Abstract: In one aspect, the invention encompasses a method of forming a semiconductor device. A masking material is formed over a semiconductor substrate. A mold is provided, and the mold has a first pattern defined by projections and valleys between the projection. The masking material is pressed between the mold and the substrate to form a second pattern in the masking material. The second pattern is substantially complementary to the first pattern. The mold is removed from the masking material, and subsequently the masking material is utilized as a mask during etching of the semiconductor substrate. In another aspect, the invention encompasses a method of forming a field emission display. A first material layer is formed over a conductive substrate, and a masking material is formed over the first material layer. A mold is provided over the mask material, and the mask material is pressed between the mold and the first material layer to pattern the masking material. The pattern is transferred from the masking material to the first material layer. The patterned first material layer is then used as a second mask, and the conductive substrate is etched to form a plurality of conically shaped emitters. A display screen is formed in a spaced relation to such emitters.

Abstract: A hexagonal mold is formed by a unitary base and a unitary cover. Each of the base and the cover form three of the six surfaces of a hexagonal mold cavity when the cover is placed on top of the base. The hexagonal mold may be used to form field emission display spacers and field emission display microchannels by placing etchable single fibers in the hexagonal mold to form hexagonal multiple fiber preforms. The preforms are then drawn to form multiple fibers that are placed in a rectangular mold to form a rectangular fiber block. The rectangular fiber block is then sliced into sheets which are then placed between a field emission display baseplate and a field emission display faceplate.

Abstract: Communications equipment can be tested using a test pattern that is modified compared to, and more exploitive than, a standard test pattern. Test patterns can be employed that have lengthened or shortened consecutive identical digit (CID) portions, or that have lengthened or shortened pseudo random bit sequence (PRBS) portions. In some cases, PRBS polynomials are not re-seeded after each CID. Further, different order polynomials can be employed for different applications. Exemplary applications can include test equipment and built-in self-test capability for integrated circuits.

Abstract translation: 通信设备可以使用与标准测试模式相比修改的测试模式进行测试，并且比标准测试模式更具有潜力。 可以采用具有延长或缩短连续相同数字（CID）部分或具有延长或缩短的伪随机位序列（PRBS）部分的测试模式。 在某些情况下，在每个CID之后，PRBS多项式不再重播。 此外，不同的阶多项式可以用于不同的应用。 示例性应用可以包括测试设备和用于集成电路的内置自检能力。
