  • Publication number: 20240071999
    Abstract: A first polymer layer is formed across a package region and a test region. A first metal pattern is formed in the package region and a first test pattern is simultaneously formed in the test region. The first metal pattern has an upper portion located on the first polymer layer and a lower portion penetrating through the first polymer layer, and the first test pattern is located on the first polymer layer and has a first opening exposing the first polymer layer. A second polymer layer is formed on the first metal pattern in the package region and a second test pattern is simultaneously formed on the first test pattern in the test region. The second polymer layer has a second opening exposing the upper portion of the first metal pattern, and the second test pattern has a third opening greater than the first opening of the first test pattern.

  • Publication number: 20240071939
    Abstract: A semiconductor structure includes a composite redistribution structure, a first interconnect device and an integrated circuit (IC) package component. The composite redistribution structure includes a first redistribution structure, a second redistribution structure and a third redistribution structure. The second redistribution structure is located between the first redistribution structure and the third redistribution structure. The first interconnect device is embedded in the second redistribution structure. The first interconnect device includes a plurality of metal connectors leveled with a surface of the second redistribution structure and electrically connected to the third redistribution structure. The IC package component is disposed over the third redistribution structure and electrically connected to the first interconnect device via the third redistribution structure.

  • Publication number: 20240012493
    Abstract: A stylus used to interact with a plurality of positioning transmission electrodes includes a receiver and a demodulation circuit. The receiver receives an uplink signal carrying a plurality of positioning signals which are transmitted from the plurality of positioning transmission electrodes. The demodulation circuit, coupled to the receiver, demodulates the uplink signal to generate at least one positioning signal among the plurality of positioning signals.

  • Publication number: 20230236677
    Abstract: A stylus control circuit used to control a stylus includes a positioning signal generator. The positioning signal generator is used to generate a first positioning signal having a first frequency and transmit the first positioning signal to the stylus through a first positioning transmission electrode. Wherein, the first frequency corresponds to a position of the first positioning transmission electrode, and the first positioning signal is a frequency signal without carrying any digital data.

  • Publication number: 20060150245
    Abstract: A system and method of automatically transforming instant message transmission modes on the Internet is disclosed. The transformation system is applied to a Java-based instant messenger and could be automatically transformed to four transmission modes in accordance with different network environments. The four transmission modes include the socket mode (i.e. direct connection through socket), HTTP 1.1 mode (i.e. connection through a proxy server and a firewall that both support HTTP 1.1), HTTP 1.0 mode (i.e. connection through a proxy server and a firewall that both support HTTP 1.0) and a pure-HTML mode (i.e. without JAVA applet).
