Abstract: A device includes a first semiconductor fin, a second semiconductor fin, a source/drain epitaxial structure, a semiconductive cap, and a contact. The first semiconductor fin and the second semiconductor fin are over a substrate. The source/drain epitaxial structure is connected to the first semiconductor fin and the second semiconductor fin. The source/drain epitaxial structure includes a first protruding portion and a second protruding portion aligned with the first semiconductor fin and the second semiconductor fin, respectively. The semiconductive cap is on and in contact with the first protruding portion and the second protruding portion. A top surface of the semiconductive cap is lower than a top surface of the first protruding portion of the source/drain epitaxial structure. The contact is electrically connected to the source/drain epitaxial structure and covers the semiconductive cap.

Abstract: A method for manufacturing a nanosheet semiconductor device includes forming a poly gate on a nanosheet stack which includes at least one first nanosheet and at least one second nanosheet alternating with the at least one first nanosheet; recessing the nanosheet stack to form a source/drain recess proximate to the poly gate; forming an inner spacer laterally covering the at least one first nanosheet; and selectively etching the at least one second nanosheet.

Abstract: The invention provides a data processing system capable of securing files. The data processing system of the invention divides a data storage device into an unprotected space and a protected space. A protected application resided in an operating system is controlled by an application controlling module residing in the operating system. When the application controlling module receives a file access request information transmitted from the protected application, the application controlling module redirects the file access request information to access a plurality of protected files stored in the protected space in accordance with the file access request information, and then to return the access result of the protected files to the protected application.

Abstract: This invention provides a digital information protecting method executed in an author and a client computer, both having a predetermined information processing software to process a piece of digital information. In the author computer, receive a content key from a server and encrypt the piece of digital information by the content key. Encrypt the content key by a predetermined key encrypting process. Transmit the encrypted information and encrypted content key to the client computer. In the client computer, decrypt the encrypted content key by a corresponding predetermined decrypting process. Decrypt the encrypted information by the content key so that the piece of digital information can be used by the client computer. No matter the client computer is on-line or off-line, it can get the key and decrypt the piece of digital information.
