A pellicle mask assembly includes a mask, a pellicle frame, and a pellicle membrane. The pellicle frame has a bottom side attached to the mask, and a top side covered by the pellicle membrane. The pellicle frame includes a coating on its inner surface and the coating is configured to monitor a change of environment inside the pellicle mask assembly. In embodiments, the change of environment includes increased humidity and/or increased chemical ion density inside the pellicle mask assembly. Methods of making and using the pellicle mask assembly are also disclosed.

A pellicle is provided that includes a pellicle film, a pellicle frame having the pellicle film stretched over one end face thereof and having the other end face open, and a pressure-sensitive adhesion layer for adhering the pellicle frame to a mask, the pressure-sensitive adhesion layer being provided on an inner peripheral face of the pellicle frame, and the pressure-sensitive adhesion layer being capable of adhering to a side face of a mask having a mask image on a front face. There are also provided a method of mounting a pellicle that includes fixing to a side face of a mask an inner peripheral face of a pellicle frame of a pellicle that includes a pellicle film and a pellicle frame having the pellicle film stretched over one end face thereof and having the other end face open, a method of mounting a pellicle that includes adhering the pellicle to a side face of the mask that is inclined in going from the reverse face of the mask toward the front face where the mask image is provided, thus adhering the side face of the mask to the pellicle frame inner peripheral face, a pellicle-equipped mask that includes the pellicle adhered to a mask, and a mask that includes a side face that is inclined in going toward the front face where a mask image is provided.

An unfolded book, placed upon a copy machine, can have its two exposed pages reproduced without a shadow between the two pages using this invention. A bar formed in the shape of a "T" is placed, with the "T" upside down, and with the shaft of the "T" resting along the crease of the book between the two pages. Slidable stop plates at each end of the bar can be used to snuggle the book with the bar. Variations in the shape of the arms of the "T" and in the shape of the terminations of the arms are presented.

A magnet is provided on either a negative film mask or a negative film mask table of a negative film mask apparatus, and a magnetic material is provided on the other of these. When the negative film mask in which a negative film has been loaded is placed on the negative film mask table, the negative film mask is held in place by a magnetic force. The negative film mask apparatus is provided with a stopper. The stopper is adapted to press a closely-contacting member against a sliding surface of the negative film mask table when necessary, thereby preventing the negative film mask from sliding. The closely-contacting member is made of a material such as rubber so that it can closely contact a sliding surface of the negative film mask table. Further, a magnetic member is included in the stopper. The stopper generates a large frictional force utilizing pressing force and magnetic force. Therefore, the negative film mask can be stably held in place in a state in which the negative film mask and the negative film mask table are inclined. Also, the large frictional force makes it possible to stably hold the negative film mask in place against a magnetic force which acts on the negative film mask in a horizontal direction.

A MACHINE FOR COPYING DATA TO BE INCORPORATED IN TAX STATEMENTS, OR THE LIKE. THE DATA IS THE FORM OF INFORMATION CARRIED ON SETS F STRIPS SLIDABLY-MOUNTED ON A SUPPORTING FEEDER PLATE. THE MACHINE HAS A SEAT TO RECEIVE THE LOADED FEEDER PLATE. THE SEAT IS ALIGNED WITH A FIXED-POSITIONING PLATE LOCATED OVER THE EXPOSURE AREA OF A PHOTO-COPYING MACHINE. ANOTHER SEAT ON THE OPPOSITE SIDE OF THE POSITIONING PLATE CONTAINS A REMOVABLE ALIGNED RECEIVING PLATE ON WHICH THE STRIPS ARE SLIDABLY-RECEIVED AFTER THEY HAVE BEEN COPIED. THE STRIPS HAVE END LUGS ENGAGEABLE BY ELECRICALLY-CONTROLLED DRIVE PAWLS CARRIED ON CARRIAGES CONNECTED TO SETS OF ENDLESS SPROKET CHAINS MOUNTED ON THE CHASSIS OF THE MACHINE. THE STRIPS HAVE END MARKERS SENSED BY PHOTOELECTRIC SENSING ELEMENTS MOUNTED ON THE CARRIAGES CONNECTED TO ONE SET OF ENDLESS SPROCKET CHAINS. A PROGRAMMING ELECTRICAL CIRCUIT OPERATES THE SPROCKET CHAIN MOTORS AND DRIVE ELEMENTS TO SEQUENTIALLY MOVE SETS OF RELATED SRIPS TO SPECIFIC COPYING POSITIONS ON THE POSITIONING PLATE, AND THENCE TO THE RECEIVING PLATE. LIMIT SWITCHES CONTROL THE CYCLE OF OPERATIONS SO THAT THE MACHINE STOPS WHEN ALL THE INFORMATION STRIPS HAVE BEEN COPIED AND DELIVERED TO THE RECEIVING PLATE.
摘要:
A mask for a lithographic apparatus is disclosed, the mask having a patterned region bearing a pattern to be transferred onto a substrate and a border surrounding the patterned region, wherein at least part of the border has a plurality of elements, the dimensions of the elements being such that, during use, they would not be resolved at the substrate. Also, a lithographic apparatus is disclosed, the apparatus having a projection system, a substrate table arranged to hold a substrate, and a patterning device having a patterned region which bears a pattern to be transferred using a radiation beam via the projection system onto the substrate, at least part of a border surrounding the patterned region comprising a plurality of elements arranged to direct radiation onto the substrate, the dimensions of the elements such that, during use, they are not resolved at the substrate.
摘要:
The feeding of documents through optical equipment (such as OCR scanners, microfilming equipment, etc.) is facilitated by providing pocketed document carriers. Each document carrier has a transparent plastic film first part and a white paper second part, with adhesive along some of the edges between the parts defining a pocket, with at least one of the edges open to allow the insertion of one or more documents into the pockets. The carriers, containing the documents, are intermixed in a desired sequence with documents that are full size (e.g., having a size substantially the same as the document carriers) for automatic or hand feeding through the optical equipment. A number of different pocket configurations may be provided, including a duplex construction.
