The semiconductor device includes a semiconductor substrate and a multi-layer wiring portion including insulating layers and wiring layers alternately stacked one on another on a main surface of the semiconductor substrate. The resistance value of a wiring layer located on an upper side of an adjacent pair of wiring layers is lower than or equal to that of a wiring layer located on a lower side of the adjacent pair, and the resistance value of the lowermost layer is higher than that of the uppermost layer. The specific inductive capacity of an insulating layer located on an upper side of an adjacent pair of insulating layers is higher than or equal to that of an insulating layer located on a lower side of the adjacent pair, and the specific inductive capacity of the lowermost layer is lower than that of the uppermost layer.

摘要:
A semiconductor device has a metal silicide on silicon conductor formed using a salicide process. The metal silicide layer of the conductor includes boron which improves the morphology and conductivity of the metal silicide layer. Implanting boron into the metal silicide layer or the metal to be silicided prevents the metal silicide from aggregating during a subsequent annealing or other heating process. This process allows narrower conductors to be formed without undesirable increases in the resistance of the metal silicide layer. The boron incorporating salicide process is compatible with CMOS processes.

A semiconductor device comprises a MOSFET of LDD structure, in which the gate electrode structure comprises an oxide film interposed between a poly-Si layer and a refractory metal layer or a metal silicide. The oxide film prevents the metal or metal silicide from being diffused into the gate oxide film during the heating step included in the process of manufacturing the semiconductor device. Also, a side wall spacer is formed of poly-Si to achieve an electrical connection between the poly-Si layer and the layer of the metal having a high melting point or of the metal silicide so as to constitute a part of the gate electrode.

A method for manufacturing a light emitting device includes forming a multilayer body including a light emitting layer so that a first surface thereof is adjacent to a first surface side of a translucent substrate. A dielectric film on a second surface side opposite to the first surface of the multilayer body is formed having first and second openings on a p-side electrode and an n-side electrode. A seed metal on the dielectric film and an exposed surface of the first and second openings form a p-side metal interconnect layer and an n-side metal interconnect layer separating the seed metal into a p-side seed metal and an n-side seed metal by removing a part of the seed metal. A resin is formed in a space from which the seed metal is removed.
