  • Patent number: 12237354
    Abstract: Chip packages and methods for forming the same are provided. The method includes providing a substrate having upper and lower surfaces, and having a chip region and a scribe-line region surrounding the chip region. The substrate has a dielectric layer on its upper surface. A masking layer is formed over the substrate to cover the dielectric layer. The masking layer has a first opening exposing the dielectric layer and extending in the extending direction of the scribe-line region to surround the chip region. An etching process is performed on the dielectric layer directly below the first opening, to form a second opening that is in the dielectric layer directly below the first opening. The masking layer is removed to expose the dielectric layer having the second opening. A dicing process is performed on the substrate through the second opening.

  • Publication number: 20250058286
    Abstract: A moisture-permeable composite membrane is manufactured by the step of subjecting a mixture to a crosslinking treatment. The mixture contains a polyisoprene, a polyurethane with a polar functional group, a crosslinking agent, and a vulcanizing agent. In the mixture, a weight ratio of the polyurethane with the polar functional group to the polyisoprene ranges from 1:0.55 to 1:6.60. A method for manufacturing the moisture-permeable composite membrane is also provided.

  • Publication number: 20240048149
    Abstract: A complementary current-steering digital-to-analog converter (DAC) including a p-type DAC as well as an n-type DAC is shown. The p-type DAC has p-type current sources, and the n-type DAC has n-type current sources. The p-type and n-type current sources are coupled to a first input terminal or a second input terminal of a transimpedance amplifier (TIA) according to the digital input of the complementary current-steering DAC. In response to the digital input changing from a first value to a second value that is greater than the first value, one or more n-type current sources connected to the second input terminal of the TIA are switched so that they are connected to the first input terminal of the TIA.

  • Publication number: 20240039478
    Abstract: A circuit with a pseudo class-AB structure is shown. The circuit has an output stage, a first capacitor, and a first impedance component. The output stage has a first PMOS (p-type Metal-Oxide-Semiconductor Field-Effect Transistor) and a first NMOS (n-type MOSFET). The first connection node between the drain terminal of the first PMOS and the drain terminal of the first NMOS is coupled to the first output terminal of the circuit. The first capacitor is coupled between the gate terminal of the first PMOS and the gate terminal of the first NMOS. The first impedance component is coupled in parallel with the first capacitor between the gate terminal of the first PMOS and the gate terminal of the first NMOS.

  • Patent number: 11114981
    Abstract: Disclosed is a differential amplifier including an input circuit, a detecting and controlling circuit, and an output circuit. The input circuit outputs input current to two output nodes according to the voltage of a differential input signal and the voltage of a bias node. The detecting and controlling circuit outputs compensative current to the two output nodes according to control bias voltage and the voltage of the bias node, in which the voltage of the bias node and the compensative current relate to the voltage of the differential input signal. The output circuit is coupled to the two output nodes and outputs a differential output signal according to the sum of the input current and the compensative current. Due to the detecting and controlling circuit outputting the compensative current, the differential amplifier prevents itself from entering a deadlock state even though the input current is insufficient or zero.
