    Abstract: A method for separating semiconductor dies of a semiconductor die assembly comprises depositing a first coating on a first surface of the assembly. The assembly comprises a die wafer having a plurality of semiconductor dies and first and second surfaces. A first portion of the die wafer and the first coating is removed between adjacent semiconductor dies to form trenches having an intermediate depth in the die wafer between first and second surfaces such that die corners are formed on either side of the trenches. A protective coating is deposited on the first surface of the die assembly to cover the die corners, trenches and at least a portion of the first coating. The first coating is selectively removed such that portions of the protective coating covering die corners and trenches remain on the die wafer. Adjacent semiconductor dies are separated and the protective coating remains covering the die corners.

  • Publication number: 20220318813
    Abstract: A method for processing financial transactions through a financial authority such as a bank sends a target transaction authorization request from a first ATM or other terminal to a server of the bank. The bank server sends a biometric authentication request to a second terminal recorded as being held by the client desiring the transaction, for example the client's smartphone. The second terminal authenticates the client by reference to its own data and sends an authorization instruction to the first terminal upon successful authentication, the target transaction being then permitted by the bank server. The biometric identification in the second terminal is utilized to perform authentication without uploading private data of the client to the server, thereby improving transaction security. A terminal device and a non-volatile storage medium therein are also disclosed.
