Ruhai Tian is a Staff Engineer working for Seagate Technology. As a world widely known public company (STX), Seagate is one of the largest manufactures and providers of digital storage hardware (SSD, HHD, Cloud) and solutions. Seagate Technology designs, manufactures, markets, and sells hard disk drives for enterprise storage, client compute, and client non-compute market applications worldwide. The company’s products are used in enterprise servers, mainframes, and workstations; desktop and notebook computers; and digital video recorders, gaming consoles, personal data backup systems, portable external storage systems, and digital media systems. It also provides data storage services, including online backup, data protection, and recovery solutions for small and medium-sized businesses. Seagate Technology was founded in 1979 and is headquartered in Dublin, Ireland.

Mr. Tian's specialties at Seagate are:
 * 1) Cleaning & Contamination Engineering
 * 2) Material Engineering
 * 3) Yield Improvement
 * 4) Process Integration

From January 2013-July 2013, Mr. Tian was working for Sematech's Nanodefect center. SEMATECH’s Nanodefect Center aims to build industry participation in detecting, modeling, characterizing, and providing solutions for defect issues as geometries shrink below the 10 nm node. The center repreents SEMATECH's world leading suite of metrology and analysis capabilities to investigate the generation, propagation, removal, and impact of defects generated by equipment, equipment components, and materials used in advanced semiconductor processes such as lithography, etch, CMP, deposition, and cleaning.

Mr. Tian'swork was to coordinate his work with the work of his colleagues to complete group projects. The focus is to study the formation, transportation and deduction of <10nm defects.

Mr. Tian's specialties at Sematech Nanodefect Center are:
 * 1) Particle fabrication, dispersion in liquid chemicals
 * 2) Particle detection, classification, counting and deposition on different surfaces
 * 3) Particle surface interaction and surface science
 * 4) Defect inspection on mask and wafer surface
 * 5) Trace element detection and water quality improvement
 * 6) Native particle analysis
 * 7) Chemical purification

From January 2012-January 2013, Mr. Tian was working for Lithography Division at SEMATECH

Extreme ultraviolet lithography (EUVL) is a next-generation lithography technology using an extreme ultraviolet (EUV) wavelength, currently expected to be 13.5 nm which allows fabrication of extremely small devices. (http://en.wikipedia.org/wiki/Extreme_ultraviolet_lithography). SEMATECH plays a unique role in supporting mask infrastructure development, spearheaded by its EUV Mask Blank Development Center, the world’s sole research facility devoted to improving EUV mask blanks.

By employing comprehensive edge cutting technologies, his work was mainly focused on EUV mask cleaning to address both the technical and fundamental issues which have been involved in since dozens years ago. The goal was to accelerate the EUV technology to the manufacture.

His Specialties at Specialties at Lithography Division at SEMATECH are:
 * 1) Surface cleaning with chemical formulations (organic & inorganic, liquid and gas)
 * 2) Surface cleaning with irradiation (UV&Laser)
 * 3) Surface cleaning with megasonic devices
 * 4) Fundamental surface science of a variety of different capping layer materials
 * 5) New technology development for EUV blank cleaning

From 2008 to 2012, Mr. Tian worked at Erik Jonsson School of Engineering, The University of Texas at Dallas (UTD). By collaborating with Simmons Comprehensive Center at University of Texas, Southwest Medical Center (UTSW) and Texas Instrument, He worked on development of reliable silicon nanowire field effect transistor biosensors and also partly involved in drug delivery, micelle and tumor research. His research work at UTD is leading this research filed and the group has received more than 2 million dollars grant from governmental institute (National Institutes of Health (NIH) and National Science Foundation (NSF)), medical institutes as well as semiconductor industry (Texas Instrument). Daigtronix, a start-up company is also the fruit from these research efforts.

His work at UTD was focused on the state-of-art silicon nanowire field effect transistor technology and associated applications as ultra-sensitive biosensors used for such as early cancer detection, diabetes diagnosis and many other diseases. The versatile applications of this novel biosensor technology are of extreme importance to the health care, human society, country security, and global economy. During his employment at UTD, he has made tremendous contributions to the field of silicon nanowire field effect transistor biosensors, including chip design, device fabrication, device surface functionalization, etc. These innovative research results have greatly helped in understanding of the device physics, surface science of silicon and silicon oxide, and mass transportation in fluidic system.

Mr. Tian's Specialties at UTD are:
 * 1) Modification of Si and SiO2 surfaces by self-assembly
 * 2) Bio molecule immobilization on functionalized surfaces
 * 3) MiltiNanowire FETs design and fabrication
 * 4) MOS device physics and parametric analysis
 * 5) Microfluidic system
 * 6) Biosample separation and analysis
 * 7) Micelle fabrication and characterization
