    摘要: An excimer laser chamber device may include: a the laser chamber; a first electrode provided in the laser chamber; a second electrode provided in the laser chamber to face the first electrode; an electrode holder provided in the laser chamber to be connected to a high voltage; at least one connecting terminal including a first anchored portion anchored to the first electrode and a second anchored portion anchored to the electrode holder, the at least one connecting terminal being configured to electrically connect the first electrode and the electrode holder; a guide member held by the electrode holder, the guide member being configured to position the first electrode in a direction substantially perpendicular to both a direction of electric discharge between the first electrode and the second electrode and a longitudinal direction of the first electrode; and an electrode-gap-varying unit configured to move the first electrode in a direction substantially parallel to the direction of electric discharge.
