Title: Manufacturing of cubic system boron nitride
Inventor: SUZUKI MASAHARU
IPC: C04B35/583
Filed: 1989-08-04
Abstract: PURPOSE:To obtain a highly pure cubic system boron nitride or its sintered product by incorporating a diamond-shaped boron nitride into a low-pressure phase boron nitride at the time of producing the cubic system boron nitride by subjecting the low pressure phase boron nitride to a static, noncatalytic treatment at an ultra-high pressure and temp. CONSTITUTION:The low pressure phase boron nitride (hBN and/or tBN) contg. a diamond-shaped boron nitride (rBN) is processed into a disk plate or powder. It is then filled in a belt type high temp. producing device and, after that, first pressure and then temp. is raised to attain the desired high temp. and pressure. At such high temp. and pressure, a treatment is performed for a predetermined time. After treatment, at first, the temp. and then the pressure is reduced back to room temp. and 1atm, respectively, and the cubic system boron nitride (cBN) produced by the high temp. and pressure treatment is removed from the device. When the low pressure phase boron nitride contg. rBN is treated at a high temp. and pressure, rBN is first converted into cBN in a short time by nondiffusing transition and hBN or tBN is then incorporated into the cBN particles as they grow and thereby converted into cBN. Thus, highly pure cBN particles are obtained.

Abstract: PURPOSE:To reduce the disconnection of a picture element electrode at the stage of an end part of gate wiring by forming the holding capacitor which includes the gate wiring and an impurity silicon layer as both electrodes and connecting the picture element electrode to the impurity silicon layer. CONSTITUTION:The gate wiring 2 is formed on an insulating substrate 1, a 1st insulating layer 3 is formed on the insulating substrate 1, and further the impurity silicon layer 4 is formed so as to cross the gate wiring 2. When an intrinsic silicon layer 5 is patterned, the impurity silicon layer 4 at the part where a 2nd patterned insulating layer 6 is not formed is also etched at the same time and made thin. The picture element electrode 7 is formed on the impurity silicon layer 4 so as to be brought into contact with the impurity silicon layer 4. Consequently, the impurity silicon layer 4 at the end part step part of the gate wiring 2 of thin film thickness is not etched at all, so there is no possibility of the disconnection of the impurity silicon layer 4 at the end part step part due to the etching.
