    摘要： An improved method of forming a semiconductor device is described. In that method, a dielectric layer that comprises a carbon doped oxide is formed on a substrate. After a first etched region is formed in the dielectric layer, that region is filled with a sacrificial light absorbing material. A layer of photoresist is then deposited and patterned, followed by forming a second etched region by removing part of the sacrificial light absorbing material and a second part of the dielectric layer. Remaining portions of the photoresist are then removed by exposing the resulting device to a plasma generated from a forming gas. The device is then exposed to a solution for removing the remaining portions of the sacrificial light absorbing material.

    摘要： The maize gene dull1 (du1) of the present invention is a determinant of the structure of endosperm starch. Mutations of du1 affect the activity of at least two enzymes involved in starch biosynthesis, namely the starch synthase, SSII, and the starch branching enzyme, SBEIIa. Du1 codes for a predicted 1674 residue protein, and is expressed with a unique temporal pattern in endosperm but is undetectable in leaf or root. The size of the Du1 product and its expression pattern match precisely the known characteristics of maize SSII. The Du1 product contains two different repeated regions in its unique amino terminus, one of which is identical to a conserved segment of the starch debranching enzymes. The cDNA provided for in the present invention encodes SSII, and mutations within this gene affect multiple aspects of starch biogenesis by disrupting an enzyme complex containing starch synthase(s), starch branching enzyme(s), and possibly starch debranching enzyme(s).

    摘要： SHE, a Starch Hydrolytic Enzyme active in maize endosperm (Zea mays), and the cDNA sequence encoding SHE are disclosed. The specificity of native, purified SHE is similar, in general terms, to previously known alpha-amylases. However, the activity of SHE toward amylopectin results in hydrolysis products that are distinctly different from those of other alpha-amylases. SHE, and its homologous equivalents in other plants such as rice, Arabidopsis, apple and potato, can be used in starch processing for generating different, e.g., larger sized, alpha-limit dextrins for industrial use, as compared to those generated by previously known alpha-amylases or other starch hydrolytic enzymes. In addition, modification of the expression of this enzyme in transgenic maize plants or in other transgenic organisms (including bacteria, yeast, and other plant species) can be useful for the generation of novel starch forms or altered starch metabolism.

    摘要： SU1, a starch debranching enzyme active in maize endosperm (Zea mays), and the cDNA and genomic sequences encoding SU1 are disclosed. The amino acid sequence is significantly similar to that of bacterial isoamylases, enzymes that hydrolyze α-(1→6) glycosidic bonds. Amino acid sequence similarity establishes SU1 as a member of the α-amylase superfamily of starch hydrolytic enzymes. Also disclosed are antibodies reactive with the SU1 protein, methods of producing antibodies to the SU1 protein, methods of producing fusion proteins including SU1 as well as recombinant SU1 and methods of producing transgenic plants with a modified Su1 gene. The native or expressed SU1 protein can serve as a replacement for the bacterial and fungal enzymes currently used in the starch processing industry.
