Title: Substrate treatment device
Inventor: YAMAZAKI TATSUYA
IPC: H01L21/285
Filed: 1990-07-25
Abstract: PURPOSE:To enable forming an ultra-high vacuum with a good thermal efficiency and without polluting the atmosphere in a reactor by arranging an escape gas-preventing member, which separates a heating member from the atmosphere in the reactor, between the heating member and a substrate and by heating the substrate via the escape gas-preventing member. CONSTITUTION:Around a carbon heater 3, a quartz cover 4 is arranged into a structure surrounding this carbon heater 3 and an Si wafer 2 is arranged on the quartz cover. Therefore, the Si wafer 2 is heated by the carbon heater 3 via the quartz cover 4. Into a reactor, SiH4, etc., are introduced as a reaction gas by a reaction gas introduction pump, etc. That is, an escape gas is intercepted by the quartz cover 4 so that the escape gas does not enter the atmosphere of the reactor 1 and the degree of ultrahigh vacuum is maintained in the reactor 1. The quartz cover is used as an escape gas-preventing member, because the escape gas-preventing member must pass a radiation heat from the carbon heater 3 but the Si wafer 2 is heated by such radiation heat and because quartz is suitable as such member also from its low cost.
