Inventor: TAKEUCHI KAZUHIRO
IPC: G06F17/11
Filed: 1989-07-29
Abstract: PURPOSE:To stably obtain a point of contact without depending upon the combination of geometric shapes by obtaining an extreme value by calculating an intersection point between patterns, and obtaining a multiple root by giving an error allowable value as an input argument, and making the multiple root the point of contact between the patterns. CONSTITUTION:A geometric data access part 1-2 to constitute a data processing part 1 having received a request to calculate the intersection point from a user takes out corresponding geometric data from among the geometric data 4, and an intersection point calculation module 1-1 sets up an equation to calculate the intersection point of these data, and requests an arithmetic part 2 to obtain and inform the extreme value f(alpha). When an expression I in which the error allowable value epsilon given beforehand is substituted as the argument to the informed extreme value f(alpha) is satisfied, the extreme value is decided to be the multiple root, and the multiple root is made to be the point of contact between the patterns. Thus, the multiple root can be decided stably without receiving the influence of the combination of the geometric shape of the pattern, and the point of contact can be surely obtained.

Title: Manufacture of thin film transistor and active matrix liquid crystal display device
Inventor: SETO TOSHISUKE
IPC: H01L21/336
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To improve the yield of production when a TFT is manufactured, to improve the characteristics of the TFT and to improve the quality of a liquid crystal display by a method in which the shrinkage and the cracks of a glass substrate are prevented by irradiating microwaves of specific frequency on the gate insulating film formed on a semiconductor layer. SOLUTION: When a gate insulating film 24, consisting of a silicon oxide film is formed on a glass substrate 20 using a mass-production plasma CVD device, electromagnetic waves, having 3MHz to 30GHz, are projected on the gate insulating film 24 because the gate insulating film 24 contains a large quantity of water when compared with the glass substrate 20. As a result, the water, having a high dielectric constant, is polarized and dielectric heated, and on the other hand, the gate insulating film 24 only is dielectric heated by suppressing the heating which is unnecessary to the glass substrate 20 of low dielectric constant, water is separated from the gate insulating film 24, and the gate insulating film 24 can be modified.  Accordingly, a TFT can be stably operated without shifting its threshold voltage, and an excellent display quality can be obtained on a liquid crystal image device 18.

Title: Optical waveguide
Inventor: WAKAO KIYOHIDE
IPC: G02B6/12
Filed: 1986-08-25
Abstract: PURPOSE:To control a spot size in the horizontal direction, by providing multiple quantum well structures on two sides in the lateral direction of a waveguide layer of a three-dimensional optical waveguide and controlling the refractive index of the waveguide layer by means of electrodes facing each other in the direction vertical to the base body. CONSTITUTION:Multiple quantum well structures 2 are provided on both sides of a homogeneous waveguide layer 4 in the lateral direction and electrodes 7 and 8 are provided on both sides of the layer 4 in the vertical direction. When an electric field is impressed in the direction normal to the well structures, the refractive index of the waveguide layer 4 decreases in accordance with the intensity of the impressed electric field, but the quantity of the variation becomes by far the larger as compared with a homogeneous semiconductor layer whose composition corresponds to the mean value of the refractive index. Therefore, the distribution of refractive index in the horizontal direction over the waveguide layer 4 and multiple quantum well structures 2, which controls a spot side in the horizontal direction, can be controlled effectively by the voltage impressed across the electrodes 7 and 8.
