能够分散应力的半导体装置
摘要：
提供一种半导体装置。所述半导体装置包括：半导体基底，包括设置在其中的电路层；焊盘，设置在半导体基底上，焊盘电连接到电路层；以及金属层，电连接到焊盘。金属层包括：第一通路，电连接到焊盘，第一通路在金属层与电路层之间提供电路径；以及第二通路，朝向半导体基底突出，第二通路在半导体基底上支撑金属层。
摘要（英）：

A method tests a redundancy area of a semiconductor memory device. The method includes receiving a redundancy address to select a redundancy area including spare memory cells to repair normal memory cells, checking the redundancy address based on repair use information to determine whether the redundancy area is an actually repaired area, enabling the redundancy area when the redundancy area is the actually repaired area, and outputting data read from the enabled redundancy area to practically perform a redundancy area test.
