    • A method of manufacturing a back side illumination image sensor is provided. The method can include forming an ion implantation layer in a front side of a first substrate, forming a photodetector and a readout circuit on the first substrate, forming an interlayer dielectric layer and a metal line on the front side of the first substrate, bonding a second substrate with the front side of the first substrate, removing a lower portion of the first substrate on the basis of the ion implantation layer, performing an annealing process with respect on a back side of the first substrate, and forming a microlens over the photodetector.
    • 提供了制造背面照明图像传感器的方法。 该方法可以包括在第一基板的前侧形成离子注入层,在第一基板上形成光电检测器和读出电路,在第一基板的正面上形成层间电介质层和金属线, 第二基板,其具有第一基板的前侧,基于离子注入层去除第一基板的下部,相对于第一基板的背面执行退火处理,并且在光电检测器上形成微透镜 。
