Inventor: HAYASHI NOBUYUKI
IPC: H01L21/203
Filed: 1994-03-24
Abstract: PURPOSE:To securely form a metal compound thin film in high vacuum and enable fine control of the thin film growth rate and uniformity of the film structure, by exciting or activating a reactive agent with a radical beam in growing a single crystal thin film made of a metal nitride on a substrate using a molecular beam. CONSTITUTION:A high-quality single crystal film is produced using an electron cyclotron resonance plasma source as an excitation atom beam 3, and fine control of thin film growing conditions is enabled utilizing characteristics of the MBE method. Therefore, a composite film having satisfactory surface properties required to produce ultra-large scale integrated circuits can be produced using semiconductor and metal materials. In other words, excitation particles to be film forming atoms are introduced directly to the surface as beams of the same number of incidence and the same direction, thus efficiently causing reactions without excessively raising the temperature of the surface so that resulting compounds adhere to the surface. Thus, conditions for single crystal film growth, such as, crystalline nucleus growth and surface diffusion, can be controlled.

Filed: 1993-04-07
Abstract: PURPOSE:To provide the PLL circuit equipped with optimum convergent characteristics and frequency stability by changing convergent speed while depending on the characteristic of a low-pass filter(LPF) to change a cut-off frequency or the like based on a prescribed voltage supplied from a frequency/ voltage conversion part. CONSTITUTION:A phase comparator 1 detects phase difference between an input signal 10 and a feedback signal 12 and outputs a signal corresponding to phase difference to an LPF 2. A VCO 3 is controlled by a DC voltage from the LPF 2 and generates a prescribed clock output signal 11 based on a frequency selection signal 15. A frequency divider 4 divides the frequency of the signal 11 and changes a frequency dividing ratio based on the signal 15, and a frequency/voltage converting part (F/V) 5 inputs the signal 11 and outputs a voltage 16 corresponding to the frequency. As a result, the F/V 5 supplies the prescribed voltage signal 16 to the LPF 2 corresponding to the frequency of the output signal 11, namely, the oscillation frequency. The LPF 2 changes the transmission characteristic such as the cut-off frequency and as a result, the PLL circuit changes loop sensitivity and shortens the convergent time of frequency lock.

Abstract: PURPOSE:To block the influence of disturbance light without sacrifice of mounting/ demounting performance of an object by disposing a shade cover while dividing into the light source side and light receiving side in order to block the disturbance light, condensing the diffused light through a convex lens and passing only the parallel light through an aperture and receiving by means of an image sensor. CONSTITUTION:Light from a light source 1 impinges on a transmission diffuser 2 to produce a diffused light. A cover 3 prevents a disturbance light from impinging on the diffuser 2. The diffused light 4 is condensed through a convex lens 5 and passed through a shade 6 having an aperture 7 thus passing only such component as parallel with the optical axis of the lens 5 through the aperture 5. In other words, only the shade part 12 formed by an object 11 passes through the shade 6 and forms a shade on an image sensor 8. A light shielding chamber 9 shields the light receiving part from disturbance light. An operating section 10 measures the outer diameter D of the object 11 based on a measurement data of peak position when the primary derivative of intensity distribution of light received by the sensor 8 is subjected to curve regression, the center of gravity of the primary derivative, or the zero point when the secondary derivative is subjected to curve regression.

Abstract: PURPOSE:To provide simplification of a stage and a reduction of cost by forming an Al film only to the required point of a metallic substrate by a laser beam while passing a plating gas contg. Al then blanking the substrate to a prescribed pattern. CONSTITUTION:The beam 5 generated by a laser oscillator 1 enters a vessel 11 through a transmission window 4 regulated by an output regulator 2 and irradiated to an Fe-Ni alloy bar 8 as a substrate. The beam 5 is moved by a scanning device 3 so as to be irradiated to the prescribed position of the bar 8 which is the substrate. The inside of the vessel 11 is evacuated to a vacuum through an evacuating hole 10 and the plating gas such as Al(CH3) or the like is introduced therein through a gas introducing port 9. The film consisting of Al is formed on the bar 8 subjected to the laser irradiation and thereafter the bar 8 is blanked to a prescirbed pattern, by which the lead frame is obtd. The stage for masking and removing the Al by dissolution is thus eliminated, by which the stage is simplified and the cost is reduced.
