Abstract: A three-dimensional semiconductor device includes gate electrodes including pad regions sequentially lowered by a first step portion in a first direction and sequentially lowered by a second step portion in a second direction perpendicular to the first direction, the second step portion being lower than the first step portion, wherein a length of a single pad region among pad regions sequentially lowered by the second step portion in the second direction is less than a length of a remainder of the pad regions in the second direction.

Abstract: Disclosed herein are glass bubbles that are surface treated to obtain a metallic texture, and have a similar specific gravity to that of plastic. Thus, there is a low possibility of occurrence of appearance defects even when a material obtained by compounding the glass bubbles and the plastic is injection molded and a master batch including the glass bubbles and plastic to improve a miscibility of the glass bubbles and the plastic. The glass bubbles each include a spherical shell and a surface treatment layer formed on a surface of the shell, the spherical shell having a hollow hole so as to decrease a specific gravity of the glass bubbles and the surface treatment layer being formed by surface treatment to obtain a metallic texture.

Abstract translation: 本文公开了经表面处理以获得金属质感并具有与塑料相似的比重的玻璃泡。 因此，即使通过混合玻璃泡和塑料得到的材料被注射成型，并且包含玻璃泡和塑料的母料也可能发生外观缺陷，以提高玻璃泡和塑料的混溶性。 玻璃泡各自包括球壳和形成在壳体的表面上的表面处理层，球形壳体具有中空孔，以便降低玻璃泡的比重，并且通过表面处理形成表面处理层 获得金属质感。
