摘要： A method is described for fabricating and antifuse structure (100) integrated with a semiconductor device such as a FINFET or planar CMOS devise. A region of semiconducting material (11) is provided overlying an insulator (3) disposed on a substrate (10); an etching process exposes a plurality of corners (111-114) in the semiconducting material. The exposed corners are oxidized to form elongated tips (111t-114t) at the corners; the oxide (31) overlying the tips is removed. An oxide layer (51), such as a gate oxide, is then formed on the semiconducting material and overlying the corners; this layer has a reduced thickness at the corners. A layer of conducting material (60) is formed in contact with the oxide layer (51) at the corners, thereby forming a plurality of possible breakdown paths between the semiconducting material and the layer of conducting material through the oxide layer. Applying a voltage, such as a burn-in voltage, to the structure converts at least one of the breakdown paths to a conducting path (103, 280).

摘要： Disclosed is an integrated circuit with multiple semiconductor fins having different widths and variable spacing on the same substrate. The method of forming the circuit incorporates a sidewall image transfer process using different types of mandrels. Fin thickness and fin-to-fin spacing are controlled by an oxidation process used to form oxide sidewalls on the mandrels, and more particularly, by the processing time and the use of intrinsic, oxidation-enhancing and/or oxidation-inhibiting mandrels. Fin thickness is also controlled by using sidewalls spacers combined with or instead of the oxide sidewalls. Specifically, images of the oxide sidewalls alone, images of sidewall spacers alone, and/or combined images of sidewall spacers and oxide sidewalls are transferred into a semiconductor layer to form the fins. The fins with different thicknesses and variable spacing can be used to form a single multiple-fin FET or, alternatively, various single-fin and/or multiple-fin FETs.

摘要： Standard photolithography is used to pattern and fabricate a final polysilicon wafer imaged structure which is smaller than normal allowable photo-lithographic minimum dimensions. Three different methods are provided to produce such sub-minimum dimension structures, a first method uses a photolithographic mask with a sub-minimum space between minimum size pattern features of the mask, a second method uses a photolithographic mask with a sub-minimum widthwise jog or offset between minimum size pattern features of the mask, and a third method is a combination of the first and second methods. Each of the three methods can be used with three different embodiments, a first embodiment is a polysilicon E-Fuse with a sub-minimum width polysilicon fuse line, a second embodiment is a work function altered/programmed self-aligned MOSFET E-Fuse with a sub-minimum width fuse line, and a third embodiment is a polysilicon MOSFET E-Fuse with a sub-minimum width fuse line which is programmed with a low trigger voltage snapback.

摘要： A method and structure is disclosed for a transistor having a gate, a channel region below the gate, a source region on one side of the channel region, a drain region on an opposite side of the channel region from the source region, a shallow trench isolation (STI) region in the substrate between the drain region and the channel region, and a drain extension below the STI region. The drain extension is positioned along a bottom of the STI region and along a portion of sides of the STI. Portions of the drain extension along the bottom of the STI may comprise different dopant implants than the portions of the drain extensions along the sides of the STI. Portions of the drain extensions along sides of the STI extend from the bottom of the STI to a position partially up the sides of the STI. The STI region is below a portion of the gate. The drain extension provides a conductive path between the drain region and the channel region around a lower perimeter of the STI. The drain region is positioned further from the gate than the source region.

摘要： The present invention relates to a programmable semiconductor device, preferably a FinFET or tri-gate structure, that contains a first contact element, a second contact element, and at least one fin-shaped fusible link region coupled between the first and second contact elements. The second contact element is laterally spaced apart from the first contact element, and the fin-shaped fusible link region has a vertically notched section. A programming current flowing through the fin-shaped fusible link region causes either significant resistance increase or formation of an electric discontinuity in the vertically notched section. Alternatively, the vertically notched section may contain a dielectric material, and application of a programming voltage between a gate electrode overlaying the vertically notched section and one of the contact elements breaks down the dielectric material and allows current flow between the gate electrode and the fin-shaped fusible link region.

摘要： An eFuse begins with a single crystal silicon-on-insulator (SOI) structure that has a single crystal silicon layer on a first insulator layer. The single crystal silicon layer is patterned into a strip. Before or after the patterning, the single crystal silicon layer is doped with one or more impurities. At least an upper portion of the single crystal silicon layer is then silicided to form a silicided strip. In one embodiment the entire single crystal silicon strip is silicided to create a silicide strip. Second insulator(s) is/are formed on the silicide strip, so as to isolate the silicided strip from surrounding structures. Before or after forming the second insulators, the method forms electrical contacts through the second insulators to ends of the silicided strip. By utilizing a single crystal silicon strip, any form of semiconductor, such as a diode, conductor, insulator, transistor, etc. can form the underlying portion of the fuse structure. The overlying silicide material allows the fuse to act as a conductor in its unprogrammed state. However, contrary to metal or polysilicon based eFuses which only comprise an insulator in the programmed state, when the inventive eFuse is programmed (and the silicide is moved or broken) the underlying semiconductor structure operates as an active semiconductor device.
