  • Patent number: 9263279
    Abstract: Features are fabricated on a semiconductor chip. The features are smaller than the threshold of the lithography used to create the chip. A method includes patterning a first portion of a feature (such as a local interconnect) and a second portion of the feature to be separated by a predetermined distance, such as a line tip to tip space or a line space. The method further includes patterning the first portion with a cut mask to form a first sub-portion (e.g., a contact) and a second sub-portion. A dimension of the first sub-portion is less than a dimension of a second predetermined distance, which may be a line length resolution of a lithographic process having a specified width resolution. A feature of a semiconductor device includes a first portion and a second portion having a dimension less than a lithographic resolution of the first portion.

  • Publication number: 20150242213
    Abstract: Various embodiments of methods and systems for flexible read only memory (“ROM”) storage of coded instructions in a portable computing device (“PCD”) are disclosed. Because certain instructions and/or data associated with a primary boot loader (“PBL”) may be defective or in need of modification after manufacture of a mask ROM component, embodiments of flexible ROM storage (“FRS”) systems and methods use a closely coupled one-time programmable (“OTP”) memory component to store modified instructions and/or data. Advantageously, because the OTP memory component may be manufactured “blank” and programmed at a later time, modifications to code and/or data stored in an unchangeable mask ROM may be accomplished via pointers in fuses of a security controller that branch the request to the OTP and bypass the mask ROM.
