  • Patent number: 10163476
    Abstract: A method of operating a tracking circuit of a memory device includes charging a node of the tracking circuit to a first predetermined voltage level, the first node being electrically coupled with a first load device. A first plurality of tracking cell transistors are activated to discharge the first node toward a second predetermined voltage level. A reset signal is generated based on a signal at the first node. The reset signal may correspond to a waiting period for reading a memory cell of the memory device.

  • Patent number: 10156783
    Abstract: A system and method for repairing a photolithographic mask is provided. An embodiment comprises forming a shielding layer over an absorbance layer on a substrate. Once the shielding layer is in place, the absorbance layer may be repaired using, e.g., an e-beam process to initiate a reaction to repair a defect in the absorbance layer, with the shielding layer being used to shield the remainder of the absorbance layer from undesirable etching during the repair process.

  • Patent number: 9666520
    Abstract: Disclosed herein is a package comprising a first die having a first redistribution layer (RDL) disposed on a first side of a first substrate and a second die having a second RDL disposed on a first side of a second substrate, with the first RDL bonded to the second RDL. A third die having a third RDL is disposed on a first side of a third substrate, the third die mounted over the second die, with the second die disposed between the first die and the third die. First vias extend through, and are electrically isolated from, the second substrate, with the first vias each contacting a conductive element in the first RDL or the second RDL. Second vias extend through, and are electrically isolated from, the third substrate, with the second vias each contacting a conductive element in the third RDL or one of the first vias.

  • Patent number: 9660033
    Abstract: A method of semiconductor device fabrication includes providing a fin extending from a substrate and having a source/drain region and a channel region. The fin includes a first layer, a second layer over the first layer, and a third layer over the second layer. A gap is formed by removing at least a portion of the second layer from the channel region. A first material is formed in the channel region to form first and second interfacial layer portions, each at least partially wrapping around the first and third layers respectively. A second material is deposited in the channel region to form first and second high-k dielectric layer portions, each at least partially wrapping around the first and second interfacial layer portions. A metal layer including a scavenging material is formed along opposing sidewalls of the first and second high-k dielectric layer portions in the channel region.

  • Patent number: 9236856
    Abstract: An apparatus for controlling slew rate is coupled to two adjustable voltage rails. The output of the apparatus is coupled to the gate of a switching element. By employing two adjustable voltage rails, the slew rate of the switching element is proportional to the voltage difference between the first adjustable rail and the second adjustable rail. The slew rate control apparatus can be applied to a variety of switching elements including N channel Field Effect Transistors (NFETs), P channel Field Effect Transistors (PFETs), current mode logic circuits and level shifter circuits.

  • Publication number: 20150145579
    Abstract: A circuit includes a first circuit, a second circuit and a third circuit. The first circuit is configured to receive a first phase of a clock signal, a second phase of a clock signal and a first control signal. The first circuit is configured to generate a first interpolated phase of a clock signal. The second circuit is configured to receive a third phase of a clock signal, a fourth phase of a clock signal and a second control signal, and generate a second interpolated phase of a clock signal. The third circuit is configured to receive the first interpolated phase of the clock signal and the second interpolated phase of the clock signal, and generate the first control signal. The first control signal dynamically adjusts the first interpolated phase of the clock signal.
