Abstract: A modified nucleoside or nucleotide, the 3?-OH of the modified nucleoside or nucleotide being reversibly blocked; meanwhile, the present invention also relates to a kit comprising the nucleoside or nucleotide, and a sequencing method based on the nucleoside or nucleotide.

Abstract: A method of manufacturing a semiconductor device includes the following steps. A device wafer having a product-obtaining part and an edge part surrounding the product-obtaining part is provided. A passivation layer is formed to cover the device wafer. A first oxide cap layer is formed to cover the passivation layer. An edge trimming process is performed to polish an edge part of the first oxide cap layer, an edge part of the passivation layer and the edge part of the device wafer. A removing process is performed to remove the first oxide cap layer after the edge trimming process is performed. A second oxide cap layer is formed to cover the first oxide cap layer and the edge part of the device wafer.

Abstract: An apparently seamless lengthened bamboo sheet is formed by lengthening a plurality of bamboo strips or blanks and assembling a plurality of lengthened bamboo strips or blanks together. A slot is formed on at least one end of the bamboo strips or blanks in direction of length, and a tenon corresponding to the slot is formed on the same end; the tenon on one bamboo strip or blank is embedded into the slot on another bamboo strip or blank. The tenon and slot are mutually matched and the two bamboo strips or blanks are engaged to each other. A method to manufacture is the apparently seamless lengthened bamboo sheet includes: forming a slot and a tenon on the end of bamboo strips or blanks; embedding a tenon at one end of one bamboo strip or blank into a slot on one end of another bamboo strip or blank; assembling and gluing a plurality of lengthened bamboo strips or blanks in direction of width or thickness; forming the bamboo sheet by a common process including pressing.
