Process variation significantly affects product quality and yield in scaled CMOS technologies. Managing process variation is a critical challenge in high volume high mix semiconductor manufacturing environment. This work describes different aspects of overall product yield improvement by reducing CMOS spacer thickness variation.

The technology available today for interacting with a virtual environment involves wired or wireless hand controls with limited buttons or a large setup involving a camera and/or a sensor to capture movements. The cost of such a setup is such that it makes it inaccessible to most. The project aims at providing a cost effective VR solution which can produce the same effect with precision and flexibility, which is accessible to all. The proposed idea is to provide a hardware device that provides the user with an immersive VR experience and uses hand gestures captured via a camera placed on the device to control and interact with the VR environment. As an application of the project, an interactive workspace environment would be simulated, using a single hardware component that provides the user the viewing interface as well as can be controlled by simple hand gestures eliminating the need for additional hand-held devices controls. The project will also delve into the field of supervised learning to make possible the implementation of gesture recognition.
