Title: Semiconductor device
Inventor: AKIBA TOSHIHIKO
IPC: H01L21/822
Filed: 1989-08-14
Abstract: PURPOSE:To reduce the area of a semiconductor element having a conductive region layer for applying substrate bias voltage by forming a region layer of one conductivity for applying the substrate bias voltage in a region layer of opposite conductivity formed on a semiconductor substrate of one conductivity. CONSTITUTION:Source region layer of MOSFET, for example, is provided as a region layer 6 of opposite conductivity and a region layer 8 of one conductivity for applying substrate bias voltage is provided therein, where the polarity thereof is set to be same as that of a semiconductor substrate 2. A single contact hole 11 is formed in a layer insulation film 9 over a region including the entire region layer 9 of one conductivity and a part of the region layer 6 of opposite conductivity within such range as the positional shift with respect to the region layer 6 of opposite conductivity is absorbed. Consequently, the region layer 8 of one conductivity is contained in the contact hole 11 even if the contact hole 11 is associated with positional shift within allowable range. By such arrangement, the area of the region layer 6 of opposite conductivity is narrowed and the size of the element is reduced enabling high integration of semiconductor device.

Title: Production of sintered iron ore
Inventor: KODAMA TAKUMA
IPC: C22B1/20
Filed: 1987-08-26
Abstract: PURPOSE: To produce sintered ore which is partially different in basicity and is improved in the low-temp. reduction collapsing property in a blast furnace with simple equipment by laminating and supplying sintering raw materials having different basicities into an ore feed hopper, then supplying the materials onto a pallet and sintering the same at the time of producing the sintered ore for blast furnace.  
     CONSTITUTION: The low-temp. reduction collapsing property of the sintered ore for the blast furnace is poorest in a 1.2W1.8 range of the basicity (CaO/SiO 2 ) thereof and, therefore, the raw material 2a which is so compounded as to have the basicity off the above-mentioned 1.2W1.8 range, for example, to have 1.87 and the raw material 2b compounded to have, for example, 0.7 are supplied in the form of layers by belt conveyors 5a, 5 into the ore feed hopper 6 in the case of producing the sintered ore having 1.0W2.5 average basicity. These materials are supplied by a drum feeder 7 onto the pallet 12 where the raw material of 1.87 basicity and the raw material of 0.7 are so laminated as to have 1.0W2.5 average basicity, then the materials are sintered. The sintered ore having the improved low-temp. reduction collapsing property and 1.0W2.5 average basicity is produced with the conventional simple apparatus for producing the sintered ore by sintering the heterogeneously mixed raw materials having the high basicity and low basicity in the basicity distribution.
