A transistor formed on a monocrystalline Si wafer is temporarily transferred onto a first temporary supporting substrate. The first temporarily supporting substrate is heat-treated at high heat so as to repair crystal defects generated in a transistor channel of the monocrystalline Si wafer when transferring the transistor. The transistor is then made into a chip and transferred onto a TFT substrate. In order to transfer the transistor which has been once separated from the monocrystalline Si wafer, a different method from a stripping method utilizing ion doping is employed.

PCT No. PCT / JP97 / 00572 Sec. 371 Date Jan. 8, 1998 Sec. 102(e) Date Jan. 8, 1998 PCT Filed Feb. 27, 1997 PCT Pub. No. WO97 / 31990 PCT Pub. Date Sep. 4, 1997This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and / or an additive agent to raise its temperature to 250-350 DEG C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500 DEG C. It is maintained at this temperature until pyrolysis occurs. In order to obtain high-quality oil with a low boiling point, a first gas / liquid separation process separates the product obtained from the aforesaid pyrolysis into liquid high-boiling point oil, gaseous low-boiling point oil and low molecular-weight gases, and recirculates the liquid high-boiling point oil to the pyrolysis process, and a second gas / liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases. The first and second gas / liquid separation process are connected in sequence.

A method of crystallizing amorphous silicon on a glass substrate relies on deliberately heating the glass substrate above its strain point during processing, making low temperature glasses, such as soda lime glasses, ideal for such use. Since the glass is plastic above this temperature while the silicon remains elastic, the glass is forced to conform to the shape defined by the silicon once this temperature is exceeded. This process relaxes any stresses which might otherwise be created in the glass or film, as long as the glass temperature is above the strain point. As the glass temperature is reduced back below the strain point, the glass becomes progressively more rigid and stresses will begin to build up in the film and glass. When cooled slowly, the stress in the film and the glass can be controlled by appropriate selection of a thermal expansion coefficient of the glass relative to that of silicon, particularly those with linear expansion coefficients in the range 4-10 ppm / ° C. below the strain point.
