Disclosed are techniques and apparatus are provided for determining overlay error or pattern placement error (PPE) across the field of a scanner which is used to pattern a sample, such as a semiconductor wafer or device. This determination is performed in-line on the product wafer or device. That is, the targets on which overlay or PPE measurements are performed are provided on the product wafer or device itself. The targets are either distributed across the field by placing the targets within the active area or by distributing the targets along the streets (the strips or scribe areas) which are between the dies of a field.

Improved method of encoding and repairing data for reliable storage and transmission using erasure codes, which is efficient enough for implementation in software as well as hardware. A systematic linear coding matrix over GF(2q) is used which combines parity for fast correction of single erasures with the capability of correcting k erasures. Finite field operations involving the coding and repair matrices are redefined to consist of bitwise XOR operations on words of arbitrary length. The elements of the matrix are selected to reduce the number of XOR operations needed and buffers are aligned for optimal processor cache efficiency. Decode latency is reduced by pre-calculating repair matrices, storing them in a hashed table and looking them up using a bit mask identifying the erasures to be repaired.

When any signal addressed to the self station is contained, the control channel signal is cancelled from the reception signal in accordance with a wireless channel quality and the traffic channel is demodulated.

A technique to verify, evaluate, and estimate the performance of an integrated circuit is embodied in a computer software program that is executable by a computer system. The technique accurately estimates of the performance (e.g., transient delays) of an integrated circuit, and has fast execution times. The technique includes an incremental recharacterization feature where only portions of the design which have been changed or are new or different will need to be recharacterized during subsequent runs of the software. Portions of the design which are the same need not be recharacterized, and results for those portions from a previous run (stored in a database) are used. This saves execution time since the performance recharacterization or evaluation process is generally more time consuming than a database look up. The technique is applicable to small circuits having relatively few transistors, and especially well suited for integrated circuits having millions of transistors and components. The technique handles the effects of deep-submicron integrated circuit technology.
