摘要:
A semiconductor device producing apparatus is disclosed. The apparatus includes a carrier-holding stage for placing a carrier; first, second and third stages each for holding first and second boats one at a time, each boat holding one or more substrates; a boat transfer mechanism for transferring the boats among the first, second and third stages; and a substrate transfer mechanism for transferring the substrate(s) from the carrier to the boat held by the first stage. A controller controls the first stage, the boat transfer mechanism and the substrate transfer mechanism so that the boat transfer mechanism transfers one of the boats from the second stage to the first stage, the substrate transfer mechanism then transfers the substrate(s) from the carrier to the boat held by the first stage, and the first stage then moves the boat into the processing chamber for processing.

A substrate processing equipment comprises two pod supporting stages and two independently operable pod door openers. Each pod supporting stage is capable of placing thereon a pod for containing substrates therein. Each pod door openers having means for permitting access to the substrates inside the pod placed on a corresponding pod supporting stage.
摘要:
A substrate processing apparatus includes a housing, a process tube for performing variable batch processes on substrates, and product substrate carriers. The product substrate carriers have a capacity of a predetermined number of substrates. A number of the product substrates processed during one batch process are less than or equal to the predetermined number of the substrates. All of the product substrates contained in one product substrate carrier is processed in the process tube at a same time.

Substrate positioning and substrate transporting are processed in parallel, thereby reducing substrate transfer apparatus wait time and improving substrate processing throughput. A substrate transfer apparatus 1 is configured in a single unit, a plural number of wafers W prior to notch alignment is transported at one time from a substrate accommodating container to a substrate alignment apparatus 22, and the plural number of notch aligned wafers is transported from the substrate alignment apparatus 22 to a boat 21. Two stages (upper and lower) of notch alignment units 4 and 5 that configure the substrate alignment apparatus 22 operate independently, and are capable of performing notch alignment, in total, on a number of wafers to be processed that is twice the number of wafers transported at one time by the substrate transfer apparatus 1. While notch alignment is being performed in the one notch alignment unit 4, notch aligned wafers W are transported by the substrate transfer apparatus from the other notch alignment unit 5 to the boat 21, and then wafers prior to notch alignment are transported from the substrate accommodating container to the other notch alignment unit 5.
摘要:
A substrate processing apparatus includes a process tube for processing a plurality of substrates, two boats for accommodating the substrates, two boat elevators, a substrate transfer unit for loading and unloading the substrates into and from the boats when the boats are at the first position. In this apparatus, each boat elevator has one boat mounted thereon and each of the boat elevators carries a corresponding boat between a first position located below the process tube and two corresponding second positions. Each of the boat elevators performs loading and unloading the corresponding boat into and from the process tube at the first position. Further, in the apparatus, a center position of the process tube is disposed inside a triangle formed by connecting the substrate transfer unit and the two boat elevators.
摘要:
A heat treatment apparatus includes a vertically disposed process tube defining a reaction chamber therein; a main heater for heating the reaction chamber, the main heater being disposed outside of the process tube; a boat for holding a plurality of wafers, the boat being loaded into and unloaded from the reaction chamber; and a boat rotating device for rotating the boat. The boat rotating device is provided with a rotatable hollow shaft assembly and a fixed shaft coaxially disposed inside the rotatable hollow shaft assembly. A sub-heater is attached to an upper end of the fixed shaft, and the boat and an insulating portion are disposed on the rotatable hollow shaft assembly.
摘要:
Software and hardware such as part feeding and assembling devices constituting a production system are simplified with the use of a plurality of processing and assembly integrated units in which processing and assembling of parts are coupled and integrated in accordance with products to be produced. The necessities for an automatic warehouse and an automated ground vehicle are eliminated by getting rid of futility of mere movements of the parts. A fundamental idea is that a production system is constructed of units in which three sections--a section for processing a raw material, a check functional section and an assembling section--are integrally combined in accordance with the products to be produced. The parts are processed, checked and assembled by single units just in time while targeting molded parts of plastic and pressed parts.
