摘要:
An interlayer insulating film is disposed above an image pickup region and a peripheral region of the semiconductor substrate. An opening is formed in the interlayer insulating film at a position overlying a photoelectric conversion portion. A waveguide member is formed above the image pickup region and the peripheral region of the semiconductor substrate. A part of the waveguide member, which part is disposed above the peripheral region, is removed such that the interlayer insulating film is exposed.

Present invention provides an air filter material using a laminated electret nonwoven fabric subjected to electret processing in which one layer or a plurality of layers of nonwoven fabrics (referred to as nonwoven fabric B) including fibers having a mean fiber diameter in the range of 10 micrometers to 100 micrometers and being larger than a mean fiber diameter of fibers constituting nonwoven fabric A are laminated on at least one side of a nonwoven fabric (referred to as nonwoven fabric A) obtained by mixing two kinds of fibers having a mean fiber diameter in the range of 0.1 micrometer to 15 micrometers and having a different melting point (fibers having a lower melting point are defined as fibers D and fibers having a higher melting point are defined as fibers E), and a laminated electret filter material having a low pressure loss and a high collection efficiency. The filter material is suitably used for a medical mask, an industrial mask, a general purpose mask or the like.

摘要:
A stretchable laminated sheet with hydrophilic properties, which particularly has an excellent feeling and stability in wearing and is capable of efficiently enhancing the effect and efficacy brought about by a liquid component on a skin or other object, when the stretchable laminated sheet is impregnated with the liquid component and wet and then used on the skin or other object. A stretchable laminated sheet, which is obtained by partially thermocompression-bonding and laminating a hydrophilic short fiber layer extensible in at least one direction and an microfiber layer having a elastomer long fiber of a fiber diameter of 15 μm or less at 50% or more by weight, wherein discontinuous and regular concave and convex parts caused by the partial thermocompression bonding are formed on a surface of the hydrophilic short fiber layer that is exposed on one surface of the stretchable laminated sheet, the total area of the concave parts is in a range of 3 to 40% of the area of the surface of the hydrophilic short fiber layer, and at least the elastomer long fiber of the microfiber layer is softened and consequently joined to a fiber constituting the hydrophilic short fiber layer in a sheet thickness direction of a section where the concave parts exist, whereby the hydrophilic short fiber layer and the microfiber layer are integrated with each other.
