摘要: To manufacture in high productivity a semiconductor device capable of securely achieving element isolation by a trench-type element isolation and capable of effectively preventing potentials of adjacent elements from affecting other nodes, a method of manufacturing the semiconductor device includes: a step of forming a first layer on a substrate; a step of forming a trench by etching the first layer and the substrate; a step of thermally oxidizing an inner wall of the trench; a step of depositing a first conductive film having a film thickness equal to or larger than one half of the trench width of the trench on the substrate including the trench; a step of removing a first conductive film from the first layer by a CMP method and keeping the first conductive film left in only the trench; a step of anisotropically etching the first conductive film within the trench to adjust the height of the conductive film to become lower than the height of the surface of the substrate; a step of depositing an insulating film on the first conductive film by the CVD method to embed the upper part of the first conductive film within the trench; a step of flattening the insulating film by the CMP method; and a step of removing the first layer.

摘要: In the process of manufacturing a semiconductor device, a first layer is formed on a substrate, and the first layer and the substrate are etched to form a trench. The inner wall of the trench is thermally oxidized. On the substrate, including inside the trench, is deposited a first conductive film having a thickness equal to or larger than one half of the width of the trench. The first conductive film on the first layer is removed by chemical mechanical polishing such that the first conductive film remains in only the trench. The height of the first conductive film in the trench is adjusted to be lower than a surface of the substrate by anisotropically etching the first conductive film. An insulating film is deposited on the substrate by chemical vapor deposition to cover an upper surface of the first conductive film in the trench. The insulating film is flattened by chemical mechanical polishing, and the first layer is removed.

摘要: A technique for preventing a decrease in alignment accuracy during a photolithography process is provided. A substrate (1) is prepared, in the surface (80) of which trenches (7) for use as alignment marks and trenches (17, 27) each forming an element isolation structure are formed and on the surface (80) of which a polysilicon film (3) is formed, avoiding the trenches (7, 17, 27). The trenches (7, 17, 27) are filled with an insulation film (30). The insulation film (30) is then selectively etched to partially remove the insulation film (30) in the trenches (7) and to leave the insulation film (30) on side and bottom surfaces (81, 82) of the trenches (7). Using the insulation film (30) in the trenches (7) as a protective film, the polysilicon film (3) is selectively etched. The use of the insulation film (30) in the trenches (7) as a protective film prevents the substrate (1) from being etched and thereby prevents the shape of the trenches (7) from being changed. This results in prevention of a decrease in alignment accuracy during a photolithography process.

摘要: A semiconductor device—which includes surface-type n-channel and p-channel single gate transistors by formation of fixed charges within a gate oxide film—and a manufacturing method therefor. A voltage is applied between an electrode connected to a gate electrode and an electrode connected to an N+ region formed in an n-well, and electrons are implanted into the gate electrode at high energy from a substrate, thereby producing fixed negative electric charges in a gate oxide film within an range of 1E11 cm−2 to 1E14 cm−2. An appropriate value for Vth is obtained in the surface channel MOSFET. Therefore, there are solved problems associated with a dual gate structure; namely, a complicated process flow, etch residues or excessive etching due to a difference in etch rate between n-type polycrystalline silicon and p-type polycrystalline silicon, and the deterioration of a gate oxide film due to penetration of boron ions.
