An aliphatic polyester film on which an inorganic gas-barrier film is formed by deposition to improve the gas barrier properties of the aliphatic polyester wherein the adhesion between the aliphatic polyester film and the deposited gas-barrier film has been improved. The aliphatic polyester film is biaxially stretched and comprises at least two layers (layers A and B). Each of the layers A and B contain an amorphous polylactic acid resin and a crystalline polylactic acid resin in a predetermined ratio.

An adhesive tape comprises a base sheet of a polypropylene resin, an adhesive layer formed on one side of the base sheet and a roughened surface layer formed on the other side of the base sheet and composed of a polypropylene resin containing fine inorganic filler particles, in which the roughened surface layer has a thickness of not more than the maximum particle diameter of said fine inorganic filler particles and is substantially free from voids or cracks, and the total percent light transmittance of the tape is at least 90%. Such an adhesive tape is produced by a process which comprises forming an adhesive layer on one side of a base sheet of a polypropylene resin and a surface layer of a polypropylene resin having a melting point lower than that of the polypropylene resin of the base sheet and containing fine inorganic filler particles, on the other side of the base sheet to obtain an unstretched laminated sheet, and then stretching the laminated sheet at a temperature of at least the melting point of the polypropylene resin of the surface layer to bring the thickness of the surface layer to be not more than the maximum particle diameter of said fine inorganic filler particles.

The present invention provides a linear pattern detection method which can extract and detect linear patterns distinguished by a microscopic defect distribution profile even if skipped measurements are taken. The linear pattern detection method acquires a defect map created based on results of defect inspection of a wafer; divides the defect map into a plurality of first segments; calculates a correlation coefficient of a point sequence in each of the first segments, the point sequence corresponding to a defect group contained in the first segments; calculates a total number of those first segments in which the correlation coefficient is equal to or larger than a first threshold; and determines that the wafer contains a linear pattern if the total number is equal to or larger than a second threshold.
