A component-incorporated wiring substrate is provided. Some embodiments include a plate-like component incorporated in a core substrate and a build-up layer having an insulation layer and a conductor layer disposed in alternating layers. The component has terminal electrodes formed at its opposite ends having a side surface and a main surface. An insulation layer disposed on the main surface of the component has via conductors formed therein which are connected to the side surfaces and the main surfaces of the respective terminal electrodes. The via conductors are tapered, such that their via diameter decreases in a direction toward the terminal electrode, and their via diameter at a position where they connect to the main surface is greater than a length of the main surface. Accordingly, the area of connection between the via conductors and the corresponding terminal electrodes is increased, improving connection reliability through enhancement of tolerance for positional deviation.

The present invention provides a method of fabricating a semiconductor device in which deterioration in a transistor characteristic is prevented by preventing a channel stop implantation layer from being formed in an active region. A resist mask is formed so as to have an opening over a region in which a PMOS transistor is formed. Channel stop implantation is performed with energy by which ions pass through a partial isolation oxide film and a peak of an impurity profile is generated in an SOI layer, thereby forming a channel stop layer in the SOI layer under the partial isolation oxide film, that is, an isolation region. An impurity to be implanted here is an N-type impurity. In the case of using phosphorus, its implantation energy is set to, for example, 60 to 120 keV, and the density of the channel stop layer is set to 1×10¹⁷ to 1×10¹⁹/cm³. At this time, the impurity of channel stop implantation is not stopped in the SOI layer corresponding to the active region.

A MOSFET device in strained silicon-on-SiGe and a method of forming the device are described. The said device achieves reduced junction leakage due to the lower band-gap values of SiGe. The method consists of forming isolation trenches in a composite strained-Si/SiGe substrate and growing a liner oxide by wet oxidation such that oxidation is selective to SiGe only, with negligible oxidation of silicon surfaces. Selective oxidation results in oxide encroachment under strained-Si, thereby reducing the junction area after device fabrication is completed. Reduced junction area leads to reduced n⁺/p or p⁺/n junction leakage current.
