CARRIER PLATE APPLIED FOR LOAD PORT
A carrier plate applied for a load port is provided, which includes a first guide slot is provided with a first switch to drive a first nozzle to move up and down to switch the position, a second guide slot is provided with a second switch to drive a second nozzle to move up and down to switch the position, a third guide slot is provided with a third switch to drive a third nozzle to move obliquely to switch the position, and a fourth guide slot is provided with a fourth nozzle to move obliquely to switch the position, thereby, the first nozzle, the second nozzle, the third nozzle and the fourth nozzle move to the positions corresponding to the air holes on each of the bottoms of the wafer transfer cassettes to inflate or exhaust the wafer transfer cassette.
HUMIDITY CONTROL DEVICE FOR EQUIPMENT FRONT END MODULE OF SEMICONDUCTOR PROCESSING OR CHARACTERIZATION TOOL
A load port receives a wafer carrier. An equipment front end module (EFEM) transfers semiconductor wafers to and from the wafer carrier via an access opening of a housing of the EFEM, and also transfers wafers to and from a semiconductor processing or characterization tool. A gas flow device disposed inside the housing of the EFEM is connected to receive a low humidity gas having relative humidity of 10% or less, and is positioned to flow the received low humidity gas across the access opening. A saturated pressure layer of the gas flow device has a permeability for the low humidity gas that increases with increasing distance from a gas inlet edge of the saturated pressure layer, for example due to holes of varying diameter and/or density passing through the saturated pressure layer. A filter layer of the gas flow device uniformizes the gas exiting the saturated pressure layer.
FLOW SUPPLY APPARATUS AND SUPPLY METHOD
Provided are a flow supply apparatus and supply method. The flow supply apparatus, comprising: a rail; a transport unit disposed on the rail, where an object is loaded; and a gas treatment unit provided on the transport unit and configured to purge the object. The object includes a FOUP with a substrate accommodated therein, and fume is removed from the substrate through the purging.
SUBSTRATE CARRIER DETERIORATION DETECTION AND REPAIR
A system includes a plurality of semiconductor processing tools; a carrier purge station; a carrier repair station; and an overhead transport (OHT) loop for transporting one or more substrate carriers among the plurality of semiconductor processing tools, the carrier purge station, and the carrier repair station. The carrier purge station is configured to receive a substrate carrier from one of the plurality of semiconductor processing tools, purge the substrate carrier with an inert gas, and determine if the substrate carrier needs repair. The carrier repair station is configured to receive a substrate carrier to be repaired and replace one or more parts in the substrate carrier.
METHODS OF INSTALLING A PURGE FLUID CONDITIONING ELEMENT INTO A SEMICONDUCTOR SUBSTRATE CARRYING CONTAINER
Methods of installing a purge fluid conditioning element into an interior space of a semiconductor substrate carrying container are described. The purge fluid conditioning element is installed from outside the semiconductor substrate carrying container through a port formed in one of the walls of the container, where the port is sized to permit the purge fluid conditioning element to be inserted into the interior space of the container by installing the purge fluid conditioning element through the port. The wall may be a bottom wall of the container or another wall of the container. The described methods eliminate the need to install the purge fluid conditioning element from the inside of the container which can cause human contamination of the interior environment of the container.
ARTICLE STORAGE EQUIPMENT IN SEMICONDUCTOR FABRICATION FACILITY AND LOGISTICS SYSTEM INCLUDING SAME
Proposed are article storage equipment in a semiconductor fabrication facility, the article storage equipment being capable of power supply with a more simplified configuration, and a logistics system of a semiconductor fabrication facility including the same. Article storage equipment in a semiconductor fabrication facility according to one aspect includes a storage unit installed around a rail that provides a travel route of a transport vehicle and configured to store a transport container in which a wafer is accommodated, a purge unit configured to supply an inert gas into the transport container, a control unit configured to identify the transport container stored in the storage unit and control the purge unit to supply the inert gas into the transport container, and a power supply unit configured to supply a current induced from a power supply cable installed along the rail to the control unit.
Method and system for naturally oxidizing a substrate
A system and method for treating a substrate in a reaction chamber. A transfer chamber is arranged between a first lock and a second lock, wherein the second lock is provided between the transfer chamber and the reaction chamber. A substrate is transferred into the transfer chamber through the first lock, and the first lock is closed. In a next step, the transfer chamber is flooded with the same gas as in the reaction chamber and the pressure and temperature of the gaseous atmosphere in the transfer chamber is controlled to be the same as in the reaction chamber. Then, the second lock is opened and the substrate is transferred from the transfer chamber into the reaction chamber to treat the substrate. A computer program product for carrying out the above method.
Mechanisms for charging gas into cassette pod
Embodiments of mechanisms for charging a gas into a cassette pod are provided. A method for charging a gas into a cassette pod includes loading at least one semiconductor wafer into a housing of the cassette pod after the at least one semiconductor wafer is processed by a processing apparatus. The method also includes removing the cassette pod from the processing apparatus by a transporting apparatus to a predetermined destination. The method further includes charging a gas into an enclosure in the housing of the cassette pod from a gas supply assembly disposed on the housing.
System and Method for Cleaning Carrier
This invention provides a method and a system for cleaning a container for storing wafers or masks. A contained with lid is washed directly after the container is loaded with lid opened in the cleaning system. Gas exchange rate in the washing station can be increased such that particles or AMC inside the container or attached to the lid can be carried out more easily. Then, contamination-free gas is purged to the container as well as lid in a high temperature environment. A vacuum station can be optionally adapted between the washing station and the contamination-free gas purging station to enhance the cleanliness of the container.
Method of manufacturing semiconductor device
To protect a plurality of semiconductor chips of a sawn wafer housed in a shipping case and a method of manufacturing a semiconductor device includes a step of vacuum packing a sawn wafer while being housed in a shipping case; the shipping case has the following structure: the shipping case has a lid portion that covers the upper surface of the sawn wafer and a body portion that covers the lower surface of the sawn wafer, the lid portion has a recess portion that covers a plurality of semiconductor chips and a ventilation route communicated with the recess portion. In a step of reducing pressure in the shipping case, a gas in the shipping case is discharged outside via a ventilation route.
