Abstract

The invention discloses a heating device for a plasma processing semiconductor manufacturing device. The heating device comprises: at least one heating wire extending within coverage of a radio frequency signal; a power supply providing an electrical signal to the at least one heating wire; and a temperature controller controlling the power supply based at least on a default temperature supplier. The at least one heating wire is covered by at least one shielding component for shielding the radio frequency signal and preventing the radio frequency signal from being electrically coupled to the at least one heating wire, the power supply and the temperature controller.

Description

technical field [0001] The present invention relates to a heating device, especially for a semiconductor manufacturing device for plasma processing, such as a heating device installed in a showerhead or a substrate support. Background technique [0002] In semiconductor manufacturing technology, it is known that increasing the temperature of the reacting substance or the environment can obtain a more ideal morphology of the deposited film, especially when the temperature is raised to 200° C., it is helpful for the reaction of the substance. There are known oil temperature heaters used in shower heads, but limited by the characteristics of oil, such heaters cannot be raised above 200°C, which cannot meet the requirements of the process. [0003] Electric heaters have been used to solve the lack of oil temperature heaters, but there are still concerns about the performance of electric heaters for specific treatments. In semiconductor manufacturing equipment dedicated to plasm...
