Title: Manufacture of semiconductor device
Inventor: TSUJI ATSUSHI
IPC: H01L21/768
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To restrain short-circuiting from occurring between wirings by a method, where etching is prevented from proceeding beyond the lower wiring when a contact is formed so as to connect an upper wiring and a lower wiring together, even if the contact is designed in a case where the allowance of the overlap of a contact with the lower wiring is small. SOLUTION: A contact 312 is formed extending from an upper second wiring pattern 311, so as to be connected to a lower first wiring pattern 314 penetrating through a second insulating layer 313. Even if the contact 312 is positioned off the lower first wiring pattern 315, a first insulating film 314 which is slower in etching rate than the second insulating film 313 functions as a stopper to overetching of a contact hole. Therefore, the lower edge of the contact 312 is checked by the first insulating film 314, and advance to the lower wiring pattern 316 is deterred.

Title: Liquid crystal display element and liquid crystal display device
Inventor: UMETSU YASUO
IPC: G02F1/1335
Filed: 1994-04-27
Abstract: PURPOSE:To attain a high contrast ratio by providing a reflecting means by or above the side face of an element to improve the cloudiness for voltage non-impression without damaging the light transmissivity. CONSTITUTION:This device consists of a light scattering element consisting of two transparent substrates 1 having transparent electrode layer formed with picture elements and a dimming layer 3 supported therebetween, and reflection plates 2 provided on both sides of the elements. While a voltage is not impressed to transparent electrodes, light 4 made incident from the display face is scattered by the dimming layer 3 and is emitted as backward scattered light 6 and forward scattered light 7. However, less light is scattered to the inside of the display element face and passes the substrate side faces while being repeatedly reflected in substrates. This light 8 is reflected by reflection plates 2 and passes the dimming layer and substrates again and is emitted as backward scattered light 6 and forward scattered light 7. As the result, the intensity of scattering is increased, and light 4 made incident from the display face is straightly transmitted without losing the transparency by the dimming layer 3, thus improving the contrast.
