Disclosed is a plasma processing device that provides an object to be treated with plasma treatment. A wafer as an object to be treated, which is attached on the upper surface of adhesive sheet held by a holder frame, is mounted on a stage. In a vacuum chamber that covers the stage therein, plasma is generated, by which the wafer mounted on the stage undergoes plasma treatment. The plasma processing device contains a cover member made of dielectric material. During the plasma treatment on the wafer, the holder frame is covered with a cover member placed at a predetermined position above the stage, at the same time, the wafer is exposed from an opening formed in the center of the cover member.

A resin coating applying apparatus includes a housing, a lid, a lid actuator for actuating the lid openably and closably with respect to the housing, a resin supply for supplying a solid resin to a workpiece, a vacuum pump for evacuating a processing space hermetically sealed by the housing and the lid, and an atmospheric vent valve for introducing atmospheric air into the processing space to cool the resin applied to the workpiece. The housing includes a holding table and a holding table actuator for moving the holding table upwardly and downwardly. The lid includes an upper table disposed opposite the holding table and movable relatively closely to the holding table to spread the resin supplied to the workpiece and coat the workpiece with the resin. When the lid is closed, it covers the opening in the housing to create the hermetically sealed processing space.

Plasma processing apparatuses, substrate bonding systems, and substrate bonding methods are provided. The plasma processing apparatus includes a plasma process chamber that includes a process space, a load-lock chamber connected to the process space, a first vacuum pump that adjusts a pressure of the load-lock chamber, a process gas supply that supplies the process space with a process gas, and an H.sub.2O supply that supplies the process space with H.sub.2O. The plasma process chamber includes a chuck that supports a substrate and a plasma electrode to which a radio-frequency (RF) power is applied.

Methods, systems, and apparatus for cleaning and drying a tape-frame substrate are provided. In embodiments, an apparatus for supporting a tape-frame substrate includes a chuck having a first side and a second side opposite the first side, the first side having a convex surface configured to support the tape-frame substrate; and a plurality of channels extending through the chuck and having outlets along the first side, wherein the plurality of channels are configured to dispense fluid from the outlets along the convex surface of the first side. In embodiments, a support system includes the chuck and a holder configured to mount a tape-frame substrate to the chuck. The plurality of channels are configured to dispense fluid from the outlets and between the tape-frame substrate and the convex surface of the chuck when the tape-frame substrate is mounted to the chuck.

A wafer separating apparatus is provided which includes a wafer supporting member having an upper surface on which a bonded wafer formed of two wafers bonded with each other is placed; an arm portion arranged outside of the wafer supporting member, the arm portion being movable closer to and away from a bonded portion of the bonded portion of the bonded wafer supported by the supporting portion; and an inflating portion provided in an distal end portion of the arm portion, the inflating portion being inflatable in a direction intersecting the upper surface of the wafer supporting member.

A fixture used in the manufacture of an eyepiece, to cut the eyepiece to a particular shape, and a method of using the fixture to cut the eyepiece to have a desired shape. Embodiments are directed to a configurable fixture to align, hold, and protect a plastic sheet (e.g., a wafer) while a laser cutting apparatus is cutting one or more eyepieces out of the wafer. During the cutting, the fixture protects the eyepieces from reflected laser light by providing voids around the laser cutting lines, and by supporting each eyepiece near its perimeter. The fixture can be quickly rearranged for different eyepieces, different eyepiece shapes, and/or different plastic sheet sizes.

A processing apparatus includes a chuck table for holding a workpiece, a processing unit for processing the workpiece held on the chuck table as supplying a processing water to the workpiece, and a water pan fixed to a bottom of the processing apparatus for receiving the processing water as a water leaked.

A method of manufacturing chips includes a preparing step of preparing a wafer unit in which a wafer having a plurality of devices formed thereon is affixed to a tape with a die-attach layer being interposed therebetween, the die-attach layer including fillers, and the devices are protected by a protective member and a face side of the wafer is exposed along the projected dicing lines, a wafer processing step of performing plasma etching on the wafer from the face side thereof to divide the wafer and expose the die-attach layer along the projected dicing lines, a die-attach layer processing step of performing plasma etching on the die-attach layer from the face side of the wafer, and a cleaning step of ejecting a fluid to the face side of the wafer to remove filler residuals along the projected dicing lines from the wafer unit.
