Abstract: PURPOSE:To reduce the rate of production of an soft error by expanding a bottom region of a groove formed in a semiconductor substrate to opposite sides of the bottom of the groove beyond the width of the bottom of the groove substantially in parallel to the surface of the semiconductor substrate. CONSTITUTION:After a thin silicon oxide film 11 is formed on the side wall and the bottom of a groove 10 formed in a silicon substrate 1 by thermal oxidation, a silicon nitride film 12 and a silicon oxide film 14 are formed on the silicon oxide film 11 in succession. Then, the silicon oxide film 11, and the silicon substrate 1 are etched vertically by anisotropic etching. The side wall of the groove 10 is left behind such that the silicon nitride film 12 is coated with the silicon oxide film 14, and the bottom surface of the groove 10 such that the silicon substrate 1 is exposed. Additionally, the bottom region of the groove 10 is subjected to isotropic etching and expanded such that the width of the bottom of the groove is greater than the groove width. After the silicon oxide films 13, 14 are removed, a thick silicon oxide film 15 is formed on the bottom region of the groove 10 by thermal oxidation. Hereby, a funneling phenomenon due to incident alpha rays can be prevented from being developed.

Title: Data processing method for information recording and reproducing device
Inventor: HORIUCHI TADASHI
IPC: G06F12/08
Filed: 1994-10-28
Abstract: PURPOSE: To smoothly execute data transfer by interrupting write processing and preferentially executing the processing of a read processing instruction when read data obtained by a read processing instruction do not coincide and overlap with unprocessed data written in a cache memory by a preceding write processing instruction. CONSTITUTION: At the time of receiving a read request, a CPU 8 compares LBA and length stored in a storage part 7 by a preceding write processing instruction with LBA and length newly stored in the storage part 7 by a current read processing instruction. When the LBA and length corresponding to the read request coincide and overlap with the LBA and length corresponding to the preceding write request, read processing is waited until the writing of write data stored in a cache memory 6 in a medium ends. When both the data do not coincide with each other, the CPU 8 temporarily interrupts write command processing for data stored in the memory 6 and prefrentially executes a read command.

IPC: H01J9/14
Filed: 1984-12-18
Abstract: PURPOSE:To reduce the generation of deformation at the color screening electrode due to electronic beam shocks by forming in part of the surface of a heat radiating layer such a substance that hampers conversion of kinetic energy of electron beam to thermal energy. CONSTITUTION:A heat radiating layer 2 is formed on both sides of, and on the ramp 8 of the hole 6 of, a color screening electrode 13, while a diffusing layer is formed on the surface of the beam-shocked side of, and on the ramp 8 of the hole 6 of, the color screening electrode 13. By depositing a thin aluminum film over the double layer composed of the heat radiating layer 2 and the diffusing layer 4 after it is heated at a low temperature, it is possible to have it acquire conductivity. Since the diffusing layer 4 comprises heavy metals, it is generally of low electric conductivity. By depositing some substance with high electric conductivity like aluminum, therefore, it becomes possible to scatter and discharge electrons accumulated on the surface of the color screening electrode.
