Abstract: This application provides an electrode sheet and an electrochemical device. The electrode sheet includes a current collector and a functional coating located on at least one surface of the current collector. The functional coating includes a first coating, a second coating and an active material layer that are sequentially stacked on a surface of the current collector. The first coating includes a conductive agent, a binder and a first functional filler, and the second coating includes a conductive agent, a binder and a second functional filler. A mass ratio of the binder in the first coating to the first coating is a1, a mass ratio of the binder in the second coating to the second coating is a2, and a mass ratio of the binder in the active material layer to the active material layer is a3, and a1>a2>a3.

Abstract: A backside illuminated CMOS image sensor and a method of fabricating the sensor are disclosed. The backside illuminated CMOS image sensor includes a first substrate and a second substrate. A plurality of pixel cells are formed in the front side of the first substrate, and a plurality of grooves are formed in the back side. Each of the grooves has at least one sidewall inclined with respect to the back surface of the first substrate. The second substrate is bonded to the first substrate on a side closer to the front side. A method for fabricating such a backside illuminated CMOS image sensor is also disclosed. The grooves formed in the back side of the first substrate can reduce reflection loss of light incident on the back surface and hence enhance quantum efficiency of the backside illuminated CMOS image sensor.

Abstract: A searching method and a searching apparatus are provided.
