The disclosed is about a hydroformylation reaction of a cyclic olefin in the presence of a rhodium catalyst, and specifically about recovering the rhodium catalyst. After the cyclic olefin is hydroformylated by the rhodium catalyst, the product solution is added an extraction liquid including a cycloalkyl alcohol and separated into two layers. The upper layer is substantially made up of the rhodium catalyst solution, and the lower layer is substantially made up of the cycloalkyl aldehyde and the extraction solution including cycloalkyl alcohol.

A slotted set screw includes a slot in an upper end surface, and a cut metal waste storing recess respectively formed at two ends of the slot. The cut metal waste storing recess is defined by a vertical wall and a flat bottom wall to have a large opening, separated from the slot for a little distance. The opening of the cut metal waste storing recess communicates with the outside of the threads of the set screw. Thus, cut metal waste may be stored in the cut metal waste storing recesses during cutting threads of the set screw, without falling into and remaining in the slot to result in extra cleaning work for the waste in the slot.

A substrate having at least two metal oxide semiconductor devices of a same conductive type and a gap formed between the two devices is provided. A first stress layer is formed over the substrate to cover the metal-oxide semiconductor devices and the substrate, filling the gap. An etching back process is then performed to remove a portion of the stress material layer inside the gap. A second stress layer and a dielectric layer are sequentially formed on the first stress layer. The first stress layer and the second stress layer provide a same type of stress. A portion of the second stress layer is removed to form a contact opening. A second conductive layer is filled into the contact opening to form a contact.

A method of manufacturing a MOS transistor device is provided. First, a semiconductor substrate having a gate structure is prepared. The gate structure has two sidewalls and a liner on the sidewalls. Subsequently, a stressed cap layer is formed on the semiconductor substrate, and covers the gate structure and the liner. Next, an activating process is performed. Furthermore, the stressed cap layer is etched to be a salicide block. Afterward, a salicide process is performed to form a silicide layer on the regions that are not covered by the stressed cap layer.

Disclosed is a managing architecture and diagnostic method for remote configuration of heterogeneous local networks, which includes at least one sub-network agent, a local area network (LAN) management module and a remote LAN module. Each sub-network agent manages its sub-networks via its own management protocol, and collects the sub-networks' information. The LAN management module receives the requests from heterogeneous local networks via these sub-network agents, and converts the information associated with each request into a common information module (CIM) to seek a solution for each request. The remote LAN module receives the unsolved requests from the LAN management module via a channel, configures the heterogeneous local networks and uses compatible interface at a remote side to accomplish the management and diagnosis for the heterogeneous local networks.

A method and an apparatus for fabricating a high tensile stress film includes providing a substrate, forming a poly stressor on the substrate, and performing an ultra violet rapid thermal process (UVRTP) for curing the poly stressor and adjusting its tensile stress status, thus the poly stressor serves as a high tensile stress film. Due to a combination of energy from photons and heat, the tensile stress status of the high tensile stress film is adjusted in a relatively shorter process period or under a relatively lower temperature.

A method of manufacturing a metal-oxide-semiconductor (MOS) transistor device is disclosed. A semiconductor substrate and a gate structure positioned on the semiconductor substrate are prepared first. A source region and a drain region are included in the semiconductor substrate on two opposite sides of the gate structure. Subsequently, a stressed cap layer is formed on the semiconductor substrate, and covers the gate structure, the source region and the drain region. Next, an inert gas treatment is performed to change a stress value of the stressed cap layer. Because the stress value of the stressed cap layer can be adjusted easily by means of the present invention, one stressed cap layer can be applied to both the N-type MOS transistor and the P-type MOS transistor.
