    Abstract: In a method of fabricating a Fin FET, first and second fin structures are formed. The first and second fin structures protrude from an isolation insulating layer. A gate structure is formed over the first and second fin structures, each of which has source/drain regions, having a first width, outside of the gate structure. Portions of sidewalls of the source/drain regions are removed to form trimmed source/drain regions, each of which has a second width smaller than the first width. A strain material is formed over the trimmed source/drain regions such that the strain material formed on the first fin structure is separated from that on the second fin structure. An interlayer dielectric layer is formed over the gate structure and the source/drain regions with the strain material. A contact layer is formed on the strain material such that the contact layer wraps around the strain material.

  • Publication number: 20130260056
    Abstract: Apparatuses and processes for maskless deposition of electronic and biological materials. The process is capable of direct deposition of features with linewidths varying from the micron range up to a fraction of a millimeter, and may be used to deposit features on substrates with damage thresholds near 100° C. Deposition and subsequent processing may be carried out under ambient conditions, eliminating the need for a vacuum atmosphere. The process may also be performed in an inert gas environment. Deposition of and subsequent laser post processing produces linewidths as low as 1 micron, with sub-micron edge definition. The apparatus nozzle has a large working distance—the orifice to substrate distance may be several millimeters—and direct write onto non-planar surfaces is possible.

  • Patent number: 8110247
    Abstract: A method of depositing various materials onto heat-sensitive targets, particularly oxygen-sensitive materials. Heat-sensitive targets are generally defined as targets that have thermal damage thresholds that are lower than the temperature required to process a deposited material. The invention uses precursor solutions and/or particle or colloidal suspensions, along with optional pre-deposition treatment and/or post-deposition treatment to lower the laser power required to drive the deposit to its final state. The present invention uses Maskless Mesoscale Material Deposition (M3D™) to perform direct deposition of material onto the target in a precise, highly localized fashion. Features with linewidths as small as 4 microns may be deposited, with little or no material waste. A laser is preferably used to heat the material to process it to obtain the desired state, for example by chemical decomposition, sintering, polymerization, and the like.
