    Abstract: PURPOSE: A mask material composition is provided to enable use for a diffusion barrier of an impurity diffusing component into a semiconductor substrate. CONSTITUTION: A mask material composition comprises a siloxane resin containing a repeating unit represented by chemical formula (a1). In chemical formula (a1), R1 is a single bond or C1~5 alkylene group; and R2 is C6~20 aryl group. A method for forming an impurity diffusion layer comprises the steps of: selectively applying the mask material composition to a semiconductor substrate; and selectively applying impurity diffusion components to the semiconductor substrate using the mask material composition as a mask.

    Abstract translation: 目的:提供掩模材料组合物,以使得能够将杂质扩散组分的扩散势垒用于半导体衬底。 构成:掩模材料组合物包含含有由化学式(a1)表示的重复单元的硅氧烷树脂。 在化学式(a1)中,R1是单键或C1〜5亚烷基; R2为C6〜20芳基。 一种用于形成杂质扩散层的方法包括以下步骤:将掩模材料组合物选择性地施加到半导体衬底; 并使用掩模材料组合物作为掩模,将杂质扩散组分选择性地施加到半导体衬底。
