Abstract: Structures with doping free connections and methods of fabrication are provided. An exemplary structure includes a substrate; a first region of a first conductivity type formed in the substrate; an overlying layer located over the substrate; a well region of a second conductivity type formed in the overlying layer; a conductive plug laterally adjacent to the well region and extending through the overlying layer to electrically contact with the first region; and a passivation layer located between the conductive plug and the well region.

Abstract: Various embodiments of the present disclosure are directed towards a stacked complementary metal-oxide semiconductor (CMOS) image sensor in which a pixel sensor spans multiple integrated circuit (IC) chips and is devoid of a shallow trench isolation (STI) structure at a photodetector of the pixel sensor. The photodetector and a first transistor form a first portion of the pixel sensor at a first IC chip. A plurality of second transistors forms a second portion of the pixel sensor at a second IC chip. By omitting the STI structure at the photodetector, a doped well surrounding and demarcating the pixel sensor may have a lesser width than it would otherwise have. Hence, the doped well may consume less area of the photodetector. This, in turn, allows enhanced scaling down of the pixel sensor.

Abstract: An asset right management system based on blockchain and a method thereof are disclosed. In the system, an asset smart contract of the asset is pre-deployed on a blockchain network, and an asset smart contract is executed to generate a fungible ownership token representing the ownership of the asset, and generate a non-fungible use-right token representing the right to use the asset, based on the ownership token; when the asset smart contract receives proceeds which is obtained through a transaction of the use-right token, the asset smart contract calculates and transfers an profit-sharing amount of each owner, so as to achieve the technical effect of improving convenience in rights management and income of the asset.

Abstract: An initial issuance and secondary delivery system for a NFT and an entity of a virtual-real coupling product and a method thereof. In the system, a NFT smart contract is deployed on a blockchain network, and a product NFT is generated before or while an initial register function of the NFT smart contract is executed, and the initial register function is permitted to transfer an ownership of the product NFT; when the product performs a secondary transaction, a secondary delivery transmitter host executes a secondary delivery function to set a delivery condition and requests a secondary delivery receiver host to provide an encrypted delivery content; when the product is delivered and the encrypted delivery content satisfies the delivery condition, an ownership of the product NFT is transferred. Therefore, the technical effect of improving consistency between ownerships of a product entity and a product NFT can be achieved.

Abstract: An anonymous disclose and many-to-many recognition system based on blockchain and identity confirmation allowance and a method thereof are disclosed. In the system, an exposing host generates a one-time address and encrypt the disclosure data into the encrypted data, write the encrypted data into the blockchain; an identity confirmation host generates a valid flag, and an announcement host decrypts the encrypted data to generate a corresponding receipt flag, and garbles a correspondence between the decrypted disclosure data and the corresponding one-time address, to generate and write a shuffled recognition announcement to a blockchain, so that when the exposing host detects the presence of the self-owned disclosure data and one-time address in the shuffled recognition announcement, the exposing host writes a recognition flag into the blockchain. Therefore, the technical effect of improving anonymity and allowing identity confirmation can be achieved.

Abstract: An escrowing system for cross-blockchain third-party settlement and a method thereof are disclosed. In the escrowing system, an initiating-end host and an accepting-end host escrow digital assets in smart contracts in different blockchains, respectively, and based on a result of delivery of trading entities outside the blockchain, the digital assets escrowed by the smart contracts are transferred or returned, and the arbitration host is permitted to perform trading arbitration, without managing the trading entities, to determine whether the delivery outside the blockchain succeeds. When the arbitration host determines that the delivery outside the blockchain succeeds, the arbitration host can transfer the digital assets escrowed by the initiating-end host and the accepting-end host without consent of the initiating-end host, so as to achieve a technical effect of improving reliability of escrow.

Abstract: A management system for asset dynamic value based on blockchain and a method thereof are disclosed. In the management system, an asset management host, an asset holding host and a transaction object host serving as nodes on a blockchain network are provided; the asset management host creates a smart contract associated with an asset to record statuses of funds, holdings and sub-assets; the asset holding host and the transaction object host are permitted to execute functions in the smart contract, so as to perform the transfer between the funds and the holdings and store the sub-assets in the smart contract. Therefore, the technical effect of improving convenience and credibility in dynamic management of asset value can be achieved.

Abstract: A proof aggregating system for asset management traceability based on blockchain and a method thereof are disclosed. In the system, a creator host deploys a smart contract associated with an asset on a blockchain network through, so as to aggregate a proof value of digital file associated with the asset for further verification and management; a holder host executes an authorization function to set a writer host to be permitted to access the smart contract, the writer host calculates a proof value based on the digital file associated with the asset, and executes a write function to write the proof value into a proof record of the smart contract, so as to provide a verification host to verify the aggregated proof record. As a result, the technical effect of improving authenticity and credibility of the asset management traceability can be achieved.
