It is an object of the present invention to provide a method for manufacturing a semiconductor device, capable of keeping a peeling layer from being peeled from a substrate in the phase before the completion of a semiconductor element and peeling a semiconductor element rapidly. It is considered that a peeling layer tends to be peeled from a substrate because the stress is applied to a peeling layer due to the difference in thermal expansion coefficient between a substrate and a peeling layer, or because the volume of a peeling layer is reduced and thus the stress is applied thereto by crystallization of the peeling layer due to heat treatment. Therefore, according to one feature of the invention, the adhesion of a substrate and a peeling layer is enhanced by forming an insulating film (buffer film) for relieving the stress on the peeling layer between the substrate and the peeling layer before forming the peeling layer over the substrate.

The object of the present invention is to provide a laser irradiation apparatus being able to enlarge the beam spot to a large degree compared with that of the CW laser, to suppress the thermal damage to the glass substrate, and to form an aggregation of crystal grains including a single crystal extending long in a scanning direction by growing the crystal continuously in the scanning direction. The laser irradiation of the present invention comprises a pulsed laser oscillator, a non-linear optical element for converting the wavelength of the laser light emitted from the pulsed laser oscillator, and an optical system for condensing the laser light whose wavelength is converted on a semiconductor film, wherein the pulsed laser oscillator has a repetition rate in the range of 10 MHz to 100 GHz.

A technological process for preparing ultra-long single-wall continuous nanometre carbon tubes by the vertical floating catalytic cracking method includes such steps as preparing reaction solution from n-hexane as carbon source, ferrocene as catalyst and thiophene as additive, introducing it in the form of vapour along with hydrogen gas into a reactor for catalytic cracking. Under specific technological parameters, ultra-long cord-shape single-wall nm carbon tube bundle can be obtained, the tubes have good orientation, their purity up to 85%, they are continuous and straight with length up to20 cm (length to diameter ratio greater than 108). The said method only needs one vertical electric furnace and no need of pre-reduction. Its advantages include good orientation performance, high purity, long length, simple operation and low cost.

A high frequency magnetic thin film characterized by comprising a first layer made of a T-L composition (here, T is Fe or FeCo, and L is one or more of C, B, and N) and a second layer comprising a Co-based amorphous alloy arranged on either of the surfaces of the first layer. The high frequency magnetic thin film is a multilayer film of a plurality of the first layers and a plurality of the second layers or desirably is a multilayer film of alternately laminated first and second layers. The high frequency magnetic thin film of the present invention exhibits the properties such that the real part (μ′) of the complex permeability is 400 or more at 1 GHz, a quality factor Q (Q=μ′ / μ″) is 4 or more, and a saturation magnetization is 14 kG (1.4T) or more.

The present invention discloses a device for growth of a carbon nano-tube aerogel. The device comprises a main reaction cavity and a collection box, wherein the main reaction cavity is provided with an air inlet and an air outlet formed opposite to the air inlet; the collection box is communicated with the main reaction cavity; at least one secondary reaction cavity communicated with the main reaction cavity is sleeved in the main reaction cavity, the secondary reaction cavities are formed close to the air inlet of the main reaction cavity, and the length of each of the secondary reaction cavities in the axial direction of the main reaction cavity is less than that of the main reaction cavity. Compared with the prior art, the defect that a single reaction cavity is taken as a reaction chamber for the growth of the carbon nano-tube is overcome by virtue of sleeving the secondary reaction cavities in the main reaction cavity, so that not only is continuous and uniform carbon nano-tube aerogel generated, but also the yield of the carbon nano-tube aerogel is greatly improved by enlarging the tube diameter of the reaction chamber. The production cost is saved, the production period is shortened, and the industrial production of the carbon nano-tube aerogel becomes probable.
