  • Patent number: 10170548
    Abstract: A semiconductor device and process of making the same generally includes simultaneously forming nanosheet capacitors with nanosheet FET devices on the same substrate. The nanosheets in the capacitor have a width and are coupled to one another by sacrificial layers, wherein the sacrificial layers have a width smaller than the nanosheet width, and wherein the nanosheets and the sacrificial layers are conductively coupled to the substrate. The nanosheets in the FET devices are spaced apart and free of sacrificial layers. The nanosheets in the FET device have a width less than half the width of the nanosheets in the capacitor region.

  • Patent number: 7932167
    Abstract: A memory cell in an integrated circuit is fabricated in part by forming a lower electrode feature, an island, a sacrificial feature, a gate feature, and a phase change feature. The island is formed on the lower electrode feature and has one or more sidewalls. It comprises a lower doped feature, a middle doped feature formed above the lower doped feature, and an upper doped feature formed above the middle doped feature. The sacrificial feature is formed above the island, while the gate feature is formed along each sidewall of the island. The gate feature overlies at least a portion of the middle doped feature of the island and is operative to control an electrical resistance therein. Finally, the phase feature is formed above the island at least in part by replacing at least a portion of the sacrificial feature with a phase change material. The phase change material is operative to switch between lower and higher electrical resistance states in response to an application of an electrical signal.

  • Patent number: 7699996
    Abstract: A method for simultaneously forming multiple line-widths, one of which is less than that achievable employing conventional lithographic techniques. The method includes providing a structure which includes a memory layer and a sidewall image transfer (SIT) layer on top of the memory layer. Then, the SIT layer is patterned resulting in a SIT region. Then, the SIT region is used as a blocking mask during directional etching of the memory layer resulting in a first memory region. Then, a side wall of the SIT region is retreated a retreating distance D in a reference direction resulting in a SIT portion. Said patterning comprises a lithographic process. The retreating distance D is less than a critical dimension CD associated with the lithographic process. The SIT region includes a first dimension W2 and a second dimension W3 in the reference direction, wherein CD<W2<2D<W3.

  • Patent number: 7560692
    Abstract: A high quality electron microscopy sample suitable for electron holography is prepared by forming markers filled with TEOS oxide and by repeatedly applying multiple coats of an adhesive followed by a relatively low temperature cure after each application. The TEOS oxide marker is readily visible during the polish, has a similar polish rate as a semiconductor material, and reduces contamination during sample preparation. The repeated application of adhesives separated by relatively low temperature cures increases the adhesive strength of the adhesive material to the semiconductor material without making it too brittle. This results in an improved control and yield of the sample preparation process.
