  • Patent number: 9337262
    Abstract: The present application provides (in addition to more broadly applicable inventions) improvements which are particularly applicable to two-sided power semiconductor devices which use bipolar conduction. In this class of devices, the inventor has realized that two or three of the four (or more) semiconductor doping components which form the carrier-emission structures and control structures in the active device (array) portion of a two-sided power device can also be used, with surprising advantages, to form field-limiting rings around the active arrays on both surfaces. Most preferably, in some but not necessarily all embodiments, a shallow implant of one conductivity type is used to counterdope the surface of a well having the other conductivity type. This shallow implant, singly or in combination with another shallow implant of the same conductivity type, works to shield the well from the effects of excess charge at or above the surface of the semiconductor material.

  • Patent number: 9331166
    Abstract: Angled directional ion beams are directed to sidewalls of a gate structure that straddles at least one semiconductor fin. The directions of the angled directional ion beams are contained within a vertical plane that is parallel to the sidewalls of the at least one semiconductor. A pair of gate spacers are formed on sidewalls of the gate structure by accumulation of the deposited dielectric material from the angled directional ion beams and without use of an anisotropic etch, while the sidewalls of the semiconductor fins parallel to the directional ion beams remain physically exposed. A selective epitaxy process can be performed to form raised active regions by growing a semiconductor material from the sidewalls of the semiconductor fins.

  • Patent number: 9305930
    Abstract: A flash memory device in a dual fin single floating gate configuration is provided. Semiconductor fins are formed on a stack of a back gate conductor layer and a back gate dielectric layer. Pairs of semiconductor fins are formed in an array environment such that shallow trench isolation structures can be formed along the lengthwise direction of the semiconductor fins within the array. After formation of tunneling dielectrics on the sidewalls of the semiconductor fins, a floating gate electrode is formed between each pair of proximally located semiconductor fins by deposition of a conformal conductive material layer and an isotropic etch. A control gate dielectric and a control gate electrode are formed by deposition and patterning of a dielectric layer and a conductive material layer.

  • Patent number: 9299702
    Abstract: A transistor structure having an epitaxial layer deposited over an implanted substrate in order to reduce process variability. The epitaxial layer is able to be deposited doped, un-doped or lightly doped via up-diffusion from the implanted substrate, and used to form the channel for the transistor structure. As a result, this use of un-doped epitaxial layer provides the benefit of reducing process variability (e.g. random dopant fluctuation) and thus the transistor performance variability despite the small physical size of the transistors.

  • Patent number: 9257581
    Abstract: The present disclosure relates to a back-side illuminated CMOS image sensor (BSI CIS). In some embodiments, the BSI CSI has a semiconductor substrate with a front-side and a back-side. A plurality of photodetectors are located within the front-side of the semiconductor substrate. An implantation region is located within the semiconductor substrate at a position separated from the plurality of photodetectors. The implantation region is disposed below the plurality of photodetectors and has a non-uniform doping concentration along a lateral plane parallel to the back-side of the semiconductor substrate. The non-uniform doping concentration allows for the BSI CSI to achieve a small total thickness variation (TTV) between one or more photodetectors and a back-side of a thinned semiconductor substrate that provides for good device performance.

    Abstract: An image sensor operable in global shutter mode ma include small pixels with high charge storage capacity, low dark current, and no image lag. Storage capacity of a photodiode and a charge storage diode may be increased by placing a p+ type doped layer under the photodiode and the charge storage diode. The p+ type doped layer ma include an opening for allowing photo-generated charge carriers to flow from the silicon bulk to the charge storage well located near the surface of the photodiode. A compensating n? type doped implant may be formed in the opening. Image lag is prevented by placing a p? type doped region under the p+ type doped photodiode pinning layer and aligned with the opening. The p+ type doped layer may extend under the entire pixel array.
