摘要： A preferred aim of the invention is to provide technique for improving reliability of semiconductor devices when using a low-dielectric-constant film having a lower dielectric constant than a silicon oxide film to a part of an interlayer insulating film. More specifically, to achieve the preferred aim, an interlayer insulating film IL1 forming a first fine layer is formed of a middle-Young's-modulus film, and thus it is possible to separate an integrated high-Young's-modulus layer (a semiconductor substrate 1S and a contact interlayer insulating film CIL) and an interlayer insulating film (a low-Young's-modulus film; a low-dielectric-constant film) IL2 forming a second fine layer not to let them directly contact with each other, and stress can be diverged. As a result, film exfoliation of the interlayer insulating film IL2 formed of a low-Young's-modulus film can be prevented and thus reliability of semiconductor devices can be improved.

摘要： A stay for keeping an oil control valve fastened to a sleeve extends across the outer surface of a head cover from the oil control valve and is fixed by a screw. Thus, the OCV is removable from the sleeve without dismounting the head cover from the cylinder head by loosening the screw from the outside of the head cover and detaching the stay.

摘要： A valve case includes an attaching portion and a sleeve. The valve case is attached to a cylinder head cover main body formed of resin. The attaching portion is formed of resin and is a portion of the valve case to which an oil control valve is to be attached. The sleeve is embedded in the attaching portion, and has an interior space that permits the oil control valve to be accommodated therein and oil holes. Each oil hole is selectively connected to one of ports of the oil control valve accommodated in the interior space of the sleeve. The sleeve is formed of material having higher rigidity than the resin forming the attaching portion. Therefore, the valve case prevents deformation of the attaching portion.
