摘要： An excimer laser apparatus is provided with a compact high efficiency dust particle removal means which is capable of maintaining the windows clean with only a small volume of purging gas, and which prevents deterioration of aperture masks without having to increase the cavity length or risking the possibility of leakage from piping connections. The excimer laser apparatus uses, as dust particle removal means, filters (13a and 13b) made of metal or ceramic which is non-reactive with fluorine. A ground potential dust collector can be provided at a downstream side of a static dust particle remover, having an anode and a cathode, for collecting any dust particles which have passed through the static dust particle remover. In addition, clean laser medium gas can be introduced into subchambers (14a and 14b) through gas introducing passages (11a and 11b) provided in the walls of the housing (1) and then into the laser chamber (12) through labyrinths (8a and 8b) without disturbing the clean gas which stays near the internal surfaces of the windows (6a and 6b).

摘要： A buffer gas contained in a laser gas used for an ArF excimer laser mainly consists of He, and Xe is preferably added to the laser gas. Mixture piping divided by valves is disposed on piping running from a chamber to an excimer laser gas cylinder, the mixture piping and a Xe gas cylinder are connected, gas exhaust by a gas exhaust module and opening and closing of the valves are controlled by a gas controller to add a trace quantity of xenon gas to the excimer laser gas. Thus, to remedy a burst characteristic and a spike characteristic of the ultraviolet laser device by adding a trace quantity of xenon gas, the xenon gas can be supplied efficiently into the chamber without modifying existing laser gas supply equipment.

摘要： A laser apparatus comprises storage means for storing a power source voltage of each pulse at the time of continuous pulse oscillation for one cycle, with each voltage correlated with an identifier which specifies the respective pulse, and output control means for, when a pulse is generated, reading from the storage means the source voltage of a pulse having the same identifier, and performing pulse oscillation on the basis of the source voltage. Thus the influence of the spiking phenomenon during a burst mode operation is eliminated as much as possible, and thereby the accuracy of laser beam machining is still more improved.

摘要： Aimed at preventing a laser light beam profile from fluctuating, and by using the fact that there is a substantially proportional relation between the beam profile and the charging voltage as well as between the beam profile and the composition or the total pressure of the laser gases, an excimer laser device comprises a laser chamber containing laser gases which are excited by initiating an electric discharge in the laser chamber to output laser light, a beam profile detector for detecting a beam profile of the output laser light, and a controller for controlling a electric discharge voltage (excitation intensity) and composition or total pressure of the prescribed types of laser gases in such a way that the beam profile is shaped as desired based on detection results of the beam profile detector. An excimer laser feedback control circuit detects the output laser beam width and controls the beam width by controlling one or more of the laser voltage, composition of the laser gas, pressure or partial pressure of the laser gas, or feed rate of a laser gas. The laser gas may comprise a halogen, buffer, or rare gas.
