Abstract: A method for profit sharing is provided. The method includes deciding a first sharing rate according to a first event information and a first category information; obtaining a first sharing amount according to the first sharing rate and a first shared profit of the first category information; deciding a second sharing rate according to a second event information and a second category information; obtaining a second sharing amount according to the second sharing rate and a second shared profit of the second category information; deciding a total sharing amount by summing up the first sharing amount and the second sharing amount; and returning the total sharing amount in response to receiving a request from a user device.

Abstract: A method for determining integrity of information of an object, comprises generating a first data corresponding to the information of the object and generating a first representative data corresponding to the first data; storing the first data to a database, and adding the first representative data into a first block of a blockchain; reading a second data from the database in response to a command for retrieving the first data from the database; using the first block to indicate whether the second data is identical to the first data.

Abstract: A method of item management, comprises establishing a blockchain network comprising at least a wallet, which is corresponding to at least a container; issuing a first token corresponding to a plurality of items to a first wallet of the at least a wallet in the blockchain network when the plurality of items is added to a first container of the at least a container; and modifying a status of the first token according to a status of the plurality of items in the first container.

Abstract: The present invention discloses a slotted retaining ring for use in a chemical mechanical polishing head which can be fabricated by providing a plurality of slot recesses in a bottom surface of the retaining ring. Each of the plurality of slot recesses may be formed in a tapered shape with a base portion adjacent to the outer periphery of the ring and a tip portion of a smaller width than the base portion adjacent to the inner periphery of the retaining ring. The tip portion of the tapered shape is normally spaced apart from the inner periphery such that excessive polishing of the wafer edge can be avoided. The present invention further discloses a method for chemical mechanical polishing a semiconductor wafer by using the slotted retaining ring for holding a polishing head therein.

Abstract: An apparatus for cleaning a process chamber that includes a ventilation hood which has a fluid flow channel attached to an inner peripheral wall of the hood body equipped with a plurality of fluid nozzles pointing downwardly toward a process chamber cavity when the hood is positioned on such process chamber, and a method for using the apparatus. A purge gas flown through the fluid nozzles carries substantially all contaminating fumes or particles away from the process chamber cavity into an air evacuation system such as a factory vacuum exhaust system such that contamination of the process chamber can be essentially eliminated.
