Description
Technical Field
The utility model relates to the technical field of semiconductor equipment heating element materials, in particular to a multi-section heating single-end element base structure.
Background
In the processing and production process of the heating element of the pan-semiconductor equipment, the heating element with a single-end outgoing line with the length of more than 3 meters is needed, and the heating element is needed to heat a semiconductor wafer to the process temperature in vacuum so as to effectively coat the film. The traditional heating element with a single-head outgoing line of more than 3 meters in length is heated in vacuum, the process temperature is high (more than 850 ℃), and the phenomena of poor thermal insulation performance and poor voltage resistance are easy to occur. The heating element with a single-head outlet wire of more than 3 meters in length has short service life and is not in accordance with safety regulations. In addition, in the processing process of the heating element with a single-end outgoing line more than 3 meters in length, because the heating element is long, the processing length of the magnesium rod wound with the resistance wire is only within 500, multiple sections are needed to be spliced, and the traditional multiple sections are spliced to adopt a tripod made of magnesium oxide.
A tripod made of conventional magnesium oxide is mainly used for processing a single magnesium rod, and the magnesium rod spliced by multiple sections cannot be limited and can be ensured to be uniform in insulating layer thickness and loosened. The heating element with a single-end outgoing line of more than 3 meters in length is processed by a tripod made of magnesium oxide, so that the primary failure rate is very high in the production process.
