Date of Visit: 16/03/2019

Venue: IIT-Bombay, Powai.

Timing: 9am to 12pm

Objectives:

  1. To see the nanofabrication setup.
  2. To understand the fabrication processes for MEMS devices.
  3. Practical explanation for theoretical concepts.
  4. For better understanding of processes.

Organized by:

Samita Bhandari (Asst. Professor- Department of Electronics Engineering).

Persons Involved:

  1. Abhijit Somnathe (HOD-Department of Electronics Engineering).
  2. Madhuri Kadam (Asst. Professor- Department of Electronics and Telecommunication Engineering).
  3. BE ETRX students .

Event Details:

A visit to IIT-Bombay Nanoelectronics department was organised by the faculty of Shree L. R. Tiwari College of Engineering for the students. IIT-Bombay has a set up for the nanofabrication processes for research purpose. And hence this visit was organised to have a brief idea about the theoretical concepts. Students were asked to report sharp at 9am at the main gate of IIT-Bombay. After completing the formalities, everyone reached the nanoelectronics building. There the students were divided into groups of 10. Each group was made to visit the various labs one by one accompanied by a research scholar there. Following topics were covered from the syllabus.

Deposition systems (CVD, ALD, PVD):

PVD Depositions:Silicon Nitride, Silicon Oxide, Silicon Oxy Nitride and Amorphous Silicon.
Types of substrates:2”,4”,8”, small pieces of wafers- Si, glass, Quartz.
Temperature:Room temperature to 380 degree Celsius.
Process gas used:SiH₄, N₂O, CF₄, Ar, He, H₂, N₂, NH.₃
Instrument Provider:Oxford Instruments.
Gases available:SiH₄, N₂O, CF₄, Ar, He,

Molecular Beam Epitaxy:

MBE takes place in high vacuum or ultra-high vacuum (10-8 Pa). The most important aspect of MBE is slow deposition rate (typically less than 1000 nm per hour), which allows the films to grow epitaxially. The slow deposition rates require proportionally better vacuum to achieve the same impurity levels as other deposition techniques.

Furnaces for oxidation, diffusion and annealing (2-inch, 4 inch):

During semiconductor device fabrication, thin film growth and deposition steps typically occur more number of times than any other process. These are often critical processes that require careful thickness and quality control. For example, during silicon transistor fabrication, growth of thin film SiO₂ is generally required immediately after the RCA clean process. This oxide can be grown on the Si wafer surface using different process that define its growth rate and quality. Whatever is the chosen process, maintaining the tight control of the process conditions and minimizing contamination on the wafer surface during the growth process is critical for final device performance. Hence, separate process-based oxide growth furnaces are needed for the same.

Etch tools (STS RIE, Etch Centura and Edge Isolation tool):

While a lithography process is used to write micrometre/nanometre-sized patterns on a resist layer, a different technique is needed to transfer those patterns from the resist onto the main layer on the semiconductor wafer. Wet etching and dry etching are the most commonly used processes to achieve this goal. Dr. etch usually refers to material removal or patterning using a chemically reactive plasma. When a lithographic patterned sample is introduced into this plasma, ionic species bombard and chemically react with the exposed areas, while the resist patterned areas are left protected. This method is anisotropic whereas wet etch is isotropic in nature. As a result, this method is preferable.

Lithography Tools:

IITBNF has multiple optical lithography tools with different dimension limits. They also have a laser writer system that is capable of producing mask plates with micrometre sized (patterns for use in optical lithography tools. The best resolution at IITBNF (< 20nm) is achieved through the state-of-the-art e-beam lithography tool. This tool can also be used for silicon dioxide and metal deposition using its electron beam induced deposition (EBID) feature. For both optical and e-beam tools, resist spinners dedicated to different types of resists are available with capabilities to process 2”, 4” and 8” wafers. All lithography tools housed in separate clean rooms with tight control over temperature and lighting conditions.

Plasma Immersion Ion Implanter:

As CMOS device gate length has shrunk to 45nm, the short channel effects (SCE) becomes very severe. To reduce SCE, one of the solutions is to make very shallow S/D junctions. For the same, implant energy is less than 2keV is required, where commercial Ion Beam Implanters have several issues like beam current instabilities at low voltages. PIII is very suitable for ion energy even at 200V operation. This system uses BF₃ and PH₃ gases for Boron (p type) and Phosphorous (n type) implants in Si wafers.

Event Outcomes:

Students have understood the concepts better and have come to know about the actual practical set up of nanofabrication processes. A visual idea was obtained by this visit about the Clean Room and Si wafers.

VENUE:Global Hospital, near Ramdev park Mira Road (E).


DATE: 24/08/2018


Students of TE ETRX SLRTCE  visited hospital for study and demonstration of some instruments like ECG machine, blood pressure measurement equipment and Defibrillator.

They observe various function and application of instruments and they demonstrated how it works practically

  • ECG Machine

    Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed over the skin. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle’s electrophysiological pattern of depolarizing and repolarizing during each heartbeat. It is very commonly performed to detect any cardiac problems. In ECG machine reading it shoes amount of  oxygen in body and various parameter etc.

  • Blood pressure measurement 

    The auscultatory method (from the Latin word for “listening”) uses a stethoscope and a sphygmomanometer. This comprises an inflatable (Riva-Rocci) cuff placed around the upper arm at roughly the same vertical height as the heart, attached to a mercury or aneroid manometer. The mercury manometer, considered the gold standard, measures the height of a column of mercury, giving an absolute result without need for calibration and, consequently, not subject to the errors and drift of calibration which affect other methods.useof mercury manometers is often required in clinical trials and for the clinical measurement of hypertension in high-risk patients, such as pregnant women. A cuff of the appropriate size is fitted smoothly and also snugly, then inflated manually by repeatedly squeezing a rubber bulb until the artery is completely occluded. It is important that the cuff size is correct: undersized cuffs record too high a pressure; oversized cuffs may yield too low a pressure. Usually three or four cuff sizes should be available to allow measurements in arms of different size.  Listening with the stethoscope to the brachial artery at the antecubital area of the elbow, the examiner slowly releases the pressure in the cuff

  • Defibrillator

    Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a countershock) to the heart. Although not fully understood, this would depolarize a large amount of the heart muscle, ending the dysrhythmia. Subsequently, the body’s natural pacemaker in the sinoatrial node of the heart is able to re-establish normal sinus rhythm. In contrast to defibrillation, synchronized electrical cardioversion is an electrical shock delivered in synchrony to the cardiac cycle. Although the person may still be critically ill, cardioversion normally aims to end poorly perfusing cardiac dysrhythmias, such as supraventricular tachycardiawe understood that Defibrillator is used only when there is emergency When the patients heart stops working, shock is given to trigger the heart otherwise pacemaker is used.
