Title: Manufacture of quaternary mixed crystal of immiscible compound semiconductor
Inventor: ONABE KENTAROU
IPC: H01L21/22
Filed: 1987-01-21
Abstract: PURPOSE:To obtain a quaternary mixed crystal of compound semiconductor having a uniform composition even in an immiscible quaternary mixed crystal, by alternately laminating super-thin film of binary compounds, whose lattice constants are approximately equal, forming a super lattice, and thereafter disorganizing the super lattice by impurity diffusion. CONSTITUTION:The super thin films of two kinds of binary compounds AC and BD (A-D are different elements) do not have common components but have the approximately equal lattice constants. Said super-thin films are alternately laminated, and a super lattice is formed. Impurities are diffused in a suitable concentration, and the super lattice is disorganized. Thus a quaternary mixed crystal, whose compositions are uniform, is obtained. The compositions are A1-x, Bx, C1-x and Dx. The atomic arrangement on the crystal lattice is disorganized without changing the average lattice constant. Therefore, the quaternary mixed crystal having the uniform compositions can be obtained even in compounds, in which a thermally equivalent, uniform mixed state is not present.

Title: Mis type semiconductor integrated circuit device
Inventor: KOMATSU MICHIO
IPC: H01L29/78
Filed: 1986-01-24
Abstract: PURPOSE:To improve the radiation resistant characteristic of an MIS type semiconductor integrated circuit device by depositing a boron-phosphorus-glass (BPSG) on a region except an element separating region made of a thick oxide film, i.e., a thin insulating film equivalent to a gate insulating film to suppress the deterioration of the characteristics of a parasitic MIS transistor after exposing. CONSTITUTION:The different points of radiation resistant MIS type semiconductor integrated circuit device from conventional one resides in that BPSG having 0.1-10mum of thickness is used as an interlayer film 16. The BPSG contains 7-15mol% of boron and 8-4mol% of phosphorus. When the BSPG is thus used, the variation in the threshold value of a parasitic MIS transistor formed on a region X after exposed with radiation is reduced by approx. 1 as compared with a CVD silicon oxide film. Thus, a leakage current is remarkably reduced, and the dielectric strength of the transistor can be raised in the amount that the impurity density of the conductive region is not so raised.
