An electrostatic chucking apparatus includes a movable member arranged for movement relative to an axial axis, at least one electrostatic chuck coupled to the movable member, and a stationary member. At least one moving insulated electrode is coupled to the movable member, and at least one stationary insulated electrode is coupled to the stationary member in an axial position corresponding to the at least one moving insulated electrode. A slip ring contact couples electrical energy from the at least one stationary insulated electrode to the at least one moving insulated electrode.

Apparatus and method to electrostatically chuck substrates to a moving carrier

A chucking apparatus and methods for coating a glass substrate using a vacuum deposition process are disclosed. In one or more embodiments, the chucking apparatus includes an ESC (ESC), a carrier disposed on the ESC, wherein the carrier comprises a first surface adjacent to the ESC and an opposing second surface for forming a Van der Waals bond with a third surface of a glass substrate, without application of a mechanical force on a fourth surface of the glass substrate opposing the third surface. In one or more embodiments, the method includes disposing a carrier and a glass substrate on an ESC, such that the carrier is between the glass substrate and the ESC to form a chucking assembly, forming a Van der Waals bond between the carrier and the glass substrate, and vacuum depositing a coating on the glass substrate.

Disclosed are synthetic silica glass body with a birefringence pattern having low fast axis direction randomness factor and glass reflow process. The glass reflow process comprises steps of: providing a glass tube having a notch; and thermally reflowing the glass tube to form a glass plate. The process can be advantageously used to produce fused silica glass plate without observable striae when viewed in the direction of optical axis. Also disclosed are optical members comprising the fused silica glass body and a process for reflowing glass cylinders.

Thermal reflow of glass and fused silica body

A method of making a fused silica plate includes providing a fused silica blank having a length, a longitudinal axis, and an outer diameter. The method further includes forming a slot in the fused silica blank which extends from the outer diameter to a location at or offset from a center of the fused silica blank and is substantially parallel to the longitudinal axis of the fused silica blank. The slot is defined by a concave surface located at or offset from the center of the fused silica blank, a first side surface extending between a first edge of the concave surface and the outer diameter of the fused silica blank, and a second side surface extending between a second edge of the concave surface and the outer diameter of the fused silica blank. At least one of the first and second side surfaces are connected to the concave surface by a chamfered surface. The method further includes rolling out the fused silica blank having the slot to form a fused silica plate.

Disclosed is a method for treating glass and crystalline inorganic materials whereby metal contamination during such process is inhibited. Such process includes treating the material in the presence of a purifying atmosphere comprising a cleansing gas. The process is especially advantageous for treating high purity fused silica glass for use in advanced lithographic devices.

Method for suppressing metal contamination in high temperature treatment of materials

A method of making a capillary splice includes applying pressure to a bore in a tube, applying heat to a portion of the tube to soften the portion of the tube, and forming a bubble within the bore in the heated portion under the influence of the pressure and heat. While forming the bubble, a diameter of the bore at the heated portion is measured to determine when the bubble has enlarged to a target size. When the bubble has enlarged to the target size, a force is applied along an axial axis of the tube to shape the bubble to a desired size.

Method for making capillary splice

A method of making glass tubing includes assembling together a first glass rod having at least one bore and a second glass rod having at least one bore to form a single glass unit, shaping an outer surface of the glass unit to a desired cross-section, and drawing the glass unit to form a glass tubing having a predetermined outer and inner dimension.
