Abstract: In a method of manufacturing a semiconductor device, an n-type source/drain epitaxial layer and a p-type source/drain epitaxial layer respectively formed, a dielectric layer is formed over the n-type source/drain epitaxial layer and the p-type source/drain epitaxial layer, a first opening is formed in the dielectric layer to expose a part of the n-type source/drain epitaxial layer and a second opening is formed in the dielectric layer to expose a part of the p-type source/drain epitaxial layer, and the n-type source/drain epitaxial layer and the p-type source/drain epitaxial layer respectively recessed. A recessing amount of the n-type source/drain epitaxial layer is different from a recessing amount of the p-type source/drain epitaxial layer.

Abstract: A method includes forming a dummy gate over a semiconductor fin; forming a source/drain epitaxial structure over the semiconductor fin and adjacent to the dummy gate; depositing an interlayer dielectric (ILD) layer to cover the source/drain epitaxial structure; replacing the dummy gate with a gate structure; forming a dielectric structure to cut the gate structure, wherein a portion of the dielectric structure is embedded in the ILD layer; recessing the portion of the dielectric structure embedded in the ILD layer; after recessing the portion of the dielectric structure, removing a portion of the ILD layer over the source/drain epitaxial structure; and forming a source/drain contact in the ILD layer and in contact with the portion of the dielectric structure.

Abstract: A computer system includes an openflow switch, configured to receive a plurality of packets; a network controller, coupled to the openflow switch and configured to determine a route of each of the plurality of packets; and a detecting and defending system, configured to perform transformation of information formats of the plurality of packets, retrieve and label the plurality of packets to determine whether the plurality of packets are abnormal or not and generate a defending determination.
