    • An adhesive composition of the present invention includes, as a main component, a polymer produced by copolymerization of a monomer composition including: styrene; a (meth)acrylic acid alkyl ester having a chain structure; a (meth)acrylic acid ester having an aliphatic ring; and a (meth)acrylic acid ester having an aromatic ring, wherein: the styrene is contained in a range of 40 to 69 parts by mass; the (meth)acrylic acid alkyl ester having the chain structure is contained in a range of 20 to 30 parts by mass; the (meth)acrylic acid ester having the aliphatic ring is contained in a range of 10 to 25 parts by mass; and the (meth)acrylic acid ester having the aromatic ring is contained in a range of 1 to 5 parts by mass, where the total amount of the above components is 100 parts by mass. This allows for provision of an adhesive composition having high adhesive strength under high-temperature environment, as well as high heat resistance, high alkali resistance, and easiness in stripping from semiconductor wafers and the like even after high-temperature processing.

    • A processed substrate of the present invention includes a translucent substrate having a plurality of through-holes, in each of which there is a gap from 0 to 5 μm between (a) a straight line which passes through a central point of an opening plane of the each of the plurality of through-holes and which is perpendicular to the opening plane and (b) a straight line which passes through a central point of the other opening plane of the each of the plurality of through-holes and which is perpendicular to the other opening plane, thereby making it possible to provide (i) a processed substrate having through-holes in each of which central axes are aligned, which can be easily produced with high productivity, and (ii) a production method thereof. Further, a production method of the present invention of a processed glass substrate includes: (a) forming photosensitive resin layers on surfaces of a glass substrate; (b) forming a through-hole in the glass substrate; and (c) immersing the glass substrate in acid, with the photosensitive resin layers remaining on the both surfaces. Accordingly, it is unnecessary to perform smoothing the surfaces of the glass substrate after the step (c), thereby successfully producing a processed glass substrate having a through-hole with high productivity.
    • 本发明的处理衬底包括具有多个通孔的透光性衬底,每个通孔在(a)穿过开口平面的中心点的直线之间存在0至5μm的间隙 所述多个通孔中的每一个并且垂直于所述开口平面,并且(b)直线,其穿过所述多个通孔中的每一个的另一开口平面的中心点并且垂直于 从而能够提供(i)具有通孔的处理基板,其中每个中心轴对准,其可以容易地以高生产率生产,和(ii)其制造方法。 此外,本发明的加工玻璃基板的制造方法包括:(a)在玻璃基板的表面上形成感光性树脂层; (b)在玻璃基板中形成通孔; 和(c)将玻璃基板浸入酸中,其中感光性树脂层保留在两面上。 因此,不需要在步骤(c)之后对玻璃基板的表面进行平滑化,从而以高生产率成功制造具有通孔的加工玻璃基板。
