    Abstract: Selective transfer of dies including semiconductor devices to a target substrate can be performed employing local laser irradiation. Coining of at least one set of solder material portions can be employed to provide a planar surface-to-surface contact and to facilitate bonding of adjoining pairs of bond structures. Laser irradiation on the solder material portions can be employed to sequentially bond selected pairs of mated bonding structures, while preventing bonding of devices not to be transferred to the target substrate. Additional laser irradiation can be employed to selectively detach bonded devices, while not detaching devices that are not bonded to the target substrate. The transferred devices can be pressed against the target substrate during a second reflow process so that the top surfaces of the transferred devices can be coplanar. Wetting layers of different sizes can be employed to provide a trapezoidal vertical cross-sectional profile for reflowed solder material portions.

    Abstract: The present disclosure relates to a structure and method for embedding a non-volatile memory (NVM) in a HKMG (high-? metal gate) integrated circuit which includes a high-voltage (HV) HKMG transistor. NVM devices (e.g., flash memory) are operated at high voltages for its read and write operations and hence a HV device is necessary for integrated circuits involving non-volatile embedded memory and HKMG logic circuits. Forming a HV HKMG circuit along with the HKMG periphery circuit reduces the need for additional boundaries between the HV transistor and rest of the periphery circuit. This method further helps reduce divot issue and reduce cell size.

  • Publication number: 20170236835
    Abstract: An annular dielectric spacer can be formed at a level of a joint-level dielectric material layer between vertically neighboring pairs of alternating stacks of insulating layers and spacer material layers. After formation of a memory opening through multiple alternating stacks and formation of a memory film therein, an anisotropic etch can be performed to remove a horizontal bottom portion of the memory film. The annular dielectric spacer can protect underlying portions of the memory film during the anisotropic etch. In addition, a silicon nitride barrier may be employed to suppress hydrogen diffusion at an edge region of peripheral devices.

    Abstract: A semiconductor device with high design flexibility is provided. A first transistor and a second transistor having electrical characteristics different from those of the first transistor are provided over the same layer without significantly increasing the number of manufacturing steps. For example, semiconductor materials with different electron affinities are used for a semiconductor layer in which a channel of the first transistor is formed and a semiconductor layer in which a channel of the second transistor is formed. This allows the threshold voltages of the first transistor and the second transistor to differ from each other. Forming a gate electrode using a damascene process enables miniaturization and high density of the transistors. Furthermore, a highly-integrated semiconductor device is provided.
