Title: Silicon nitride sintered body
Inventor: HASHIMOTO SEIJI
IPC: C04B35/626
Filed: 1987-11-09
Abstract: PURPOSE:To obtain a silicon nitride sintered body which is improved in strength and fracture toughness by sintering Si3N4 powder which contains a specific ratio of Ca and is not added with a sintering assistant. CONSTITUTION:This silicon nitride sintered body is obtd. by sintering the silicon nitride powder which contains, by weight, 100-1,000ppm calcium and is not added with the sintering assistant. The Si3N4 powder which contains the Ca at a low ratio and is obtd. by a direct reaction method, imide thermal decomposition method, SiO2 reduction method, etc., is used. The other impurities in the Si3N4 powder, for example, metal impurities such as Fe, Al, Mn and Ni and impurities such as C and Cl may be incorporated therein within the range where the properties are not degraded. The lower ratios thereof are more preferable. The Ca is preferably added to the Si3N4 powder in the form of, for example, oxide CaO. This silicon nitride sintered body is not added with the assistants as an auxiliary effect, unlike with the conventional sintered bodies, and therefore, the oxidation of the sintered body by the exudation of such assistants on the surface is obviated and the oxidation resistance is improved.

Title: Field-effect transistor structure
Inventor: KITSUTO MAN CHIYAN
IPC: H01L29/06
Filed: 1987-11-09
Abstract: PURPOSE:To manufacture a small-sized and high-speed MOSFET by a method wherein a short channel effect and a junction capacitance effect are reduced simultaneously by combining a shield region with a buffer region. CONSTITUTION:A MOSFET structure 30 includes a main body or an n-well region 32; a source region 34 and a drain region 36 are high-concentration doped P-type regions. A shield region 46 is a low-concentration doped n-type region, and its impurity concentration is a little higher than the impurity concentration of the n-well region 32. Buffer regions 42 and 44 are nearly intrinsic or extremely little doped P-type or n-type regions. Furthermore, the shield region 46 isolates a channel region from the main body, substantially reduces the effective concentration of the channel region 38 and reduces a short channel effect much more. In addition, the buffer regions 42 and 44 reduce a concentration gradient between the source 34 and the drain 36 and the main body 32, and, accordingly, reduce a junction capacitance effect.
