Abstract: A semiconductor device includes a plurality of channel layers vertically separated from one another. The semiconductor device also includes an active gate structure comprising a lower portion and an upper portion. The lower portion wraps around each of the plurality of channel layers. The semiconductor device further includes a gate spacer extending along a sidewall of the upper portion of the active gate structure. The gate spacer has a bottom surface. Moreover, a dummy gate dielectric layer is disposed between the gate spacer and a topmost channel layer of plurality of channel layers. The dummy gate dielectric layer is in contact with a top surface of the topmost channel layer, the bottom surface of the gate spacer, and the sidewall of the gate structure.

Abstract: A component-embedded packaging structure is provided, in which a plurality of metal layers are formed on an inactive surface of a semiconductor chip so as to serve as a buffer portion, and the semiconductor chip is disposed on a carrying portion with the buffer portion via an adhesive. Then, the semiconductor chip is encapsulated by an insulating layer, and a build-up circuit structure is formed on the insulating layer and electrically connected to the semiconductor chip. Therefore, the buffer portion can prevent delamination from occurring between the semiconductor chip and the adhesive on the carrying portion if the semiconductor chip has a CTE (Coefficient of Thermal Expansion) less than a CTE of the adhesive.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A safety electric socket in which two spring-supported doorplates are respectively pivoted to a holder block to block the neutral and hot slots against outside dust and water and to stop the spring-supported on/off switching button from downward movement. The doorplates are opened for allowing downward movement of the switching button to switch on power supply when the neutral and hot blades of an electric plug are respectively inserted into the neutral and hot slots.

Abstract: A composition of human interferon-alpha (IFN-?) subtypes produced from human lymphoblastoid cells is disclosed. These purified IFN-? composition comprise higher specific activities and may be applied in the treatment of cancers, viruses, and immuno diseases.

Abstract: The present disclosure pertains to an integrated post-etch treatment method which is performed after a dielectric etch process. Using the method of the invention, byproducts formed on the sidewalls of contact vias during the dielectric etch process can be removed efficiently. The method of the invention also reduces or eliminates the problem of polymer accumulation on process chamber surfaces. An overlying photoresist layer and anti-reflection layer are removed during the performance of the post-etch treatment method. Typically, after the etch of a dielectric material to define pattern or interconnect filling spaces, a series of post-etch treatment steps is performed to remove residues remaining on the wafer after the dielectric etch process. According to the method of the present invention, a post-etch treatment method including one or more steps is performed after the dielectric etch process, preferably within the same processing chamber in which the dielectric etch process was performed.
