    摘要: In a semiconductor device with a trench-type element isolation structure, alignment can be performed with high accuracy without any deterioration in device performance. The surfaces of silicon oxide films (2B, 2C) embedded in trenches (10B, 10C) of an element forming region including a memory cell region (11B) and a peripheral circuit region (11C) in a semiconductor substrate (1), respectively, are almost level with the surface of the semiconductor substrate (1). On the other hand, the surface of a silicon oxide film (2A) embedded in a trench (10A) is formed lower than the surface of the semiconductor substrate (1).

    摘要: In forming an element isolating region in a silicon semiconductor layer of an SOI substrate, a silicon nitride film of a predetermined thickness is deposited over an oxide film formed on a SOI layer. The silicon nitride film is patterned in a design size of active regions, and side walls of a silicon nitride film are formed on the side surfaces of the patterned silicon nitride film. A first LOCOS process is carried out using the nitride film as an oxidation mask. A LOCOS film formed by the first LOCOS process is removed to form narrower concavities under the side walls. Then, another silicon nitride film is deposited, and is removed leaving portions thereof forming the concavities. Then, a second LOCOS process is carried out to form a LOCOS film as an element isolating region. The second LOCOS process uses the oxidation mask having the narrow cavities, so that stress at the boundary of the active region and the element isolation region is reduced, and the growth of bird's beaks can be suppressed.

    摘要: The bacterium Sphingobacterium multivorum has been cultivated to produce a deaminoneuraminidase which is specific for catalyzing the hydrolysis of the ketosidic linkage formed by deaminoneuraminic acid in complex carbohydrates. The deaminoneuraminidase does not catalyze the hydrolysis of either the ketosidic linkage formed by N-acetylneuraminic acid or the ketosidic linkage formed by n-glycolylneuraminic acid and complex carbohydrates.

    摘要: It is an object to obtain a semiconductor device with the LDD structure having both operational stability and high speed and a manufacturing method thereof. A high concentration region (11) with boron of about 1.times.10.sup.18 /cm.sup.3 introduced therein is formed extending from under a channel formation region (4) to under a drain region (6) and a source region (6') in a silicon substrate (1). The high concentration region (11) is formed in the surface of the silicon substrate (1) under the channel formation region (4), and is formed at a predetermined depth from the surface of the silicon substrate (1) under the drain region (6) and the source region (6'). A low concentration region (10) is formed in the surface of the silicon substrate (1) under the drain region (6) and the source region (6'). The formation of the high concentration region only in the surface of the semiconductor substrate under the channel formation region surely suppresses an increase in the leakage current and an increase in the drain capacitance.

    摘要: A storage controller comprising a storage device adapter, a channel adapter, a cache memory, a control memory, and a plurality of buses connecting therebetween. The channel adapter communicates with a processor and processes input/output requests issued by the processor. The storage device adapter controls a storage device and data transfer between the storage device and the cache memory. The channel adapter and the storage device adapter exchanges control information via the control memory. The buses are used to transfer the data and the control information between the cache memory and the control memory, and the channel adapter and the storage device adapter. The controller also comprises bus load estimating means and bus mode selecting means. The bus load estimating means estimates bus load characteristics as an index based on the amount of data transfer during sequential access to the storage device. The bus mode selecting means determines a bus mode of bus utilization based on the index. Each of the channel adapter and the storage device adapter has bus access means for accessing the buses in accordance with the bus mode selected by the bus mode selecting means.

    摘要: Potassium hexatitanate fibers having a tunnel structure and a free potassium content of 5 ppm or less can be produced by mixing together a titanium containing compound and a potassium containing compound in a ratio represented by the formula K.sub.2 O.nTiO.sub.2 (wherein n=from 2 to 4); firing the mixture at 900.degree. to 1,200.degree. C. to produce mass of potassium titanate fibers; dipping the mass of product in either cold or hot water to disintegrate the mass of potassium titanate fibers into individual single fibers; adding an acid to the slurry to adjust the pH value to 9.3-9.7, thereby changing the composition of the potassium titanate fibers so that the molar ratio of TiO.sub.2 /K.sub.2 O is in the range of from 5.95 to 6.00; heating the fibers at 950.degree. to 1,150.degree. C. for 1 hour or more; and washing the fibers with an acid. The potassium hexatitanate fibers, which have a minimal free potassium content, i.e., 5 ppm or less, can be suitably used as a reinforcing material for polyester thermoplastic resins, polyphenylene sulfide resins, liquid crystal polymers, aluminum alloys, magnesium alloys and so forth, all of which are easily affected by free potassium.
