In this paper, we propose a novel methodology for detecting systematic spatial failure patterns at wafer level for yield learning. Our proposed methodology takes the testing results (i.e., pass or fail) of a number of dies over different wafers, cluster all these wafers according to their failures, and eventually identify the underlying spatial failure patterns. Several novel machine learning algorithms, including singular value decomposition, hierarchical clustering, dictionary learning, etc., are developed in order to make the proposed methodology robust to random failures. The efficacy of our proposed approach is demonstrated by an industrial data set.

Identifying systematic spatial failure patterns through wafer clustering

Three algorithms are developed for the compression of one-dimensional data by loosely coupled cubic splines. spline knots are located by adaptive iterative searches. The methods are applied to the compression of profile retrieval coefficients obtained from NOAA radiosonde/radiometric data. Additional compression is achieved by error acceptable, significant figure rounding, coupled with storage in integer strings. The results are compared with compression by finite-length discrete Fourier series computed by FFT procedures.
