    摘要: A defect management system with a method to update a database with defect data concerning propagator defect data. Defect data obtained from each layer formed on a semiconductor wafer is stored in a relational database. Defect data determined in a current layer to be defect data for a defect observed in a previous layer is defined as data concerning a propagator defect. Propagator defect data is used to update the data in the database relating to the previous layer.

    摘要: A semiconductor wafer optical scanning system and method for determining defects on a semiconductor wafer is disclosed. The method for determining wafer defects is based on maximum allowable defects on a swath basis, rather than maximum allowable defects on a wafer basis. The method step include determining the scanned area of an individual swath that is based on a recipe set-up, consistent with the capability of the optical scanning equipment being used and the particular semiconductor wafer being tested for defects. The predetermined swath area is supplied and stored in the optical scanning system along with the maximum allowable defect density determined by the user. By using the predetermined maximum allowable defects for a swath as a limit, defect analysis may be performed on the entire wafer. The optical scanning system would stop acquiring defects for the current swath being analyzed whenever the defect limit is reached, or until the swath defect analysis has been completed. The optical scanning would proceed to the next swath determining its defect and continuing in such a manner until the wafer is completely scanned.

    摘要: An ultra-large scale CMOS integrated circuit semiconductor device with LDD structures having gradual doping profiles and reduced process complexity is manufactured by forming a gate oxide layer over the semiconductor substrate; forming a polysilicon layer over the gate oxide layer; forming a first mask layer over the polysilicon layer; patterning and etching the first mask layer to form a first gate mask; anisotropically etching the polysilicon layer to form a first polysilicon gate, wherein the first polysilicon gate has sidewalls with sloped profiles and the sloped profiles are used as masks during the ion implantation of the LDD structures to space the resultant LDD structures away from the edges of second polysilicon gates to be formed subsequently with substantially vertical profiles. Since the LDD structures are spaced away from the edges of the second polysilicon gates, the lateral diffusion of the LDD structures into the channel due to rapid thermal annealing is reduced.
