摘要:An automatic wafer inspection system (10) having a wafer storage and loading module (18) and a wafer storage and unloading module (20), transports a wafer (15) to and from an automated stage (16) that moves the wafer (15) under a microscope (17) for scanning. A sensing device (12) images the area of the wafer (15) under inspection. A processing unit (22), having a host computer (21), multiple controllers (23), a high speed image processing unit (25), and a power supply (27), controls the scanning of the wafer and performs the image decomposition, synthesis and image processing (Fig. 2) for automatic inspection. A computer (21), decomposes the raw image data (26) into a set of partial information channels having command spatial relations (35). Each channel reflects predetermined aspects of the information. The partial information can thus be processed using image processing techniques independently or cooperatively. Partial information images may be synthesized (Fig. 7) to recover the original image or to derive an improved image for automation inspection. The system acquires an image (24), performs an image decomposition (26) on the image to generate a decomposition data set (35) of spatial frequency and orientation bandpass component images that represent the decomposition of the input image (26), performs multiple channel feature detection and enhancement on the decomposition data set (28), performs image synthesis (30) and defect detection (32).

摘要:A method for producing a polysaccharide ester microsphere may include forming a polysaccharide ester product from a polysaccharide synthesis, wherein the polysaccharide ester product comprises a polysaccharide ester and a solvent; diluting the polysaccharide ester product, thereby yielding a polysaccharide ester dope; and forming a plurality of polysaccharide ester microspheres from the polysaccharide ester dope. Suitable polysaccharides may include, but are not limited to, starch, cellulose, hemicellulose, algenates, chitosan, and any combination thereof. Esters thereof may be organic esters (e.g., acetate and the like), inorganic esters (e.g., sulfonates and the like), or combinations thereof. Further, the solids conent of the polysaccharide ester dope, in some instances, may be greater than about 16 wt %.
