  • Patent number: 12344936
    Abstract: Provided is a method of supplying a liquid raw material to a gas supply device. The gas supply device includes: a storage tank that stores the liquid raw material; a heating unit that heats the liquid raw material to generate a raw material gas; a level detecting unit that detects a liquid surface level of the liquid raw material stored in the storage tank; a gas inlet and a gas outlet provided in the storage tank; and a raw material inlet provided in the storage tank. The method includes: determining whether the liquid surface level of the liquid raw material is equal to or lower than a supply target level; and repeating supply of a specified amount of liquid raw material to the storage tank a specified number of times when the liquid surface level of the liquid raw material is equal to or lower than the supply target level.

  • Patent number: 11621185
    Abstract: A semiconductor manufacturing apparatus includes one or more process modules, a scheduler, and a transfer controller. A product wafer of a lot that is transferred from a load port to one of the one or more process modules is replenished such that a total number of wafers that are simultaneously processed in the one or more process modules becomes N. When an advance lot being processed and a post lot to be processed subsequent to the advance lot have a same processing condition, the scheduler creates the transfer plan to replenish with the product wafer of the post lot instead of a dummy wafer such that the transfer controller transfers the product wafer and the dummy wafer to the one or more process modules according to the created transfer plan.

  • Patent number: 9766617
    Abstract: The substrate processing apparatus includes: a plurality of processing modules; a transfer mechanism; a controller; and a setting unit. The processing module processes with respect to the substrate. The transfer mechanism transfers the substrate ejected from the transfer container. The controller outputs control signals for transferring the substrate to the plurality of processing modules along a previously set transfer path through the transfer mechanism sequentially, and for processing with respect to the substrate in the processing module of a transfer destination based on a processing recipe in which a processing order and a processing condition are set. The setting unit sets a content of a non-recipe operation except for operations set in the processing recipe and a performing timing for performing the non-recipe operation by a control operation of the controller every processing module. The non-recipe operation is performed with respect to the processing modules.
