  • Publication number: 20130203269
    Abstract: A first flash heating is performed in which a lower flash lamp irradiates a back surface of a semiconductor wafer with flashes of light, so that heat conduction from the back surface to a surface of the semiconductor wafer raises the temperature of the surface from the room temperature to an intermediate temperature. Then, a second flash heating is performed in which an upper flash lamp irradiates the surface of the semiconductor wafer with flashes of light, to raise the temperature of the surface of the semiconductor wafer from the intermediate temperature to a target temperature. Since only the irradiation with flashes of light emitted from the lower flash lamp and the upper flash lamp is used to cause the semiconductor wafer having the room temperature to reach the target temperature, all heat treatments can be completed in an extremely short time of one second or less.

  • Publication number: 20130199578
    Abstract: A substrate processing apparatus and a substrate processing method are capable of restraining or preventing the generation of streaky particles on a substrate surface by excellent removal of a rinsing liquid therefrom. The substrate processing apparatus has a substrate inclining mechanism for inclining a substrate held by a substrate holding mechanism. After a rinsing liquid has been supplied onto a substrate to form a liquid mass, the substrate is inclined at a small angle by the substrate inclining mechanism. Then, the liquid mass is downwardly moved without being fragmented and then falls down without leaving minute droplets on the substrate top. Thereafter, the substrate is returned to a horizontal posture and then dried.

  • Publication number: 20130167877
    Abstract: In a substrate processing apparatus, a liquid film of a supercooled liquid of pure water is formed on the upper surface of a substrate and then cooled with cooling gas into a frozen film. The temperature of the liquid film is lower than the freezing point of pure water, and thus the liquid film is in an easy-to-freeze state. Thus, the time required to freeze the liquid film can be shortened. Even if the temperature of the cooling gas is increased, the liquid film can be speedily frozen as compared with the case in which a liquid film is formed of pure water having a temperature higher than its freezing point. Thus, heat insulating facilities such as piping that supply cooling gas can be simplified. This results in a reduction of the cooling cost required to freeze the liquid film.

  • Publication number: 20130167876
    Abstract: A substrate processing apparatus (1) includes a bath body (11), cover members (12), processing liquid nozzles (31) for ejecting an SPM liquid like a shower, and gas nozzles (32) for ejecting nitrogen gas. The processing liquid nozzles eject a processing liquid (91) onto substrates (9) from sidewalls (111) of the bath body (11). By ejecting gas toward lower surfaces of the cover members from the gas nozzles before the substrates are loaded into the bath body, it is possible to remove droplets of the processing liquid deposited on the lower surfaces of the cover members during the previous processing of the substrates or during a temperature control where the processing liquid is ejected from the processing liquid nozzles. It is thereby possible to prevent or reduce deposition of droplets of the processing liquid dropped onto the substrates immediately after being loaded into the bath body.

  • Patent number: 8461033
    Abstract: A light-emission output of a flash lamp for performing a light-irradiation heat treatment on a substrate in which impurities are implanted is increased up to a target value L1 over a period of time from 1 to 100 milliseconds, is kept for 5 to 100 milliseconds within a fluctuation range of plus or minus 30% from the target value L1, and is then attenuated from the target value L1 to zero over a period of time from 1 to 100 milliseconds. That is, compared with conventional flash lamp annealing, the light-emission output of the flash lamp is increased more gradually, is kept to be constant for a certain period of time, and is then decreased more gradually. As a result, a total heat amount of a surface of the substrate increases compared with the conventional case, but a surface temperature thereof rises more gradually and then drops more gradually compared with the conventional case.

  • Patent number: 8447177
    Abstract: A capacitor, a coil, a flash lamp, and a switching element such as an IGBT are connected in series. A controller outputs a pulse signal to the gate of the switching element. A waveform setter sets the waveform of the pulse signal, based on the contents of input from an input unit. With electrical charge accumulated in the capacitor, a pulse signal is output to the gate of the switching element so that the flash lamp emits light intermittently. A change in the waveform of the pulse signal applied to the switching element will change the waveform of current flowing through the flash lamp and, accordingly, the form of light emission, thereby resulting in a change in the temperature profile for a semiconductor wafer.

  • Patent number: 8436885
    Abstract: A light from a laser light source (11) is collected at a position of a slit (125a) in a vertical direction by a first optical system (12a) to form an intermediate image which is long in a horizontal direction corresponding to an arrangement direction of light modulator elements. An undesired light such as side lobes which appear on the both sides of the intermediate image in the vertical direction is blocked by a slit (125a) and the intermediate image is reformed by a second optical system (12b), to direct a liner illumination light onto the spatial light modulator (13). Thus, in a state where moving ribbons are sagged and first order diffracted lights are emitted in a light modulator element, it is possible to prevent a zeroth order light from being emitted from both end portions of ribbons, to thereby enhance contrast of the signal light.
