  • Publication number: 20240145370
    Abstract: A semiconductor device includes a first region and a second region, and the second region surrounds the first region. The semiconductor device includes at least one electronic unit, a redistribution structure, a plurality of first pads, and a plurality of second pads. The redistribution structure may be electrically connected to at least one electronic unit. A plurality of first pads are arranged on the redistribution structure and correspondingly to the first region. There is a first pitch between two adjacent first pads. A plurality of second pads are arranged on the redistribution structure and correspondingly to the second region. There is a second pitch between two adjacent second pads, so that the first pitch is smaller than the second pitch.

  • Publication number: 20240102194
    Abstract: A plating system and a method thereof are disclosed. The plating system performs a N-stage plating drilling filling process in which a M-th stage plating drilling filling process with a M-th current density is performed on a hole of a substrate for a M-th plating time to form a M-th plating layer on the to-be-plated layer, wherein N is a positive integer equal to or greater than 3, and M is a positive integer positive integer in a range of 1 to N. Therefore, the technical effect of providing a higher drilling filling rate than conventional plating filling technology under a condition that a total thickness of plating layers is fixed can be achieved.

  • Publication number: 20240074037
    Abstract: A method of manufacturing an electronic device, including the following steps, is provided. A first dielectric layer and a second dielectric layer are provided. The first dielectric layer has a first surface and a second surface opposite to each other, and the second dielectric layer has a third surface and a fourth surface opposite to each other. A first unit is formed on the first surface or the second surface of the first dielectric layer. The first dielectric layer and the second dielectric layer are combined to form a substrate structure. The second surface of the first dielectric layer faces the third surface of the second dielectric layer. A dielectric loss of the first unit is less than a dielectric loss of the first dielectric layer. The method of manufacturing the electronic device of the embodiment of the disclosure can reduce the dielectric loss by using the unit.

  • Patent number: 6274413
    Abstract: A method for fabricating a polysilicon thin film transistor combining the channel oxidation process and the plasma hydrogenation process is disclosed. The fabrication process includes the following steps: (a) forming a field oxide layer on a silicon substrate, (b) forming a polysilicon layer on a portion of the field oxide layer to serve as a gate, (c) forming a gate oxide on the polysilicon layer and another portion of the field oxide layer, (d) forming a polysilicon channel on the gate oxide layer, (e) defining a source region and a drain region in a portion of the polysilicon channel, (f) oxidizing another portion of the polysilicon channel, (g) forming a dielectric layer on said polysilicon channel, and (h) hydrogenating said polysilicon thin film transistor by plasma. Such a combination results in an better efficiency for passivating the tail state traps, and can prevent the polysilicon thin film from being damaged caused by the plasma glow during the plasma hydrogenation process.
