Appeal No. 2005-1256 Application No. 09/988,593 an isolation film <31> provided in an upper layer part of said SOI layer for isolating said plurality of element forming regions from each other; a first conductivity type semiconductor region <11, 12> provided under said isolation film as part of said SOI layer, said semiconductor region being formed in contact with at least one of said plurality of element forming regions having a first conductivity type among said plurality of element forming regions; and a first conductivity type body region <10> provided in said SOI layer and capable of being externally fixed in electric potential, said body region being in contact with said semiconductor region, wherein said semiconductor region at least partially has a first conductivity type impurity region not mixed with an impurity of a second conductivity type different from said first conductivity type but doped by only an impurity of said first conductivity type. The examiner relies on the following reference: Flaker et al. (Flaker) 6,410,369 Jun. 25, 2002 (filed Jun. 12, 2000) Claims 1-9 stand rejected under 35 U.S.C. §102 (a) as anticipated by Flaker.
