Title: Production of amorphous ni-co-b alloy film
Inventor: SAITO TETSUO
IPC: C23C18/50
Filed: 1991-09-03
Abstract: PURPOSE:To allow an amorphous Ni-Co-B alloy film to show excellent characteristics as a soft magnetic thin film and a high resistance thin film by adding metal salt and a reducing agent to a plating bath to regulate it and incorporating boron, in a high concentration, into the immersed material to be plated while the decomposing-unstable state of the plating bath is evaded. CONSTITUTION:An amorphous alloy film is produced by an electroless plating method. As metal salt, nickel chloride and cobalt chloride in an optional ratio are added, and, as a reducing agent, a soln. of sodium borohydride is added to regulate the plating bath. The immersed material to be plated is incorporated with boron in a high conc., while the decomposing-unstable state of the plating bath is evaded by adding the soln. of sodium borohydride to the plating bath little by little under the conditions in which the electroless plating is most suitably executed, there by the amorphous Ni-Co-B alloy film is produced. As a stabilizer, lead salt is added to the plating bath. In this way, the alloy film excellent in solderability and, furthermore, small in the discoloration of the surface caused by heat can be produced.

Abstract: PURPOSE:To measure an accurate output pulse width by setting a plurality of strobes whose spacing has been fixed to a prescribed output pulse width, and by moving them with a prescribed step for finding out the output pulse width of an IC. CONSTITUTION:A strobe 4 for a split 1 is set in the position slightly before the time of change of an expected output phiOUT to an input phiIN. The strobe 5 for a split 2 is set so as to keep a specified width 6 for the 'High' interval of the output pulse phiOUT from the strobe 4. In this condition, when the test pattern is executed for the purpose of a test, the output phiOUT is 'LOW' to the expected value 'High' of the strobe 4, and the judgment becomes 'Fail'. Next, the 'Fail' is released, and arbitrary step values are added to the strobes 4, 5 respectively, and then the test pattern is again executed. When the strobes for the splits 1, 2 are set in the positions 4a, 5a respectively, the outputs phiOUT become 'High' output to both the strobes 4a, 5a, and the judgment of the test pattern becomes 'Pass', and it can be confirmed that the outputs phiOUT satisfy the specified value 6 of the 'High' section.

Title: Conductivity modulated vertical type mosfet
Inventor: KUMAGAI NAOKI
IPC: H01L29/739
Filed: 1986-10-22
Abstract: PURPOSE:To prevent a latch up from occuring even if current is concentrated in a cell by a method wherein the length of a source region in the width direction to a cell located on a specific position such as a cell at the peripheral part adjoining a gate pad part, etc., is made shorter than the length of a source region located on any other ordinary positions. CONSTITUTION:The length of N<+> source region 6a formed in a channel region of a cell 23 at the peripheral end part adjoining a gate pad part 21 is shortened. Then, the emitter short-circuiting effect at a parasitic thyristor can be enhanced to prevent a latch up from occuring even if current is concentrated in the cell 23. However, when said structure is applied to any cells other than the cell 23, the contact area between a cathode electrode 9 and an N<+> source region 6 is reduced to cause a defective contact or an increase in contact resistance raising ON voltage of an element by decrease in electron injection dose. On the contrary, in such a constitution, the N<+> source region is slightly changed only in the cell 23 at the peripheral end part adjoining the gate pad part 21 so that the latch up phenomenon due to current concentration may be prevented from occuring without raising the ON voltage of element.
