  • Patent number: 6620715
    Abstract: A method is provided for fabricating a device, which includes device components and spacings that may each have a final dimension that is smaller than a minimum dimension obtainable by a photolithography process used to form the device components. In particular, the method may include patterning an upper layer of the semiconductor topography using the photolithography process to form a device mask having dimensions substantially equal to or greater than the minimum dimension. The method may further include trimming the device mask and forming a semiconductor structure in alignment with the trimmed device mask. In addition, the method may include patterning the semiconductor structure to form device components and spacings therebetween. In general, patterning the semiconductor structure may include tapering a first layer of the semiconductor structure and removing an exposed portion of a second layer of the semiconductor structure.

  • Patent number: 6621184
    Abstract: A pendulum motor having a stator and a cantilever beam moveable by an electrostatic force to predetermined positions relative to a supporting structure. A micro electro mechanical system (MEMS) mechanism is formed on a semiconductor substrate using process steps that are completely compatible with current CMOS technology. A cantilever beam is fixed at one end to a structural layer and an electrode arrangement that provides an electrostatic field across a gap between the beam and a stator. A force between the beam and the stator generated by the electrostatic field results in movement of the free end of the beam relative to the stator. The free end of the beam may then be displaced by a predetermined amount from an equilibrium position and held in place by means of an applied electrostatic field. Movement of the free end of the beam is in a plane parallel to the surface of the support structure and it may follow either a circular or a non-circular path.

  • Patent number: 6618788
    Abstract: Methods and apparatus for remotely controlling an ATA device via a packet-based interface are disclosed. In one implementation, a remote host constructs command blocks corresponding to the ATA register-delivered commands that it would like executed. These command blocks are packetized and transported to a packet-to-ATA format bridge. At the bridge, each command block is parsed, and appropriate ATA read or write register commands are performed. The bridge performs requested data transfers via the packet-based interface. This embodiment can allow a non-ATAPI ATA device to connect externally to a host computer, e.g., via a USB plug-and-play packet interface. This can provide inexpensive and portable mass storage capability that does not require internal mounting or external routing of the short ATA cables that are intended for internal use only.

    Abstract: A NAND stack array (95′) is placed within a well formed on a semiconductor substrate and includes a series array of memory cell transistors (10) whose threshold voltages can be electrically altered over a range of depletion values. When a cell within a certain NAND stack is selected for a read operation, a peripheral circuit drives selected gate word line to the well potential and drives the word lines of the other gates within the selected NAND stack to a potential at least equal in magnitude to the magnitude of the a reference voltage plus the threshold voltage of a memory cell in the programmed state.

  • Patent number: 6615393
    Abstract: A method and apparatus for verification of a semiconductor device design is disclosed that includes the determination of electrical distance for shapes of a design of a semiconductor device. In the present embodiment, the method includes, for each shape to be analyzed, growing from a seed disposed within a boundary shape to be analyzed. After each new growth step, a frontier edge or a frontier polygon is generated. No frontier edges or frontier polygons result from growth steps relating to boundary shapes that have fully traversed. Therefore, as each smaller shape is traversed, growth within the traversed shape is discontinued (no frontier edges or frontier polygons result). Thus, the growth regions of smaller shapes that have been traversed drop out, and are not included in subsequent growth steps, advantageously reducing memory requirements and run-time.

  • Patent number: 6614320
    Abstract: One embodiment of the present invention is a programmable clock architecture for a microcontroller that provides multiple different clocking signal frequencies that may be utilized by one or more programmable logic blocks of the microcontroller. In this manner, the clocking architecture enables the programmable logic blocks to perform a wider variety of functions because they have access to a wider variety of clock signal frequencies. Specifically, the clocking architecture of the present embodiment includes a plurality of clocking sources. For example, the output clocking signal of one of the clock oscillators is divided down to different smaller frequencies and also multiplied to provide more frequencies that may be utilized by the programmable circuit blocks and processor of the microcontroller.
