  • Publication number: 20240145379
    Abstract: Methods and semiconductor devices are provided. A method includes determining a location of a polyimide opening (PIO) corresponding to an under-bump metallization (UBM) feature in a die. The die includes a substrate and an interconnect structure over the substrate. The method also includes determining a location of a stacked via structure in the interconnect structure based on the location of the PIO. The method further includes forming, in the interconnect structure, the stacked via structure comprising at most three stacked contact vias at the location of the PIO.

  • Publication number: 20240105744
    Abstract: An image sensor includes a photoelectric conversion layer, a plurality of deep trench isolations, a first color filter, a first deflector, and a covering layer. The photoelectric conversion layer includes a first photodiode and a second photodiode. The deep trench isolations separate the first photodiode and the second photodiode, in which a pixel dimension is determined by a distance between two adjacent deep trench isolations. The first color filter is disposed on the first photodiode and the second photodiode. The first deflector is disposed on the first color filter. The covering layer covers and surrounds the first deflector. A refractive index of the covering layer is greater than a refractive index of the first deflector, and a difference value between the refractive index of the covering layer and the refractive index of the first deflector is in a range from 0.15 to 0.6.

  • Publication number: 20130085712
    Abstract: An inertial sensing input apparatus includes a motion sensing module, a state determination module, an attitude estimation module, a coordinate transformation module, a gravity elimination module, an integral operation module, a data storage module, a trajectory modification module and a trajectory removal module. When the inertial sensing input apparatus is in a moving time period, the coordinate transformation module transforms a relative acceleration measured by the motion sensing module to an absolute acceleration based on a rotational attitude estimated by the attitude estimation module. The integral operation module calculates a velocity and a displacement based on an absolute acceleration revised by the gravity elimination module and forwards them to the data storage module. When the Kth moving time period is detected by the state determination module, the trajectory modification module modifies a moving trajectory.
