摘要:
In a cleaning method and a cleaning apparatus of a silicon substrate, after wet cleaning or etching of the substrate having a silicon surface is carried out, and during or after a pure water rinse of the substrate, an oxide film with a thickness of 10 to 30 Å is formed on the silicon surface by rinsing the substrate by pure water added with an oxidizer, and then the substrate is dried. Since drying is carried out after the oxide film is formed on the silicon surface, the occurrence of a water mark can be prevented.

Method of fabricating a semiconductor device. A glass substrate such as Corning 7059 is used as a substrate. A bottom film is formed. Then, the substrate is annealed above the strain point of the glass substrate. The substrate is then slowly cooled below the strain point. Thereafter, a silicon film is formed, and a TFT is formed. The aforementioned anneal and slow cooling reduce shrinkage of the substrate created in later thermal treatment steps. This makes it easy to perform mask alignments. Furthermore, defects due to misalignment of masks are reduced, and the production yield is enhanced. In another method, a glass substrate made of Corning 7059 is also used as a substrate. The substrate is annealed above the strain point. Then, the substrate is rapidly cooled below the strain point. Thereafter, a bottom film is formed, and a TFT is fabricated. The aforementioned anneal and slow cooling reduce shrinkage of the substrate created in later thermal treatment steps. Thus, less cracks are created in the active layer of the TFT and in the bottom film. This improves the production yield. During heating of the substrate, it is held substantially horizontal to reduce warpage, distortions, and waviness of the substrate.

A polysilicon pattern constituting an active portion of a TFT is formed on a substrate so as to be curved to generally assume a U shape, and a gate pattern is formed as a straight conductor pattern. The gate pattern is so disposed as to cross the U-shaped polysilicon pattern plural times. The silicon pattern comprise a plurality of channel regions and impurity regions of which alignment is symmetrical.

There is provided a high quality liquid crystal panel having a thickness with high accuracy, which is designed, without using a particulate spacer, within a free range in accordance with characteristics of a used liquid crystal and a driving method, and is also provided a method of fabricating the same. The shape of a spacer for keeping a substrate interval constant is made such that it is a columnar shape, a radius R of curvature is 2 μm or less, a height H is 0.5 μm to 10 μm, a diameter is 20 μm or less, and an angle α is 65° to 115°. By doing so, it is possible to prevent the lowering of an opening rate and the lowering of light leakage due to orientation disturbance.

It is an object of the invention to provide a lightweight semiconductor device having a highly reliable sealing structure which can prevent ingress of impurities such as moisture that deteriorate element characteristics, and a method of manufacturing thereof. A protective film having superior gas barrier properties (which is a protective film that is likely to damage an element if the protective film is formed on the element directly) is previously formed on a heat-resistant substrate other than a substrate with the element formed thereon. The protective film is peeled off from the heat-resistant substrate, and transferred over the substrate with the element formed thereon so as to seal the element.
