20140151760 | DOPED FLOWABLE PRE-METAL DIELECTRIC - A method of filling gaps between gates with doped flowable pre-metal dielectric (PMD) and the resulting device are disclosed. Embodiments include forming at least two dummy gates on a substrate, each dummy gate being surrounded by spacers; filling a gap between adjacent spacers of the at least two dummy gates with a flowable PMD; implanting a dopant in the flowable PMD; and annealing the flowable PMD. Doping the flowable PMD prevents erosion of the PMD, thereby providing a voidless gap-fill. | 06-05-2014 |
20140175562 | SPACER DIVOT SEALING METHOD AND SEMICONDUCTOR DEVICE INCORPORATING SAME - A semiconductor structure in fabrication includes a NFET and a PFET. Spacers adjacent gate structures of the NFET and PFET have undesired divots that can lead to substrate damage from chemicals used in a subsequent etch. The fabrication also leaves hard masks over the gate structures with non-uniform height. The divots are filled with material resistant to the chemicals used in the etch. Excess filler is removed, and uniform height is restored. Further fabrication may then proceed. | 06-26-2014 |
20140193957 | REDUCING GATE HEIGHT VARIANCE DURING SEMICONDUCTOR DEVICE FORMATION - In general, aspects of the present invention relate to approaches for forming a semiconductor device such as a FET with reduced gate stack height variance. Specifically, when a gate stack height variance is detected/identified between a set of gate stacks, a hard mask layer and sets of spacers are removed from the uneven gate stacks leaving behind (among other things) a set of dummy gates. A liner layer and an inter-layer dielectric are formed over the set of dummy gates. The liner layer is then removed from a top surface (or at least a portion thereof) of the set of dummy gates, and the set of dummy gates are then removed. The result is a set of gate regions having less height variance/disparity. | 07-10-2014 |
20140339612 | USING SACRIFICIAL OXIDE LAYER FOR GATE LENGTH TUNING AND RESULTING DEVICE - Methods for controlling the length of a replacement metal gate to a designed target gate length and the resulting device are disclosed.

20150041909 | COMPLETING MIDDLE OF LINE INTEGRATION ALLOWING FOR SELF-ALIGNED CONTACTS - In general, aspects of the present invention relate to approaches for forming a semiconductor device such as a FET having complete middle of line integration. Specifically, a hard mask layer and set of spacers are removed from the gate stacks leaving behind (among other things) a set of dummy gates. A liner layer is formed over the set of dummy gates and over a source-drain region adjacent to the set of dummy gates. The liner layer is then removed from a top surface (or at least a portion thereof) of the set of dummy gates and the source-drain region. An inter-layer dielectric (ILD) is then deposited over the set of dummy gates and over the source-drain region, and the set of dummy gates are then removed. The result is an environment in which a self-aligned contact to the source-drain region can be deposited. | 02-12-2015 |

20120092979 | METHOD OF PARALLEL BIT-WISE HOLOGRAPHIC DATA STORAGE USING A PARALLEL LIGHT SOURCE - The present techniques provide techniques for outputting counter-propagating parallel light waves to pre-record a holographic data disk. The parallel light waves are transmitted through a holographic system via a fiber optic bundle including a plurality of polarization-maintaining (PM) optical fibers. Each of the PM optical fibers in the fiber optic bundle may have one or more of a different wavelength, a different coherence length, and a different polarization orientation to reduce crosstalk in the disk. Furthermore, the fiber optic bundle array is rotated to produce interference spots indicative of micro-holograms according to the data track pitch of the holographic disk over which the fiber optic bundle is outputting the light waves. | 04-19-2012 |
20120092980 | REPLICATION AND FORMATTING METHOD AND SYSTEM FOR BIT-WISE HOLOGRAPHIC STORAGE - The present techniques provide methods and systems for recording micro-holograms on a holographic disk using a plurality of counter-propagating light beams in parallel. The parallel counter-propagating light beams overlap to form interference patterns on a data layer and over multiple data tracks in the holographic disk. Rotating the disk enables the parallel recording of micro-holograms over multiple data tracks, thus reducing recording time. Further, the illumination pattern may include illuminated spots and non-illuminated regions, such that each illumination spot may cover a relatively small fraction of the data layer plane, possibly controlling the depth spread of the recorded micro-hologram. In some embodiments, data in the parallel signal beams may be retrieved from a master holographic disk or may be modulated into the parallel signal beams. | 04-19-2012 |
20120127843 | SERVOING SYSTEM FOR MASTER WITH PARALLEL TRACKS IN A HOLOGRAPHIC REPLICATION SYSTEM - Techniques are provided for controlling the reading of optical data from a master disk in a holographic replication system. Imperfections in the master disk or movement of the disk during a recording process may cause source beams to deviate from target data tracks. In some embodiments, a detector system is used to determine the focus and alignment of the source beams on the master disk, as well as the tilt and rotation of the disk with respect to the holographic replication system. The detector system may detect deviations in the intensity distribution of the reflections of the source beams and generate an error signal corresponding to focusing, tracking, tilt, and/or rotational errors. Servo-mechanical devices may actuate optical components to compensate for such errors. | 05-24-2012 |
