  • Patent number: 12148774
    Abstract: A trench-gate source-follower (TGSF) transistor is described, such as for integration with image sensor pixels. The TGSF transistor is at least partially built into a trench etched into a substrate. A contiguous doped region is implanted around the inner walls of the trench to form a buried-trench current channel. A trench-gate is formed to have at least a buried portion that fills the volume of the trench. A gate oxide layer can be disposed between the buried portion of the trench-gate and the buried-trench current channel. Drain and source regions are formed on either end of the trench-gate. Activating the trench-gate causes current to flow between the drain and source regions via the buried-trench current channel around the buried portion of the trench-gate. The geometry of the buried-trench current channel can effectively increase the width of the active region of the source-follower transistor without increasing its physical layout width.

  • Patent number: 12101477
    Abstract: Disclosed herein are a video processing method, apparatus and storage medium using the resolution of a reference picture. Filtering is performed based on resolutions of reference pictures of blocks forming a boundary. The resolutions of the reference pictures may define filtering. Depending on whether the resolutions of the reference pictures are different from each other, one or more filter selection parameters for filtering may be determined or updated. Further, based on whether the resolutions of the reference pictures are different from each other, the boundary strength of the filter may be determined. Because filtering is defined using the resolutions of reference pictures, performance of encoding and/or decoding may be improved.

  • Patent number: 12097385
    Abstract: A lung phantom unit for radiotherapy according to an embodiment of the present disclosure may arrange, at a location not affected by a magnetic field, a phantom driving cylinder and a driving device which may move a lung mimic and a tumor mimic in a lung simulation block. The lung phantom unit may be used for general purpose even as a phantom for MRI-based and CT image-based radiotherapy. Since lung and tumor motions are implemented by air injection, it may be possible to precisely measure the motion and volume change of a lung according to subtle changes in air pressure so that customized radiotherapy suitable for a patient having various breathing patterns is possible.

  • Patent number: 11830897
    Abstract: Techniques are described for implementing a square-gate source-follower (SGSF) transistor for integration with complementary metal-oxide semiconductor (CMOS) image sensor (CIS) pixels. The SGSF transistor can have an active layer with active regions, including a drain region separated from each of two source regions to form parallel current channels. A square-gate structure layer includes main-gate regions, each disposed above a corresponding one of the current channels, and a side-gate region to couple the main-gate regions. At a particular physical width (W) and current channel length (L), the parallel current channels can act similarly to a conventional linear source-follower having dimensions of 2W and the same L. SGSF implementations can provide a number of features, including higher frame rate, lower power consumption, and lower noise, as compared to those of a conventional source-follower transistor of comparable W and L dimensions.

  • Publication number: 20230215885
    Abstract: An imaging pixel design is provide with a photo-sensor block structure that facilitates dynamic control of well capacity in the photodiode region (i.e., a “well capacity adjustment (WCA) gate photo-sensor block”). The photodiode region includes a doped well in which photocharge is accumulated responsive to exposure to incident illumination. The capacity of the well corresponds to a well potential. WCA structures (e.g., deep trench regions) form walls at least partially surrounding and capacitively coupling with the doped well, such that biasing of the WCA structures changes the well potential and the corresponding well capacity. As such, the WCA structures can be biased during integration to increase the well potential to a high level for large well capacity, and the WCA structures can be differently biased during photocharge transfer to decrease the well potential to a sufficiently low level that avoids lag and/or other conventional concerns.

The Fe-MOSFET includes source and drain regions implanted in a semiconductor substrate and separated by a channel region. The source region can be the floating diffusion region of a photosensor. A gate structure is deposited on the substrate directly above at least the channel region and an isolating layer is formed on the surface of the substrate to electrically isolate the gate structure from at least the channel region. The isolating layer is split into a Fe segment of ferroelectric material that can be written to different polarization states for conversion gain control, and a dielectric segment that can be used for current channel formation in the channel region.

  • Publication number: 20230013187
    Abstract: Techniques are described for implementing a split-select-block (split-SEL) complementary metal-oxide semiconductor (CMOS) image sensor (CIS) pixel physical architecture, such as for reducing noise in low-light application contexts. The split-SEL CIS pixel physical architecture can include a pixel block with one or more photodiodes. Above the photodiodes, there can be: a first oxide diffusion region with a reset block and a gain block disposed thereon; and a second oxide diffusion region with a select block disposed thereon. Below the photodiodes, there can be a third oxide diffusion region with a source follower (SF) block (e.g., a square-gate SF transistor) disposed thereon. A trace can be routed through the set of photodiodes to couple the source of the SF block with the select block. The architecture permits an appreciable increase in the physical gate length and/or other features.
