  • Publication number: 20200200114
    Abstract: A method of controlling an injector driving circuit that may include a first field effect transistor (FET) that opens and closes a driving power supply to an injector, a second FET having a pulse width modulation control function for supplying a starting current to the injector to open a valve and then supplying a driving current for maintaining an opening driving state to the injector, and a Zener diode. The method may include increasing a valve opening torque to open the injector via turning ON both the first and second FET to obtain a maximum current during a cold start or when an injector valve sticks, turning OFF the second FET before closing the injector, and preventing damage to the Zener diode due to a back electromotive voltage from the injector provided when the valve is closed via turning OFF the first FET after a predetermined amount of time elapses.

  • Patent number: 10643850
    Abstract: A PSG film, which is a silicon dioxide thin film containing phosphorus as a dopant, is formed on the surface of a semiconductor wafer. The semiconductor wafer having the PSG film formed thereon is kept at a predetermined heating temperature by light radiation from halogen lamps in the atmosphere containing hydrogen for 1 second or longer, so that the dopant is diffused from the PSG film into the surface of the semiconductor wafer. In addition, the flashing light is radiated to the semiconductor wafer for the radiation time shorter than 1 second to heat the surface of the semiconductor wafer to the target temperature so as to activate the dopant. When the PSG film is heated in the atmosphere containing hydrogen, a diffusion coefficient of the dopant contained in the PSG film becomes high; therefore, the dopant can be efficiently diffused from the PSG film into the semiconductor wafer.

  • Publication number: 20200066532
    Abstract: A gallium nitride (GaN) substrate is injected with magnesium as a p-type dopant. The GaN substrate undergoes preheating through irradiation with light from halogen lamps in an atmosphere containing nitrogen and hydrogen, and further undergoes heating to a high temperature for a super-short time through irradiation with flashes of light from flash lamps. Heating the GaN substrate in the atmosphere containing nitrogen and hydrogen complements removed nitrogen, thus preventing nitrogen shortage. Such a heating process also enables heat treatment while supplying hydrogen to the GaN substrate. The heating process further enables crystal defects in the GaN substrate to be recovered. With these effects, the p-type dopant injected into the GaN substrate is activated with high efficiency.

  • Patent number: 10437153
    Abstract: A substrate having a surface on which a resist film is formed and that has undergone pattern exposure processing and development processing is conveyed into a chamber and held by a holding plate. The surface of the substrate W held by the holding plate is irradiated with flash light emitted from flash lamps. The spectral distribution of the flash light has a peak in a wavelength range of 200 nm to 300 nm. The spectral distribution of the flash light also shows that the relative intensity at a wavelength of 300 nm is 20% or more higher than that at a wavelength of 500 nm. Since the resist film absorbs ultraviolet rays, the resist film can be selectively heated by irradiating the resist film with flash light that includes a large number of wavelength components in the ultraviolet region.
