Abstract: A bonding apparatus includes a first holder, a second holder, a first interferometer, a housing, a gas supply and an airflow control cover. The first holder attracts and holds the first substrate. The second holder attracts and holds the second substrate. The first interferometer measures, by radiating light to the second holder or a first object which is moved along with the second holder in the first horizontal direction, a distance to the second holder or the first object in the first horizontal direction. The housing accommodates therein the first holder, the second holder and the first interferometer. The gas supply is provided at a lateral side of the housing, and supplies a gas into the housing. The airflow control cover is provided within the housing, and redirects a part of a flow of the gas supplied from the gas supply toward a first path of the light.

Abstract: A coating apparatus includes: a slit nozzle including a retention chamber that retains the coating material; a moving mechanism that moves the slit nozzle; a pressure regulation unit that regulates a pressure inside the retention chamber; and a control unit that controls the moving mechanism and the pressure regulation unit to relatively move the slit nozzle with respect to the substrate while changing the pressure inside the retention chamber toward an atmospheric pressure from a negative pressure, wherein the control unit is configured to control the pressure regulation unit so that a change in the pressure inside the retention chamber in a start zone including a coating start position and an end zone including a coating end position becomes slower than a change in the pressure inside the retention chamber in a middle zone except the start zone and the end zone.

Abstract translation: 涂布装置包括：狭缝喷嘴，其包括保持涂料的保留室; 使狭缝喷嘴移动的移动机构; 压力调节单元，其调节保持室内的压力; 以及控制单元，其控制所述移动机构和所述压力调节单元，以使所述狭缝喷嘴相对于所述基板相对移动，同时将所述保持室内的压力从负压变为大气压，其中，所述控制单元被配置为控制 压力调节单元，使得在包括涂层开始位置和包括涂层终止位置的端部区域的起始区域内的保持室内的压力变化比在中间区域中的保持室内部的压力变化慢，除了 起始区和结束区。
