In photolithography, several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set. A curvilinear photomask has patterns with curves, which is a departure from conventional photomasks which only have patterns that are completely vertical or horizontal, known as manhattan geometry.
The result is most typically merged into the bottom layer using "simple" (b over a) alpha compositing (making the actual formula (,) = (,)), but other Porter-Duff operations are possible. [3] The compositing step results in the top layer's shape, as defined by its alpha channel, appearing over the bottom layer.
Instead of using a program, Pepper recommends making an initial sketch on paper. Instead of scanning the sketch and tracing it freehand in the computer, Pepper states: "Those proficient with a graphic tablet and stylus could make the following changes directly in CorelDRAW by using a scan of the sketch as an underlay and drawing over it.
The term tapeout currently is used to describe the creation of the photomask itself from the final approved electronic CAD file. Designers may use this term to refer to the writing of the final file to disk or CD and its subsequent transmission to the semiconductor foundry; however, in current practice the foundry will perform checks and make modifications to the mask design specific to the ...

Path-Offsets; Outset, Inset, Linked or Dynamic: can create a Linked or Dynamic (unlinked) Inset and or an Outset of an existing path which can then be fine tuned using the given Shape or Node tool. Creating a Linked Offset of a path will update whenever the original is modified. Making symmetrical (i.e., picture frame) graphics easier to edit.
