Title: Manufature of semiconductor device
Inventor: IIZUKA NORIO
IPC: H01L21/425
Filed: 1986-09-02
Abstract: PURPOSE:To form a P-type layer and to obtain an efficient blue light emitting diode by implanting zinc ions around the step of implanting nitrogen, phosphorus, arsenic or antimony ions to II-VI compound semiconductor layer, and heat treating it after the ion implanting steps. CONSTITUTION:When a large quantity of P ions are implanted to obtain a high concentration P-type layer to ZeSe of II-VI compound semiconductor, the stoichiometric composition of a crystal cannot be maintained. As a result, the concentration of P which occupies the positions between lattices is increased, and its activation rate is reduced. Thus, it becomes difficult to obtain the high concentration P-type layer. However, the stoichiometric composition can be held by implanting Zn ions together with the P ions so that the P can be feasibly substituted for Se site. Resultantly, a low resistance and high concentration P-type layer can be performed. The heat treatment after ion implanting is executed by covering the surface with an SiO film by vacuum depositing and heating to 500 deg.C by a halogen lamp to prevent the Se from being evaporated. A high sheet carrier concentration of 8X10<12>cm<-2> can be obtained for the ion implanted layer of 2X10<13>cm<-2>.

Title: Liquid crystal display
Inventor: BUARUTAA KEENIHI
IPC: G02F1/1335
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in a liquid crystal display. SOLUTION: A polymer dispersion liquid crystal(PDLC) does not require the utilization of a polarizing filter and a half-reflection mirror required in the several kinds of other liquid crystal displays(LCDs). By eliminating the need for such a polarizing filter and mirror, the attenuation of light generated by the filter and the mirror is eliminated. Thus, less input quantity of the light is sufficient and thus, a battery service life is increased in a device with power supplied by a battery. Also, by providing plural color filters in respective picture elements and illuminating the liquid crystal(PDLC) at a display edge part, color display is realized.
