Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To shorten manufacturing process of a semiconductor device having a silicide layer and a non-silicide layer. SOLUTION: After ion implantation for forming a source and drain diffusion layer is performed, continuously, thermal oxidation treatment is rapidly performed in a short time, and a new thermal oxide film is formed on an interface of a silicon substrate 1 and a protective oxide film 3. Photoresist 7 for forming a non-silicide layer is formed on a thermal oxide film 6 constituted of the newly formed thermal oxide film containing the protective oxide film 3. After the thermal oxide film 6 is etched, the photoresist 7 is eliminated, thereby forming an oxide film 8 for siliciding block which is constituted of the thermal oxide film 6 in a part corresponding to the photoresist 7. A Ti film is formed on the whole surface containing the oxide film 8 for siliciding block. After annealing treatment for siliciding is performed, the Ti film 9 which is not yet reacted is eliminated.  As a result, a diffusion layer 4 as a non-silicide layer having high non-silicide property, and a diffusion layer 5 having a silicide layer 10 on the surface are formed.

IPC: C03B23/00
Filed: 1990-11-19
Abstract: PURPOSE:To obtain a glass preform capable of providing an optical element excellent in shape accuracy and transmittance without causing chipping or breakage in corner parts by preheating a material for the optical element, thereby deforming the corner parts thereof and simultaneously changing also the side into a mirror surface. CONSTITUTION:A glass material for an optical element is preheated to thermally deform and round corner parts thereof. Its side is further simultaneously changed into a mirror surface to afford a preform for the optical element. In a step for introducing the resultant preform into a space between a top force and a bottom force and forming the optical element, the forming pressure is reduced once or more or regulated to zero in the course of its forming step. No chipping or breakage is caused in the corner parts due to surface contact with a metallic mold in introducing the glass preform into the metallic mold according to the aforementioned method. Furthermore, since the side of the glass preform is the mirror surface, transmittance of the resultant optical element is also improved.

Abstract: PURPOSE:To display a high-picture-quality image by making the orientation action axes of GH-FLC of a polarizer and an analyzer orthogonal, and the orientation action axis of a modulation FLC parallel to either of the orientation action axes.

When temperature is changed, since FLC layers 1, 2, and 3 are composed of materials having same temperature change of a cone angle and the direction of the molecular axis 15 of the first layer is changed, the direction of outgoing light E1 is also changed, a molecule axis 25 of the second layer 2 also makes the same change, the molecule axis 35 of the third layer 3 also makes the same change with the directions of an incident light E1 and the molecule axis 25 in accord, and a condition orthogonal to the molecule axis 15 of the first layer 1 is retained. Good quality picture image display in a wide temperature range is possible because of no relative change of the polarizer 1, a modulation piece 2, and the analyzer 3 even temperature is changed.
