Title: Formation of guard ring
Inventor: KURODA FUMIHIKO
IPC: H01L21/329
Filed: 1986-09-16
Abstract: PURPOSE:To sufficiently diffuse an impurity which was doped by ion implanta tion in the horizontal direction during an annealing process by a method wherein a slight lattice-defect which can be removed at a later thermal process is intro duced near the surface of a semiconductor crystal substrate. CONSTITUTION:For example, a hydrogen ion as the second chemical element 1 is irradiated onto the whole surface of an InP layer. During this process, a lattice defect is introduced into the whole surface of a substrate at a depth of about 1 mum, and a latticedefect introduced layer 2 is formed. Then, Be as the first impurity chemical element 3 is doped by ion implantation by making use of an insulating film such as SiO2 or the like as a selective mask. This assembly is then annealed in an atmosphere of PH3 at a temperature of 750 deg.C. Because the implanted Be is diffused quickly inside the lattice-defect introduced layer, the Be is diffused extensively in the vertical direction as well as in the horizontal direction. At the same time, the introduced lattice defect is also removed. It is, therefore, possible to form a guard ring whose withstanding voltage is sufficiently high.

Abstract: PROBLEM TO BE SOLVED: To remarkably improve the operability in execution without causing a deterioration of the fluidity of a monolithic refractory containing a slaking resistant magnesia fine powder by directly sticking silica particles to the surface of a fine powder and regulating the average particle diameter thereof to a prescribed size. SOLUTION: This slaking resistant magnesia fine powder is obtained by directly sticking silica particles to the surface of a fine powder and regulating the average particle diameter thereof to 20μm size. The method for producing the slaking resistant magnesia fine powder is to mix the silica particles (e.g. fused silica) with a magnesia fine powder having <=20μm average particle diameter (e.g. seawater magnesia) in a mixer having a strong grinding force and/or impulsive force. Otherwise, the fine powder is obtained by pulverizing the magnesia fine powder to a size of <=20μm average particle diameter in the presence of a silica fine powder.  The monolithic refractory excellent in slaking resistance and fluidity is obtained by blending 4-30% slaking resistant magnesia fine powder in the fine powder, in the monolithic refractory comprising the aggregate, the fine powder, a dispersing agent and a hardening material blended therein.

Abstract: PURPOSE:To suppress the deformation and erosion of a solenoid through the lapse of time by allowing an equal pressure to act through a communication passage on both the sides of the valve body of a solenoid valve and partitioning an armature chamber and a balance chamber for a spill chamber for accommodating a valve head part, by a sliding part. CONSTITUTION:If the solenoid 35 of a solenoid valve 20 electrically conducts during the compression cycle of a fuel injection pump, an armature 31 is attracted to a stator 38, and a valve head 23 is set on a valve seat 24. Then, the communication between the low pressure side and high pressure side through an annular recessed part 47 is cut off, and fuel is jetted from the fuel injection pump. At this time, the pressure in an armature chamber 35 increases through the leak of the high pressure excessive fuel. In order to dispose of the pressure increase, the clearance (pressure increase preventing passage) in the slidable part 46b between the second valve body member 22b and a header 25 is set larger than that in the part before and behind the valve head part 23, i.e., the slidable part 46a between the first valve body member 22a and a valve housing 21. Accordingly, the pressure is released to a spill chamber 27 through a balance chamber 55 from a communication passage 56.
