Abstract: Computer-implemented methods and systems for determining different process windows for a wafer printing process for different reticle designs are provided. One method includes generating simulated images illustrating how each of the different reticle designs will be printed on a wafer at different values of one or more parameters of the wafer printing process. The method also includes detecting defects in each of the different reticle designs using the simulated images. In addition, the method includes determining a process window for the wafer printing process for each of the different reticle designs based on results of the detecting step.

Abstract: A printing device wherein top frontal positioning of motor and drive train is avoided so that the size of the top portion can be reduced thereby improving the ability of the operator to view the alignment of a printable article in relation to the printer. The device includes a printer rack having a vertical support member and a base; a moving clamping piece movably mounted on the printer rack permitting the clamping piece to move towards and away from the base; a printer movably mounted on the clamping piece; a cam shaft rotatably mounted on the printer rack and provided thereon with a cylindrical cam for moving the printer towards and away from the vertical support member and further provided thereon with means for raising and lowering the clamping piece so that the clamping piece clamps the article during printing and releases the article upon completion of printing; and a motor mounted on the printer rack for turning the cam shaft.

Abstract: A time card printer comprising a plurality of type wheels rotatably mounted on a common supporting shaft and a plurality of printing rolls radially aligned with respective type wheels, the printing rolls being mounted on a common drive shaft which rotates in response to insertion of a time card and is parallel to the supporting shaft, each printing roll pressing the inserted time card against the type surface of the corresponding type wheel during rotation of the drive shaft, the printing rolls being moved against the corresponding type wheels one after the other.
