Resistance Switching Behavior of Oxide Devices for Memory
Synopsis
The semiconductor industry has long sought a high-density and high-speed non-volatile memory (NVM). Recently, resistance random access memory (ReRAM) of oxide devices as a new candidate of NVM has emerged. Because a design guide for ReRAM based on a driving mechanism has not been clear, researches on resistance switching (RS) would be important. Pulse Laser Deposition (PLD) is a popular oxide thin film deposition technique. Based on oxide junctions with current-voltage and other measurements, the project will try to understanding RS behavior in oxide devices and searching suitable oxide film deposition technique acceptable for silicon process Meanwhile, the project will provide better understanding of the knowledge of novel oxide electronics devices including it electric characteristics and physical properties. The use of NanoCore facilities would provide an opportunity for cutting edge oxide thin film research and provide a platform for generating oxide material databases for researchers and students in the lab.
In a network, there are scenarios which we will need to process certain data and need to request data from other sources. This takes time to process. It is crucial to complete the task if we can minimize the time taken in processing data collection and verifying the availability of the network sources connected. The aim of this project is to develop a GUI software that will choose the most appropriate algorithm to schedule the current load topology process so as to minimize processing time in a network and optimize the duration in real-time processing.
Good recipe is the most important & fundamental base of YDD. The above project involves learning in depth one of the ydd tool namely KLA-Tencor (KLA-Tencor tools are specialized in yield management & process control solutions.) & exploring its recipe parameters in order to create a database to have comparable recipes across all the tools of the fab. The project also includes having the in depth knowledge of the signals to adjust & tune the recipe parameters using the signal to noise ratio, histogram & graph of the Light Level Box which is the most important parameter of the recipe set-up & also understanding the theory behind working of the tools.
Recipe control will involve creating database for all the recipes (Devices & their layers) across both the fabs, comparing & fine tuning the recipe parameters across all the tools so as to make them comparable & consistent in order to catch maximum number of true defects & thus, getting rid of the noise.
Recipe Management will involve monitoring the database created for any recipe drift, addition & fine tuning of new or existing recipes in other tools, solving line issues regarding recipe’s & suggesting methods to improve the baseline of the current line.
Advantages & benefits of the project when accomplished:
1.Systematic compilation of recipe’s & their status.
2.Database creation which projects an overview of all the recipe available in the tool, its baseline, recipe details, modification details, reason, tests available & their reason of creation ( more or less sensitive, etc.).
3.Assist specialists & AE’s in selecting the tools for scan immediately when the lot arrives instead of checking the recipe availability in each tool thus avoid the time consumption.
4.Future projection, analysis & improvements of recipes.
5.Reduce unnecessary workload of specialists & AE’s by reducing the partial scans of wafers due to ZPLL errors, etc., rescanning in different tests or other tools due to hdd of noise, which in turn will improve the queue time, machine time by scanning more number of wafers & thus increasing the sampling to detect issues as fast as possible, react immediately & shut down the tool thus reducing the exposure.
Interfacing and Real-Time Control of an Omni-directional Mobile Robot
Synopsis
The objective is to develop a PC-based real-time controller for an Omni-directional mobile robot. This robot can independently translate and rotate along a horizontal plane with 3 independent degrees of freedom (translating along x and y directions and rotation around the z axis direction).The project involves hardware interfacing to allow the real-time control application on the computer. The application will have the capability of interpreting commands from user to perform high intelligent tasks. Sensors will be installed at the robot in order to activate self-control logic. The student will learn communication methods being used between computer and the sensors and actuators of the mobile robot. Furthermore, the student will gain experience in developing real-time control algorithms running on a PC.
Investigation of energy band-gap in grapheme nanoribbons.
Synopsis
The objective of this project is to investigate the energy band-gap engineering in graphene. When graphene is patterned into a narrow ribbon, the carriers are confined to a quasi-one-dimensional (1D) system, where we expect the opening of an energy gap. The integration of Helium Ion microscope and Nano Pattern Generation System (NPGS) provides a directly patterning on graphene with a finest feature less than 10nm. The low temperature electrical transports will be carried out to measure the band-gap of graphene nanoribbons.
