摘要:
It is an object of the present invention to effectively manufacture a charged-particle beam lithography mask, an X-ray lithography mask, or an extreme ultraviolet beam lithography mask by using, for example, an existing writer such as an electron beam writer for photomasks, while achieving improvement in processing accuracy of a mask pattern. A lithography mask (1) comprises a substrate (2) which has a lower surface provided substantially at the center thereof with an opening (3) and a self-supporting membrane (m) having a pattern region (4) substantially at the center of an upper surface of the substrate (2) corresponding to the opening (3). The self-supporting membrane (m) is provided with through-holes (h) of a mask pattern in it or an absorber or scatterer of a mask pattern on it, and the pattern region (4) and a peripheral region around the pattern region (5) are in one plane.

A combined AD/DA converting apparatus carrying out AD conversion of an analog input signal to output a converted digital signal or carrying out DA conversion of a digital input signal to output a converted analog signal based on a conversion selection signal for selecting AD conversion or DA conversion comprises an input signal selection circuit configured to select one analog signal out of a plurality of analog input signals to be output based on an input selection signal; an input sample hold circuit configured to sample and hold the analog input signal output from the input signal selection circuit; a DA converter configured to convert a digital signal into an analog signal to be output; a comparator circuit configured to output a comparison signal that indicates a size relation between the analog input signal output from the input sample hold circuit and the analog signal output from the DA converter; a sequential comparison register configured to define sequentially each place of a digital signal stored in the register based on the comparison signal output from the comparison circuit; a selection circuit configured to receive the digital signal stored in the sequential comparison register, the digital input signal, and the conversion selection signal, the selection circuit being configured to output the digital signal stored in the sequential comparison register to the DA converter when the conversion selection signal indicates AD conversion, and to output the digital input signal to the DA converter when the conversion selection signal indicates DA conversion; and a controlling unit configured to output the input selection signal when the conversion selection signal indicates DA conversion.
摘要:
A clustering disk subsystem comprising a switch holding a table which can modify a destination of a request from a host computer, wherein the switch transfers an access request to another channel according to a destination channel status such as heavy load or fault, and the channel which received the request processes the request by proxy for load balancing between internal disk controllers in a clustering disk subsystem. The subsystem has an effect in which load balancing or fail-over between channels or disk controllers can be performed without any special hardware or software in the host. As a result, good performance can be obtained even when access requests from the host computer are concentrated in a specific channel or disk controller.
