Filed: 1991-11-21
Abstract: PURPOSE:To enable the uniform gap control between electrode substrates and to prevent the generation of bubbles when the liquid crystal display panel is rested at a low temp. by disposing hollow spacers having a specific average grain size into the panel. CONSTITUTION:The hollow spacer materials 2 having 1 to 20mum average diameters are dispersely disposed as spacing control particles by a spraying method, etc., on the inside surface of either of the upper electrode substrate or lower electrode substrate of the electrode substrates 1 which consist of transmissive glass substrates and are formed with transparent electrodes on the inside surface side. In addition, a liquid crystal material 3 is provided. The liquid crystal material 3 consisting of an org. polymer has the higher coefft. of thermal expansion to the glass constituting the electrode substrates 1 and, therefore, such a deformation as to diminish the cell gap is generated by the volumetric shrinkage of the liquid crystal material 3 when the panel is rested in a low-temp. atmosphere. The spacers 2 are, however, made deformable at the time of resting at the low temp. by using the hollow spacer materials 2. The drop of the internal pressure is relieved and the generation of the bubbles is prevented.

Title: Evaluation of semiconductor crystal
Inventor: AOKI MASAKI
IPC: H01L21/66
Filed: 1989-11-24
Abstract: PURPOSE:To make it possible to measure an impurity concentration of a deep level by a DLTS method of utilizing a change of a space-charge density in a depletion layer with time by a method wherein a semiconductor single crystal is treated in hydrogen plasma to passivate an impurity of a shallow energy level. CONSTITUTION:An impurity concentration is found from Nt=2(DELTAC/C)Na, the C is a junction capacitance, the DELTAC is the variation of a junction capacitance to correspond to the peak intensity of a DLTS spectrum and the Na is an acceptor concentration, but in case a semiconductor crystal is an N-type crystal, the Na is turned into a donor concentration Nd and either of the concentrations can be measured by a normal C-V method. For example, a P-type Si crystal doped with boron to generate a shallow acceptor level is subjected to hydrogen plasma treatment and the shallow acceptor level is neutralized and is electrically deactivated. When the acceptor level is neutralized in such a way, the spread of a depletion layer is increased and the junction capacitance C is decreased, but as an impurity of a deep level is not affected by hydrogen, the DELTAC is not changed and is the same as its former DELTAC. Accordingly, the DELTAC/C to decide a measurement accuracy is increased. According to this way, an effective measurement using a DLTS method can be executed to the semiconductor crystal containing a high impurity concentration, which is difficult of a measurement using the mormal DLTS method.
