摘要： A plasma processing apparatus performs various plasma processings of a substrate having a large area in a semiconductor element manufacturing process, by using highly excited plasma generated at a low pressure under the application of RF power and a magnetic field. In this plasma processing apparatus, a gas is introduced into a vacuum chamber to be used as an ion source, RF power is applied to two electrodes having respective surfaces opposite to each other through the gas to thereby generate the plasma in the vacuum chamber, and a magnetic field is applied to the plasma from a magnetic field source arranged at a predetermined position. The intensity of the applied magnetic field is set to be 1.5 times or more the magnetic field intensity which causes electron cyclotron resonance to occur at the frequency f of the applied RF power. Particularly, when the frequency f of the RF power is 13.56 MHz, the magnetic field intensity is selected to be in the range from 25 gausses to 35 gausses.

摘要： Cluster particles including a plurality of molecules or atoms are prepared by a gas cluster method, are accelerated, and are then irradiated onto a diamond in a low pressure atmosphere, so that the unevenness surfaces of the diamond are smoothed with no damages in the diamond. The cluster particles are prepared by the steps of forming, ionizing, mass-separating, and accelerating cluster particles. The cluster particles with a certain energy are irradiated onto the surface of the diamond. Irradiated cluster particles collide with the surface of the diamond, and then break apart into each molecule or atom while changing momentum (direction and speed) or energy. Thus, the surface of the diamond is efficiently smoothed and etched.

摘要： An impurity doped SiC substrate 1 and SiC thin film 2 are irradiated with a laser light 5 having a wavelength longer than such a wavelength that a band edge absorption of a semiconductor is caused. The wavelength of the laser light 5 may be such a wavelength that an absorption is caused by a vibration by the bond of an impurity element and an element constituting the semiconductor, for example, a wavelength of 9 &mgr;m to 11 &mgr;m. Specifically, in the case where Al is doped in SiC, the wavelength of the laser light 5 may be within the range of 9.5 &mgr;m to 10 &mgr;m.

摘要： An optical system includes a semiconductor laser. The semiconductor laser is accommodated within a case. The case is formed with a window to pass through laser light emitted from the semiconductor laser. The laser light passed through the window comes to a collimator lens. Between semiconductor laser and the collimator lens is provided a light shield member having a pinhole to pass through the laser light having passed the window. Laser light made in a parallel luminous flux is outputted from the collimator lens. This laser light is deflected toward a main scanning direction by a deflector and further collected on a scanning surface by a light collector.

摘要： In a method of manufacturing a semiconductor device having an LDD structure, source gases for generating plural types of impurity ions exhibiting different molecular weights and different projected ranges in a target during impurity implantation are supplied to a plasma space, ionized, accelerated with a voltage, and implanted in a semiconductor region on the target substrate. In the case of manufacturing a top-gate transistor, a gate electrode on the semiconductor region has a sufficient thickness to serve as a mask. In the case of manufacturing a bottom-gate transistor, a mask and a resistor are used. An implantation angle is set to an optimum value as desired. Thereafter, the impurity is activated as desired. Thus, the semiconductor device having the LDD structure is manufactured by a single step of impurity implantation.
