Abstract: A CMOS image sensor unit and a method for fabricating the same are described. The image sensor unit includes a photodiode, a transfer gate, a reset gate, a source follower gate, a floating drain region between the transfer gate and the reset gate, and a PIP capacitor. The lower poly-Si electrode of the PIP capacitor is electrically connected with the floating drain region and the source follower gate to also serve as an interconnect between the floating drain region and the source follower gate. The fabrication method includes forming contact plugs on the floating drain region and the source follower gate, and then forming a PIP capacitor whose lower poly-Si electrode is connected with each contact plug.

Abstract: An image sensor includes a semiconductor substrate having a main surface, a transfer transistor having a transfer gate disposed on the main surface, a light-sensing structure on one side of the transfer gate, a floating diffusion node on the other side of the transfer gate, a reset transistor serially connected to the transfer transistor via the floating diffusion node, a source-follower transistor having a source-follower gate, and a vertical capacitor having a first vertical electrode plate and a second vertical electrode plate. The first vertical electrode plate is electrically connected to the source-follower gate and the floating diffusion node.

Abstract: A protective device for a padlock. The device includes a casing having a connecting member at either top or bottom, a cover formed at the top of the casing and a base formed at the bottom of the casing being connected to the top and bottom of the connecting member by soldering respectively, so that the casing, the cover and the base are adapted to enclose a body of the padlock. The base includes an opening having an annular downwardly extended flange for receiving a keyhole of the padlock, and an extension member having a recessed enlargement at one open end for being hingedly coupled to one side of the base, so that a pivotal movement of the extension member toward the base will snap the enlargement into and seal the opening.
