    摘要: A semiconductor wafer and its manufacturing method are provided where the current driving capability of a MOS transistor can be sufficiently enhanced. An SOI layer wafer in which an SOI layer (32) is formed has a crystal direction notch (32a) and a crystal direction notch (32b). The SOI layer wafer and a supporting substrate wafer (1) are bonded to each other in such a way that the notch (32a) and a crystal direction notch (1a) of the supporting substrate wafer (1) coincide with each other. When bonding the two wafers by using the notch (32a) and the notch (1a) to position the two wafers, the other notch (32b) of the SOI layer wafer can be engaged with a guide member of the semiconductor wafer manufacturing apparatus to prevent positioning error due to relative turn between the wafers. Thus an MOS transistor with a sufficiently improved current driving capability can be fabricated on the semiconductor wafer with the two wafers positioned in crystal directions shifted from each other.

    摘要: 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.

    摘要: The invention relates to improvements in a method of manufacturing a semiconductor device in which deterioration in a transistor characteristic is avoided by preventing a channel stop implantation layer from being formed in an active region. After patterning a nitride film (22), the thickness of an SOI layer 3 is measured (S2) and, by using the result of measurement, etching conditions (etching time and the like) for SOI layer 3 are determined (S3). To measure the thickness of SOI layer 3, it is sufficient to use spectroscopic ellipsometry which irradiates the surface of a substance with linearly polarized light and observes elliptically polarized light reflected by the surface of a substance. The etching condition determined is used and a trench TR2 is formed by using patterned nitride film 22 as an etching mask (S4).

    摘要: It is an object to provide a semiconductor device having an SOI structure in which an electric potential of a body region in an element formation region isolated by a partial isolation region can be fixed with a high stability. A MOS transistor comprising a source region (51), a drain region (61) and an H gate electrode (71) is formed in an element formation region isolated by a partial oxide film (31). The H gate electrode (71) electrically isolates a body region (13) formed in a gate width W direction adjacently to the source region (51) and the drain region (61) from the drain region (61) and the source region (51) through “I” in a transverse direction (a vertical direction in the drawing), a central “−” functions as a gate electrode of an original MOS transistor.
