  • Publication number: 20120228579
    Abstract: A semiconductor p-i-n diode and method for forming the same are described herein. In one aspect, a SiGe region is formed between a region doped to have one conductivity (either p+ or n+) and an electrical contact to the p-i-n diode. The SiGe region may serve to lower the contact resistance, which may increase the forward bias current. The doped region extends below the SiGe region such that it is between the SiGe region and an intrinsic region of the diode. The p-i-n diode may be formed from silicon. The doped region below the SiGe region may serve to keep the reverse bias current from increasing as result of the added SiGe region. In one embodiment, the SiGe is formed such that the forward bias current of an up-pointing p-i-n diode in a memory array substantially matches the forward bias current of a down-pointing p-i-n diode which may achieve better switching results when these diodes are used with the R/W material in a 3D memory array.

  • Patent number: 8067277
    Abstract: An active matrix pixel device is provided, for example an electroluminescent display device, the device comprising circuitry supported by a substrate and including a polysilicon TFT (10) and an amorphous silicon thin film PIN diode (12). Polysilicon islands are formed before an amorphous silicon layer is deposited for the PIN diode. This avoids the exposure of the amorphous silicon to high temperature processing. The TFT comprises doped source/drain regions (16a,17a), one of which (17a) may also provide the n-type or p-type doped region for the diode. Advantageously, the requirement to provide a separate doped region for the photodiode is removed, thereby saving processing costs. A second TFT (10b) having a doped source/drain region (16b,17b) of the opposite conductivity type may provide the other doped region (16b) for the diode, wherein the intrinsic region (25) is disposed laterally between the two TFTs, overlying each of the respective polysilicon islands.

  • Patent number: 8067308
    Abstract: A semiconductor device has a conductive via formed through in a first side of the substrate. A first interconnect structure is formed over the first side of the substrate. A semiconductor die or component is mounted to the first interconnect structure. An encapsulant is deposited over the first interconnect structure and semiconductor die or component. A portion of a second side of the substrate is removed to reduce its thickness and expose the TSV. A second interconnect structure is formed over the second side of the substrate. The encapsulant provides structural support while removing the portion of the second side of the substrate. The second interconnect structure is electrically connected to the conductive via. The second interconnect structure can include a redistribution layer to extend the conductivity of the conductive via. The semiconductor device is mounted to a printed circuit board through the second interconnect structure.

  • Patent number: 8034716
    Abstract: Semiconductor structures and methods of making a vertical diode structure are provided. The vertical diode structure may have associated therewith a diode opening extending through an insulation layer and contacting an active region on a silicon wafer. A titanium silicide layer may be formed over the interior surface of the diode opening and contacting the active region. The diode opening may initially be filled with an amorphous silicon plug that is doped during deposition and subsequently recrystallized to form large grain polysilicon. The silicon plug has a top portion that may be heavily doped with a first type dopant and a bottom portion that may be lightly doped with a second type dopant. The top portion may be bounded by the bottom portion so as not to contact the titanium silicide layer. In one embodiment of the vertical diode structure, a programmable resistor contacts the top portion of the silicon plug and a metal line contacts the programmable resistor.
