A dis-pellicle tool or pellicle removal tool that includes one or more clamp structures that each include a respective group of pins. The respective pins of the groups of pins of the one or more clamp structures are configured to, in operation, be inserted into holes that are present within a pellicle frame of a pellicle. Once the respective pins of the groups of pins are inserted into the holes of the pellicle frame, a removal force may be applied to the pellicle frame to remove the pellicle from a photomask to which the pellicle is coupled to by an adhesive, glue, or some other similar type of coupling material.

Pellicle, pellicle removal tool, and method of utilizing pellicle and pellicle removal tool

A pellicle includes a frame configured to attach to a photomask, wherein the frame includes a vent hole. The pellicle further includes a filter covering the vent hole, wherein the filter directly connects to an outer surface of the frame. The pellicle further includes a membrane extending over a top surface of the frame. The pellicle further includes a mount between the frame and the membrane, wherein the mount is attachable to the frame by an adhesive.

Pellicle having vent hole

A flexible display device includes a base film, a display panel on the base film, a protective film on a surface of the display panel away from the base film, and an adhesive layer. An area of the protective film is less than that of the display panel. The adhesive layer and the protective film has an overlapping portion. The adhesive layer has a thickness and Young's modulus between 10 and 500 μm and between 0.1 and 10 GPa, respectively. A side edge of the base film, a side edge of the display panel, and a side edge of the adhesive layer are substantially aligned.

Flexible display device and manufacturing method thereof

An apparatus for removing a pellicle frame from a photomask includes a heater configured to soften an adhesive between the pellicle frame and the photomask; a shower head including a plate, a central region of the plate is configured to overlap with a pattern area of the photomask, and a periphery region of the plate is configured to provide a flow from the periphery region of the plate toward the pellicle frame and the adhesive; and a gripper configured to secure the pellicle frame against the flow and remove the adhesive and the pellicle frame from the photomask. A method of removing a pellicle frame, includes providing a plate overlapped with a pattern area of the photomask; providing a flow from the plate toward the pellicle frame and an adhesive; securing the pellicle frame; soften the adhesive; and leveraging the pellicle frame to remove the adhesive and the pellicle frame.

Apparatus for removing a pellicle frame from a photomask and the method thereof

A method of testing a photomask assembly includes placing the photomask assembly into a chamber, wherein the photomask assembly includes a pellicle attached to a first side of a photomask. The method further includes exposing the photomask assembly to a radiation source having a wavelength ranging from about 160 nm to 180 nm in the chamber to accelerate haze development, wherein the exposing of the photomask assembly includes illuminating an entirety of an area of the photomask covered by the pellicle throughout an entire illumination time and illuminating a frame adhesive attaching the pellicle to the photomask. The method further includes detecting haze of the photomask following exposing the photomask assembly to the radiation source. The method further includes predicting performance of the photomask assembly during a manufacturing process based on the detected haze of the photomask following exposing the photomask assembly to the radiation source.

Method of accelerated hazing of mask assembly

A flexible display device includes a base film, a display panel on the base film, a protective film on a surface of the display panel away from the base film, and an adhesive layer. An area of the base film is substantially identical to that of the display panel. An area of the protective film is less than that of the display panel. The adhesive layer is located on the surface of the display panel away from the base film. The adhesive layer and the protective film include an overlapping portion. The adhesive layer has a thickness and Young's modulus between 10 and 500 &#x3bc;m and between 0.1 and 10 GPa, respectively. A side edge of the base film, a side edge of the display panel, and a side edge of the adhesive layer are substantially aligned. A manufacturing method of a flexible display device is also provided.

An apparatus for removing a pellicle frame from a photomask includes a heater, a shower head, and a gripper. The heater is configured to soften a portion of an adhesive between the pellicle frame and the photomask. The shower head facing to the heater and configured to provide a flow from a patterned area of the photomask toward the pellicle frame and the adhesive. The gripper is configured to secure the pellicle frame against the flow and to remove the adhesive and the pellicle frame from the photomask. A method of removing a pellicle frame from a photomask includes providing a flow from a pattern area of the photomask toward the pellicle frame and an adhesive; securing the pellicle frame in a force-transmitting manner against the flow; soften at least a portion of the adhesive; and leveraging the pellicle frame to remove the adhesive and the pellicle frame.

In a method of cleaning a photomask, a wiper tape is guided from a wiper tape supplying reel, over a cleaning head, and then onto a wiper tape collecting reel. A section of the wiper tape over the cleaning head is brought into contact with an adhesive residue on a surface of the photomask. A relative movement is caused between the photomask and the section of the wiper tape to remove the adhesive residue from the surface of the photomask.

Cleaning module, cleaning apparatus and method of cleaning photomask

A method of removing a pellicle from a photomask includes removing a portion of a membrane from a pellicle frame, wherein the pellicle frame remains attached to the photomask following the removing of the portion of the membrane. The method further includes removing the pellicle frame from the photomask. The method further includes cleaning the photomask.

Pellicle removal method

A display, including a supporting layer and a flexible display panel, is provided. The supporting layer has at least two extending sections and at least one bending section, connected therebetween and adapted to be bent along an axis as a rotation axis. The supporting layer has at least one groove at the bending section and at least one indentation at a bottom surface of the groove. An extending direction of the groove is parallel to the axis. An extending direction of the indentation is not parallel to the axis. The supporting layer has a first thickness at each extending section, a second thickness at the groove, and a third thickness at the indentation. The first, second, and third thicknesses are different from one another. The flexible display is disposed on the supporting layer. The groove and the flexible display are respectively located on two opposite sides of the supporting layer.
