  • Patent number: 7569857
    Abstract: Embodiments of the invention provide a substrate with a device layer having different crystal orientations in different portions or areas. One layer of material having one crystal orientation may be bonded to a substrate having another crystal orientation. Then, a portion of the layer may be amorphized and annealed to be re-crystallized to the crystal orientation of the substrate. N- and P-type devices, such as tri-gate devices, may both be formed on the substrate, with each type of device having the proper crystal orientation along the top and side surfaces of the claimed region for optimum performance. For instance, a substrate may have a portion with a <100> crystal orientation along a top and sidewalls of an NMOS tri-gate transistor and another portion having a <110> crystal orientation along parallel top and sidewall surfaces of a PMOS tri-gate transistor.

  • Patent number: 7560775
    Abstract: In a transistor of the invention, at a boundary between gate oxide 112 formed on a silicon substrate 101 of a device formation region 10 and a device isolation film 110 adjoining the gate oxide 112, a thickness D? of the gate electrode 114 is set larger than a uniform thickness D of the gate electrode 114 on the gate oxide 112. A height difference A between a surface of the gate oxide 112 and a surface of the device isolation film 110, a width B of a step portion 110b of the device isolation film, and the thickness D of the gate electrode 114 in its uniform-thickness portion satisfy relationships that D>B and A/D+(1?(B/D)2)0.5>1. By ion implantation via the gate electrode 114 and the gate oxide 112, an impurity is added into a surface portion of the silicon substrate 101 at an end portion 11 of the device formation region, the impurity having concentrations higher than in the surface portion of the silicon substrate 101 in the electrode uniform portion 12 of the device formation region.

  • Patent number: 7561223
    Abstract: A resist region covering the gate terminal and lead and between a passivation layer and a gate insulating layer is used to protect the gate terminal and lead. The resist region is located at a scribing line on margin of the color filter substrate of a panel, thereby the resist region can protect the passivation layer and the gate insulating layer from cracking, and the gate terminal and the lead from corrosion after a portion of the color filter substrate is removed along the scribing line.

  • Patent number: 7550793
    Abstract: The image pickup device of the invention has a path deeper in a semiconductor substrate, than a region wherein a channel is formed, upon turning on a first MOS transistor, under a gate thereof. The path is arranged by forming a P-type layer for forming a potential barrier, within a P-type well excluding a region below the gate of the first MOS transistor. Thus, even when the first transfer MOS transistor is securely turned off at accumulation, carriers overflowing from a photodiode can flow into the path, thereby enabling to accumulate the carriers, overflowing from the photodiode, in a carrier accumulation region. Such structure allows to suppress a dark current generation from an interface of a gate oxide film of the first transfer MOS transistor, and also to expand the dynamic range of the image pickup device by the carriers overflowing from the photodiode and flowing through the path into the carrier accumulation region.

  • Patent number: 7514727
    Abstract: A unit HBT and a unit FET are arranged to be adjacent to each other through an isolation region and a base electrode of the unit HBT is connected to a source electrode of the unit FET to form a unit element, and a plurality of unit elements are connected to form an active element. This makes it possible to implement the active element in which a current is not likely to concentrate on the unit element and no destruction is generated by the second breakdown. Moreover, although a buried gate electrode structure is used to ensure a withstand pressure in the unit FET, a buried portion is structured not to be diffused to an InGaP layer, and thereby it is possible to prevent Pt from being abnormally diffused. Furthermore, a selection etching can be used for a formation of an emitter mesa, that of a base mesa, that of a ledge in the unit HBT, and a gate recess etching in the unit FET, and a good reproducibility can be obtained.
