  • Patent number: 7217968
    Abstract: A novel image sensor cell structure and method of manufacture. The imaging sensor comprises a substrate, a gate comprising a dielectric layer and gate conductor formed on the dielectric layer, a collection well layer of a first conductivity type formed below a surface of the substrate adjacent a first side of the gate conductor, a pinning layer of a second conductivity type formed atop the collection well at the substrate surface, and a diffusion region of a first conductivity type formed adjacent a second side of the gate conductor, the gate conductor forming a channel region between the collection well layer and the diffusion region. Part of the gate conductor bottom is recessed below the surface of the substrate. Preferably, a portion of the gate conductor is recessed at or below a bottom surface of the pinning layer to a depth such that the collection well intersects the channel region.

  • Patent number: 7176506
    Abstract: A radio frequency chip package is formed by assembling a connecting element such as a circuit board or flexible circuit tape having chips thereon with a bottom plane element such as a lead frame incorporating a large thermally-conductive plate and leads projecting upwardly from the plane of the plate. The assembly step places the rear surfaces of the chips on the bottom side of the connecting element into proximity with the thermal conductor and joins the conductive traces on the connecting element with the leads. The resulting assembly is encapsulated, leaving terminals at the bottom ends of the leads exposed. The encapsulated assembly may be surface-mounted to a circuit board. The leads provide robust electrical connections between the connecting element and the circuit board.

  • Patent number: 7154549
    Abstract: Provided is a CCD image sensor wherein driving power and power consumption are reduced without increasing unusable regions. Photodiodes are arranged in a honeycomb form. Each vertical charge-transfer channel is made in such a manner that invasion portions, which invade spaces between the respective photoelectric transducers in photoelectric transducer columns positioned at both sides thereof, and non-invasion portions are alternately and continuously arranged, and the channel extends in the vertical direction to meander between the photodiodes arranged in the honeycomb form. Transfer electrodes extending in the horizontal direction to pass between the photodiodes are formed on the semiconductor substrate as monolayer electrodes. By making the transfer electrodes as the monolayer electrodes in this way, multi-layered poly-silicon electrode structure becomes unnecessary.

  • Patent number: 7068432
    Abstract: A semi-conductor based imager includes a microlens array having microlenses with modified focal characteristics. The microlenses are made of a microlens material, the melting properties of which are selectively modified to obtain different shapes after a reflow process. Selected microlenses, or portions of each microlens, are modified, by exposure to ultraviolet light, for example, to control the microlens shape produced by reflow melting. Controlling the microlens shape allows for modification of the focal characteristics of selected microlenses in the microlens array.

  • Patent number: RE41340
    Abstract: A lock in pinned photodiode photodetector includes a plurality of output ports which are sequentially enabled. Each time when the output port is enabled is considered to be a different bin of time. A specified pattern is sent, and the output bins are investigated to look for that pattern. The time when the pattern is received indicates the time of flight. A CMOS active pixel image sensor includes a plurality of pinned photodiode photodetectors that share buffer transistors. In one configuration, the charge from two or more pinned photodiodes may be binned together and applied to the gate of a shared buffer transistor.
