Description of the invention ( 5) In order to protect the connection part from external electricity, 撃 '. To ensure the stability of the connection / attachment of the terminal, the terminal electric Huan 2 1 table is provided. In the aluminum wire cage, the resin J 2 is thicker because of the J rise, 2 5 at the terminal connection portion. In F. C 0 G. Of f 4 A and 4 B, the wafer 4 2 is oriented to The terminal part 43 formed below is mounted on the glass substrate 40 for manufacturing the circuit, and the terminal electrode 41 of the circuit is connected by the flange 4 4 (Fig. 4A) or the metal particles (Fig. 4B). The terminal portion 43 is formed. The resin 4 5 seals this portion to fix the wafer 4 2 to the substrate 40. Therefore, since the terminal connection portion has a thickness approximately corresponding to the thickness of the wafer, materials other than the thin display can be manufactured. For example, a transparent conductive oxide film (IT 0 (Indium Tin Oxide), etc.) can be used for a terminal on a glass substrate. When an active matrix circuit of a liquid crystal display is formed on a sloped glass substrate, since a transparent conductive oxide film is used in many cases It constitutes most of the upper-layer wiring, so FC 0 G is better in this respect.

In this doping, after using phosphine (p Η 3) as the doping gas-like phosphorus to introduce the entire surface, only the TF Τ active layer 5 0 3 is covered with photoresist, and diborane (B2Η 6) is used as the dopant. The doping gas introduces boron into the TF T active layers 504 and 505. The dose is 4 X 1 0 14 to 4 X 1 0 15 atoms / cm in the dish, and 1 X, 10 15 to 1 · 8 X 1 0 15 atoms / cm 3 in boron. The dose of boron is higher than that of phosphorus. Accordingly, N-type regions 5 1 3 and P-type regions 5 1 4 and 5115 are formed. (Fig. 5D) KrF excimer light (248 nm wavelength and 20 n s pulse width) is irradiated to improve the crystallinity of the portion where the crystallinity is deteriorated due to the introduction of impurities into the impurity region. The laser energy density is 2'0 0 to 40 OmJ / cm2, preferably 2 50 to 30 OmJ / cm2. Therefore, the N-type and P-type regions are activated. The sheet resistance in these areas is 200 to 8 0 Ω / square. This treatment can be performed by thermal annealing in the thermal resistance range of the gate.

Description of the invention (n) 3 8 0 to 5 0 ° C, for example 4 3 0 ° C, the silicon oxide film 6 2 2 formed has a relatively low etching rate and is solid. This is because—nitrogen oxide is used as a raw material gas, so a silicon oxide / nitride nitride film containing 1 to 10% nitrogen is obtained. Ester-added buffered hydrofluoric acid (ABHF) (hydrofluoric acid: ammonium fluoride: acetic acid = 1- .:: 50: 50) is used at 23 ° C, and the standard etching rate is 80 to 100. 0A / minute. Plasma CVD forms a 500 A thick amorphous silicon film. A silicon oxide film was formed on the surface of the amorphous silicon film by thermal annealing at 55 ° C for 1 hour in an oxygen-containing atmosphere (estimated about 40 to 100 A). By spin coating, a 1 to 100 ppm nickel ester acid solution is used to form an extremely thin film of nickel acetate. First, a thin silicon oxide film is formed on the surface of the amorphous silicon film, and the solution is distributed on the surface of the amorphous silicon film. ’Thermal annealing at 5 50 ° C for 4 hours in a nitrogen-containing atmosphere. Nickel ester is decomposed at about 400 ° C to obtain nickel. Since the nickel acetate film is roughly attached to the amorphous silicon film, nickel diffuses to the amorphous silicon film by thermal annealing. Therefore, the amorphous silicon film is crystallized to form a crystalline silicon region.

(Figure 7C) The TTF structure of the peripheral logic circuit may be different from the active matrix circuit. For example, in the offset structure of FIG. 7D where the TFT gate and the drain of the active matrix circuit are separated from each other, the OFF current can be further reduced. In order to perform the same high-speed operation as the peripheral logic circuits, the semiconductor has to be crystallized, the source and the drain are also crystallized, and the sheet resistance is low. Although the laser is irradiated to manufacture peripheral logic circuits, the above requirements are satisfied because the channel-shaped area and the portions corresponding to the source and the drain are crystallized. In order to further promote the crystallization of the source and drain electrodes, catalytic elements that promote amorphous crystals (such as nickel, platinum, palladium, cobalt, or iron) can be used at a concentration of 1 X 1 0 17 to 2 X 1 0 μ atoms / cm 3 Add silicon film.

The first-gate wiring electrodes 802 to 805 are formed on a green surface of a glass substrate on which a 10 G thick silicon nitride film (not shown) is formed. A polycrystalline silicon film with a thickness of 300 A, which is doped with phosphorus to reduce resistance, is etched to form gate wiring electrodes 802 to 805. Low-pressure CVD forms a polycrystalline silicon film. There is a polycrystalline state when this film is formed. To obtain a polycrystalline silicon film, there are the following methods except the above method. That is, after forming an essentially amorphous silicon film by plasma CVD or low-pressure CVD, impurities such as phosphorus are introduced into the silicon film by ion doping. Furthermore, thermal annealing is performed at 500 to 600 ° C. In thermal annealing, elements that promote crystallization, such as nickel, can be slightly incorporated. In the embodiment, silicon is used, but various metal silicides can be used. Plasma CVD forms a silicon nitride film 806 with a thickness of 300 to 600 A (for example, 400 A), which is also used as a gate insulating film. Plasma CVD forms an amorphous sand film having a thickness of 3.0 to 100 A (for example, 500 A), and is then etched to form island silicon regions 807 to 809. (Figures 8 A and 9 A) Plasma CVD forms a silicon nitride film 8 1 0 to 3 0 to 6 0 0 A (for example, 2 0 0 A), which is also used as a gate insulating film. The laser light strikes only the peripheral circuit portion, and crystallizes the island-shaped silicon films 808 and 809. Laser is XeCl excimer laser (308nm wavelength). The laser irradiation energy density and the number of pulses vary depending on the characteristics of the silicon films 808 and 809 and the silicon nitride film 810.

Description of the invention (19 ) Contact hole for the wire (not shown). This contact hole is used to form a contact between the first gate connection and the second gate connection (formed on the first gate connection, corresponding to the contact 8 4 5 as shown in FIGS. 10A and 10B). After the contact hole is formed, an aluminum film 8 1 1 with a thickness of 3000 to 800 OA (for example, 30000 A) is formed by sputtering. When the aluminum film 8 1 1 contains 0.1 to 0.5% by weight of rhenium (Sc), generation of hillocks can be prevented (see FIGS. 8 B and 9 B). The aluminum film 8 1 1 is etched to form a second gate wiring electrode 8 1 2 to 8 1 5. Therefore, a contact between the first gate wiring and the second gate wiring is formed through the formed contact hole. The contact hole must be completely covered with the second gate wiring. This is because when the first gate wiring made of silicon is exposed at the contact hole, current flows through the exposed portion during the anodizing process without anodizing. (Figure 8. and 9C) In the electrolyte, a current is sent to the second gate terminal electrodes 8 1 to 8 1 5. An ethylene glycol solution obtained by adding ammonia to 3 to 10% tartaric acid and having a pH of 6.8 to 7.2 was used. When the solution is about 10 ° C below the room temperature, an oxide film with high quality is formed. Therefore, barrier anodic oxides 8 16 to 8 1 9 are formed on the upper and side surfaces of the second gate wiring electrode. The thickness of the anodic oxide is proportional to the applied voltage, and preferably 100 to 3 0 0A. A 20000A thick anodic oxide was formed at 150V. To obtain an anodic oxide with a thickness of more than 3 00 A, more than 2 500 V must be applied. But this affects the T F T characteristics.

(Figs. 8F and 9F) A metal such as a titanium film 830 having a thickness of 50 to 500 A is formed on the entire surface by sputtering. (Figures 8G and 9G) At 450 to 500 eC (for example, 500 ° C) for 10 to 60 minutes, titanium reacts with silicon to form silicide (titanium silicide) regions 8 3 1 to 8 3 6. In this thermal annealing, doped impurities are further activated. Laser annealing with laser light irradiation, lamp annealing with visible light irradiation or near-infrared light irradiation, and thermal annealing with silicide treatment can be performed. The titanium film 830 was etched using an etching solution obtained by mixing hydrogen peroxide, ammonia, and water at a ratio of 5: 2: 2, respectively. Since the titanium film (for example, the titanium film formed on the silicon nitride film 806 and the anodic oxide film) that does not contact the active layer is left in a metallic state, it can be etched in this etching process. On the other hand, titanium silicide Does not etch, so it is still. (Figures 8A and 9H) (Please read the precautions on the back before filling this page)
