Abstract: Methods of semiconductor processing are described. An experiment is designed for each process of a semiconductor substrate, which are implemented on respective multiple regions of the semiconductor substrate. A unique identifier is assigned to the semiconductor substrate. The respective design of experiment is implemented for each of the processes of the semiconductor substrate. Process criteria for each process is recorded, where the recording is associated with the assigned unique identifier. Process information is retrieved for each process, via its respective assigned unique identifier.

Abstract: A backplane having a layer of insulation material, a plurality of lead segments arranged in line and spaced from one another on a first surface of the insulation material, a plurality of cooperating lead segments arranged in line and spaced from one another on a second surface of the insulation material, and connectors for interconnecting the ends of alternate segments on the first and second surfaces to form a first continuous line alternating between lead segments on the first and second surfaces. Connectors are also provided for connecting the ends of alternate segments on the first and second surfaces to form a second continuous line separate from the first line, the first and second lines twisting along the axis of signal propagation to produce a twisted pair in the backplane.

Abstract: An automatic dialer for controlling access to a long-distance telephone network. The automatic dialer includes a read/write memory. Each time the user attempts to call through the network a telephone number inaccessible via the network, an entry representing the area code and/or exchange of that telephone number is made in the memory. Prior to calling the network, the dialer compares the destination telephone number with the entries in the memory; the call is placed via the network only if the area code and exchange of the destination number do not match any of the entries. The entries in the memory are ordered according to recency of attempts by the user to access a telephone number within the groups of telephone numbers represented by the entries; when the memory is filled, the oldest entry is deleted to make room for the newest entry.
