Title: Semiconductor device of multilayer wiring structure and its manufacture
Inventor: MIZUMURA AKIRA
IPC: H01L23/522
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To form a spacer layer for insulation in microminiature contact holes with reliability and space saved in order to provide insulation from intermediate conductive layers in the contact holes between an upper conductive layer and a lower conductive layer. SOLUTION: A required multilayer wiring layer is formed, and a contact hole 40 which runs from an insulating layer 36 above the multilayer wiring layer to a lower conductive layer 30 is formed. The end face of an intermediate conductive layer 34 within the hole is retreated to increase the diameter of part of the contact hole 40. Thereafter, a thick insulating film is formed on the entire surface, and is etched back. An upper conductive layer 54 is formed and is connected with the lower conductive layer 30. This forms a spacer layer for insulation in the widened part 42 of the contact hole 40.  If etch selectivity with the upper insulating layer 36 cannot be obtained during etching back, a process is added in the course of etching in which a stopper layer 38 is formed on the upper insulating layer 36 and a side wall protective layer 46 that is highly resistant to etching and protects at least the lower corners of the upper insulating layer 36 is formed. This obtained a thin, uniform side wall 44 of two-layer structure, which acts as a spacer for insulation together with the diameter-increased part 42.

Filed: 1981-01-30
Abstract: PURPOSE: To uniformly soldify the whole of soil layer of soft ground by a method in which a grout of bad permeability, whose gelling time is within a specific period of time is first injected into the ground, and then another grout of a good permeability is injected into the ground.  
     CONSTITUTION: Plural grouts having different permeabilities are injected into the ground through a multiple injection tube. In this case, plural grout injection ports are placed at places of different depths in the direction of injection, a quick setting grout whose gelling time is within 30sec is first injected into the ground to form a seal having a packing effect in space or weak portion around the injection tube. Then, another grout of a better permeability is injected in an overlapping menner into the quick setting grout-injected region through an injection pipe positioned at a depth different from the previous injection port. The grout of better permeability can penetrate into the places other than the quick setting grout-injected ground without escaping to the ground's surface; that is, the grout penetrates into places where the grout of bad permeability could not penetrate. Such a process is repeated and  the whole of the ground can be completely stabilized.
