Abstract: A semiconductor device structure is provided. The semiconductor device structure includes a substrate, a conductive feature on the substrate, and an electrical connection structure on the conductive feature. The electrical connection includes a first grain made of a first metal material, and a first inhibition layer made of a second metal layer that is different than the first metal material. The first inhibition layer extends vertically along a first side of a grain boundary of the first grain and laterally along a bottom of the grain boundary of the first grain.

Abstract: A contact stack of a semiconductor device includes a source/drain feature, a silicide layer wrapping around the source/drain feature, a seed metal layer in direct contact with the silicide layer, and a conductor in contact with the seed metal layer. The contact stack excludes a metal nitride layer in direct contact with the silicide layer.

Abstract: The present invention discloses a message transmission method. A first portable device transmits an identity information of a first wireless signal transmitter and a message content to a cloud server. The cloud server analyzes the message content to obtain a message tag of the message content, and obtain a wireless signal transmitter tag of the first wireless signal transmitter according to the identity information. The cloud server then obtains at least one target identity information representing at least one target wireless signal transmitter by using the message tag and the wireless signal transmitter tag, to obtain an association between the message content and the at least one target identity information. When receiving a second identity information, a second portable device compares the second identity information with the at least one target identity information and receives the message content from the cloud server.
