It is a binary file format representing planar geometric shapes, text labels, and other information about the layout in hierarchical form (two-dimensional/2D CAD file format). The data can be used to reconstruct all or part of the artwork to be used in sharing layouts, transferring artwork between different tools, or creating photomasks .

Open Artwork System Interchange Standard (OASIS [3]) is a binary file format used for specification of data structures for photomask production. [4] It's used to represent a pattern an interchange and encapsulation format for hierarchical integrated circuit mask layout information produced during integrated circuit design that is further used for manufacturing of a photomask.
A process design kit (PDK) is a set of files used within the semiconductor industry to model a fabrication process for the design tools used to design an integrated circuit. The PDK is created by the foundry defining a certain technology variation for their processes.
For several years, the Semiconductor Industry Association (SIA) gave this responsibility of coordination to the United States, which led to the creation of an American style roadmap, the National Technology Roadmap for Semiconductors (NTRS). [5] The first semiconductor roadmap, published by the SIA in 1993.
The first practical application of semiconductors in electronics was the 1904 development of the cat's-whisker detector, a primitive semiconductor diode used in early radio receivers. Developments in quantum physics led in turn to the invention of the transistor in 1947 [ 7 ] and the integrated circuit in 1958.
A challenge most critical to analog IC design involves the variability of the individual devices built on the semiconductor chip. Unlike board-level circuit design which permits the designer to select devices that have each been tested and binned according to value, the device values on an IC can vary widely which are uncontrollable by the ...
STDF is a binary format, but can be converted either to an ASCII format known as ATDF or to a tab delimited text file. Decoding the STDF variable length binary field data format to extract ASCII text is non-trivial as it involves a detailed comprehension of the STDF specification, the current (2007) version 4 specification being over 100 pages ...
