Title: Coated inorganic powder, its production, coating agent for inorganic powder, and its production
Inventor: KATOU HANAKO
IPC: C09C1/02
Filed: 1994-12-01
Abstract: PURPOSE: To improve the surface activity of an inorg. powder by attaching an aging product obtd. by mixing an alkoxysilane oligomer with a specified amt. of water and aging the mixture and/or a diluted liq. obtd. by diluting the aging product with water or a solvent than water to an inorg. powder and drying the powder. CONSTITUTION: An oligomer is formed by partially hydrolyzing an alkoxysilane (e.g. tetramethoxysilane) by thermally reacting it with water in the presence of an acid catalyst while distilling out methanol as the by-product. The residual monomer is removed from the oligomer by vacuum distillation, etc., to a monomer content of 1wt.% or lower. The oligomer is then mixed with an acid (e.g. maleic anhydride) and water at least in an amt. enough to completely hydrolyze the oligomer and is left standing at room temp. to give an aging product. An inorg. powder (e.g. a CaCO3 powder), the aging product optionally diluted with a diluent (e.g. acetone), and if necessary, a reactive org. compd. (e.g. a silane coupling agent) are charged into a Henschel mixer and stirred under heating by passing steam, thus giving a nonfluocculated coated powder.

Title: Field effect transistor
Inventor: KANAZAWA KUNIHIKO
IPC: H01L21/338
Filed: 1988-11-25
Abstract: PURPOSE:To notably abate the noise by a method wherein a gate layer larger in specific difference than that on the other active layer is formed on the stepped part on the end of an insular epitaxial active layer on a semiconductor substrate. CONSTITUTION:A source 2 and a drain 3 are formed of an ohmic metal on an insular epitaxial substrate. A gate metal crosses over the stepped parts without growing larger by 0.2mum or more at a boundary 5. During the gate formation process, a resist is apt to become thinner on the boundary 5 getting over-exposed to make a gate pattern larger. Accordingly, in a low noise high electron transfer rate transistor with a gate e.g., in size of 0.3mum, a mask pattern in size of 0.3mum is to be made larger by +0.2mum due to the thickness of the resist. In such a constitution, the thickness of the resist layer at the stepped part can be regulated at the maximum size of 0.2mum by using the resist in thickness 2-3 times of that of the epitaxial active layer 4 so that the gate may not be disconnected at the stepped part.
