    摘要: The present invention relates to a substrate for an integrated circuit package and, more specifically, to a substrate for an integrated circuit package, which reduces mismatch of coefficients of thermal expansion with a semiconductor chip, thereby preventing or minimizing warpage during a reflow process. To this end, the present invention provides a substrate for an integrated circuit package which is interposed between a semiconductor chip and a printed circuit board to electrically connect the semiconductor chip to the printed circuit board, the substrate comprising: an ultra-thin glass; a first CTE control layer which is formed on the upper surface of the ultra-thin glass and formed of a material having a coefficient of thermal expansion different from the coefficients of thermal expansion of the semiconductor chip and the ultra-thin glass; a first metal thin plate which is formed on the upper surface of the first CTE control layer and connected to the semiconductor chip; and a second metal thin plate which is formed on the lower surface of the ultra-thin glass and connected to the printed circuit board.
