  • Patent number: 12002867
    Abstract: The present disclosure describes a semiconductor structure and a method for forming the same. The semiconductor structure can include a substrate, a gate structure over the substrate, a layer of dielectric material over the gate structure, a source/drain (S/D) contact layer formed through and adjacent to the gate structure, and a trench conductor layer over and in contact with the S/D contact layer. The S/D contact layer can include a layer of platinum-group metallic material and a silicide layer formed between the substrate and the layer of platinum-group metallic material. A top width of a top portion of the layer of platinum-group metallic material can be greater than or substantially equal to a bottom width of a bottom portion of the layer of platinum-group metallic material.

  • Patent number: 12002774
    Abstract: An integrated circuit (IC) comprising an enhanced passivation scheme for pad openings and trenches is provided. In some embodiments, an interlayer dielectric (ILD) layer covers a substrate and at least partially defines a trench. The trench extends through the ILD layer from a top of the ILD layer to the substrate. A conductive pad overlies the ILD layer. A first passivation layer overlies the ILD layer and the conductive pad, and further defines a pad opening overlying the conductive pad. A second passivation layer overlies the ILD layer, the conductive pad, and the first passivation layer, and further lines sidewalls of the first passivation layer in the pad opening and sidewalls of the ILD layer in the trench. Further, the second passivation layer has a low permeability for moisture or vapor relative to the ILD layer.

  • Publication number: 20240128291
    Abstract: A sensor package structure includes a substrate, a sensor chip disposed on and electrically coupled to the substrate, a light-permeable layer, an adhesive layer having a ring-shape and sandwiched between the sensor chip and the light-permeable layer, and an encapsulant formed on the substrate. The adhesive layer has two adhering surfaces having a same area and a middle cross section located at a middle position between the two adhering surfaces. An area of the middle cross section is 115% to 200% of an area of any one of the two adhering surfaces. The adhesive layer can provide for light to travel therethrough, and enables the light therein to change direction and to attenuate. The sensor chip, the adhesive layer, and the light-permeable layer are embedded in the encapsulant, and an outer surface of the light-permeable layer is at least partially exposed from the encapsulant.

  • Publication number: 20170202433
    Abstract: A wireless visible bougie based on cloud transmission mainly includes a WIFI or 3G/4G communication module and mediation platform server placed on an internet cloud. The WIFI or 3G/4G communication module is connected to and exchanges data with an endpoint of a mediation platform server placed on a cloud of an internet through the internet to store image data captured by the visible bougie, thereby building a database in the mediation platform server of the cloud and then forming data control on the cloud, and allowing relevant personnel to download the data from the cloud for observation so as to achieve the objects of mutual observation and learning.
