Abstract: A system and methods of forming a dielectric material within a trench are described herein. In an embodiment of the method, the method includes introducing a first precursor into a trench of a dielectric layer, such that portions of the first precursor react with the dielectric layer and attach on sidewalls of the trench. The method further includes partially etching portions of the first precursor on the sidewalls of the trench to expose upper portions of the sidewalls of the trench. The method further includes introducing a second precursor into the trench, such that portions of the second precursor react with the remaining portions of the first precursor to form the dielectric material at the bottom of the trench.

Abstract: Embodiments of the present disclosure provide semiconductor device structures and methods of forming the same. The structure includes a first source/drain region disposed in a PFET region and a second source/drain region disposed in an NFET region. The second source/drain region comprises a dipole region. The structure further includes a first silicide layer disposed on and in contact with the first source/drain region, a second silicide layer disposed on and in contact with the first silicide layer, and a third silicide layer disposed on and in contact with the dipole region of the second source/drain region. The first, second, and third silicide layers include different materials. The structure further includes a first conductive feature disposed over the first source/drain region, a second conductive feature disposed over the second source/drain region, and an interconnect structure disposed on the first and second conductive features.

Abstract: A method of using PET imaging includes using PET images obtained using a radiotracer for the determination of the progressive course of regional brain PET activities for a progressive neurodegenerative disease (e.g., MCI, AD, and CTE). The method may be used for the automatic staging of neurodegenerative disease for a particular patient/subject based on regional intensity and spatial patterns of the brain signals measured by PET imaging. The method may also be used to diagnose or classify the disease of a patient among multiple possibilities based on PET imaging profiles (e.g., for separating or distinguishing CTE from AD).

Abstract: An improved method for computed tomographic scanning is disclosed. A beam of electromagnetic radiation subtending an angle .phi. is alternately translated and rotated past a patient. The intensity of the beam is detected by an array after the radiation passes the patient and a reconstructed image created from the detected intensities. Each rotation of the array is through an angle less than the angle .phi. subtended by the array producing redundant intensity readings for similarly oriented beam paths through the patient. This redundant intensity data is modified according to a scheme which tends to reduce motion and misalignment artifacts within the patient.
