction, reducing work efficiency.
[0005] Therefore, in order to solve the problem of uneven chemical vapor deposition caused by uneven placement and falling of objects in traditional technologies, a plasma chemical vapor deposition device is urgently needed to solve the existing problems. Summary of the invention
[0006] In view of this, the present invention aims at the deficiencies of the prior art and provides a plasma chemical vapor deposition device, which can not only solve the problems of uneven placement and falling objects in traditional technology and improve work quality, but also ensure the uniformity of the coating when chemical vapor deposition is performed on the objects.
