半导体芯片
摘要：
本发明提供一种不依赖于焊料的涂敷量的控制而使凸块高度对齐的半导体芯片。半导体芯片具备：半导体基板，具有主面；第一电极，形成在半导体基板的主面上；第二电极，形成在半导体基板的主面上；第一绝缘层，形成在第一电极的一部分上；第一凸块，形成在第一电极的另一部分以及第一绝缘层上，并且与第一电极电连接；以及第二凸块，形成在第二电极上，并且在半导体基板的主面的俯视下具有比第一凸块的面积大的面积，通过第一绝缘层对半导体基板的主面的法线方向上的从半导体基板的主面到第一凸块的上表面的距离进行调整。
摘要（英）：

The present invention provides a semiconductor chip in which the bump height is aligned without depending on the control of the amount of application of solder. The semiconductor chip includes a semiconductor substrate having a main surface, first and second electrodes, a first insulating layer, and first and second bumps. The first and second electrodes are formed above the main surface of the semiconductor substrate. The first insulating layer is formed above a first portion of the first electrode. The first bump is formed above a second portion of the first electrode and above the first insulating layer and is electrically connected to the first electrode. The second bump is formed above the second electrode. The area of the second bump is larger than that of the first bump in a plan view of the main surface of the semiconductor substrate. The first insulating layer adjusts the distance from the main surface of the semiconductor substrate to the top surface of the first bump in a direction normal to the main surface.
