  • Publication number: 20230335569
    Abstract: A method is provided for light shielding a charge storage device of an image sensor pixel that includes a photosensitive device and the charge storage device and a dielectric layer covering the photosensitive device and the charge storage device. The method includes performing etching of the dielectric layer to define an undercut volume beneath the dielectric layer and an access opening through the dielectric layer to the undercut volume, and performing physical vapor deposition (PVD) of a light blocking material to both: fill the undercut volume with the light blocking material to form a light blocking layer covering the charge storage device, and fill the access opening with the light blocking material to form a light blocking plug. An image sensor pixel formed by such a process, and an image sensor comprising an array of image sensor pixels, are also disclosed.

  • Patent number: 9073208
    Abstract: A gripper apparatus and its control method are provided. The gripper apparatus includes at least one gripper unit, and each gripper unit is configured with a first connecting rod and a second connecting rod. In addition, there is an elastic part disposed at the joint of the first and the second connecting rods, an encoder and a controller. Thereby, the controller is enabled to control the gripper apparatus to move toward an object in a first mode so as to enable the gripper unit to engage the object and thus exert a force upon the object. Consequently, the elastic part is deformed and the deformation of the elastic part is measured and encoded by the encoder into a force information to be transmitted to the controller for enabling the controller to switch the control of the gripper apparatus into a second mode according to the force information.
