Tips on getting a VLSI internship with fab experience?

Hi All,

I am currently pursuing my master's in ECE and I would like your advice on how to increase my chances in finding a summer internship or co-op for next Fall.

I studied ChemE and have 5 years of industry experience in fab (etch in FeOL), currently looking to transition my career to VLSI/design in general with the graduate degree in ECE, but I recognize that I have very limited relevant experience in order to secure an internship in this field.

I will be taking solid state devices course in the spring, and then MOS VLSI design course next fall. Prior to these, I'm planning to take a coursera course to get familiarized with HDL. I have very little confidence at this point since I haven't had any experience in VLSI.

A few questions I have:

- Is there any way that my fab experience can be relevant to VLSI?

- Anything else I can self-learn to build a strong resume?

- What qualifications do interns in VLSI usually hold?

- Other career suggestions if you think my plan is absurd?

Thank you!

Urgent: need to make a critical decision by 11:00 AM today

I'm an undergraduate just completed my 7th semester from an average IIIT, today I got an offer of 5 LPA from a company for the hardware role, it has good work culture and growth environment and its work location is Chennai which is far from my native.

My current cpga is almost 9 out of 10 and I have decent knowledge also interest to work in hardware role but I'm a fresher and don't have any experience in hardware or any other role.

In the dileme to take it or reject the offer.

My reason for dilema: The number of companies coming to my college for the drive on hardware are very few. So I'm not sure how many will come in the last semester that are of hardware role (which I'm interested in) and my current state of mind is that 5 LPA is not good enough considering the amount of effort and time I put in so I'm almost at the edge of thought to reject the offer.

Is 5LPA really a decent offer for hardware? Help me avoid making a bad decision.

Thankyou.

How to improve Resume for Hardware/Embedded Internships?

Anonymized Resume

For context, I am targeting digital hardware or embedded internships. I am also applying for ECE technical sales internships which sound really fun, but such openings are rare to find.

For more context, I am USA-based, and all of my experience has been unpaid or for academic credit except for my undergraduate teaching assistant role. Also, none of these roles have been completely full-time, if it matters.

I’ve had my resume reviewed by TI employers at a TI-sponsored event at my school, and they said it looked good, but I‘ve had no luck getting an interview from them or any company, except 1, which I’m still waiting to hear back from.

I’ve applied to many many internships, so what can I do to improve my resume?

hi

I am currently pursuing ECE 2nd year in Bangalore. SO, I am basically a guy who doesn't like coding and I am interested in vlsi (chip) like ASIC . But Now am not sure where to start in this journey cause i want to pursue a career which requires minimal coding and has a demand in every semiconductor company like synopsys,analog devices,broadcom etc,( I want to learn some proper skills which can be used for various careers in vlsi so that hands on project and extra skills will land a job for a fresher one like me , Any suggestions would be really helpful and appreciated

LEAP program Boston University

Does anyone here have enough knowledge about the LEAP program at Boston University for non-engineering students seeking to enter engineering, in the context of being an international student and seeking for funding opportunities.

Thanks

Stochastic applications

I'm a 3rd year student currently studying ECE. I found a book "Stochastic Dynamics, filtering and Optimization by Cambridge press" and brought it home. Now I'm questioning if it's worth studying since I will have limited time for each semester and there are subjects like communication system and others.

What is a 3 input priority encoder.

Basically I have my digital paper tomorrow and was going through previous year questions of my college

One of the questions is to design a 3 input priority encoder using a suitable decoder.

But what is a 3 input priority or for that matter any encoder.

Isn't encoders of the 2^n:n

Then how can we have the input side having 3 bits.

I would be grateful if you can shed light on this.

Starter Pistol transducer (?) to close contact on Timer remotely

Track Coach here.... My school still uses an Ultrak L10 to time meets and I am looking for a way to diy a solution to simplifying the start of a race. Currently we just have the "head timer" watch for the smoke of the starting pistol to operate a plunger that closes a contact to start the timer. I would love to put together a system that has 2 parts, transmitter (Starter pistol end) and receiver (Timer end). We have a minimal budget so I would be purchasing and building everything myself.

  • Starter is wearing the Transmitter (clip on to belt, maybe wristband?)
  • Receiver end plugged into Timer
    • NO Contact
  • Starter fires pistol and Transmitter picks up signal
    • Max distance would be 500'
    • Line of sight, no trees or other obstacles
  • Receiver picks up signal and closes contact
    • Momentary, not maintained
  • System is ready after each shot

Microsoft: No available role after interview

Has anyone had any experience with this? I interviewed for an EE internship (received positive feedback from interviewers), and the recruiter followed up:

“We do not have an existing role for you at this time. However, you will remain eligible for placement on a new team if headcount becomes available within the next 6 months.”

Is it still likely to get an offer? What can I do to improve my chances of getting an offer?

How hard is an online master's in ECE?

I’ve been admitted to an online Master’s in ECE and need to finish in 3 years (company-sponsored). I’m planning to take 6 credits per semester for the first 2 years, then 3 credits in the final year.

I’ll be working full-time while pursuing this degree, so I’m concerned about the difficulty level. How challenging are the courses? Will I struggle with assignments or time management? For context, I have 18 years of experience in semiconductor design, focusing on analog and VLSI.

Post-Silicon Validation Interview - Help!

Hello,

I just received an interview invite for new grad Post-Silicon Validation at a large company, and I really don’t want to mess it up. I’m graduating in 2025, fyi.

What topics do you think would be asked on the interview?

Thank you so much!

Edit: this is most likely post-silicon IC chip validation, either in Digital or high-speed IO validation.

Sine Generator Signal to Digital Signal

For context, the assignment is the following:

Design a digital frequency meter whose test signal is a variable frequency sinusoidal input with a constant DC level of 2.5 Volts, the amplitude of the wave must be 2.5 Volts. The frequency meter reading must be displayed on a graphing screen. The reading range must be from 0 to 100 hertz with two decimal places of precision (example: 100.00 hertz). For readings greater than 100 hertz, a message must be displayed indicating that the frequency meter reading range is exceeded. Leading zeros must not be displayed in the reading. Use Proteus

The thing is, I have to use a PIC 18F4550 and insert the sine signal (I decided to use the SINE GENERATOR component of the simulator), but it needs to first be converted to a digital signal to be properly read.

How do I even do that??? I haven’t found a single guide to do this.

RING OSCILLATOR

Hi everyone, I’m currently working on a project where I have to design a ring oscillator to generate a variable clock signal, and I’m feeling a bit stuck. The oscillator needs to be made up of delay cells that are looped back on themselves, using “NOT” gates, with an architecture based on MOSFET transistors. The goal is for the circuit to produce a maximum frequency above 100 kHz, with the ability to adjust the frequency for creating a variable clock signal. It will be powered by a 9V DC source, and I’ll be using MOSFETs, resistors, and capacitors to build it. On top of that, I need to simulate the circuit and ensure it functions correctly during the transient startup phase. I’m looking for advice on how to choose the right components, make the frequency adjustable, and handle the simulation process. If you’ve worked on something similar or have any resources, tips, or insights, I’d be really grateful for your help. Thanks so much!

What path should i choose

I am a first sem student from Nepal, I chose ECE as my undergrad major here as I couldn't afford abroad fees; I am fixed that I would do master's immediately after my bachelor's; I come from a relatively poor family so I can't afford much external equipment/guidance and all I have learned is from the laptop my parents just got me || so I want to ask for your advice about what niche skill/field I should join that could pay extremely well / is easy while processing for visas in another country;

thank you for taking your time with this, hope you have a great day

Online Study Materials for Microprocessors and Microcontrollers and Analog devices and Circuits

I am currently in 2nd Year. I had Signals and Systems in my last semester. I learnt that course from Dr. Alan Opennheim's lectures in MIT OpenCourseWare and his book. It was an amazing learning Experience. This semester, I have Microprocessors and Microcontrollers and Analog Devices and Circuits. I was hoping if anyone could recommend me where and how to start. Please give any relevant links to online courses, or books or relevant course materials. It would be very helpful.

BSBME to CE Masters career advice?

Hi everyone. I have a BS in biomedical engineering. I really floated through my BS and took away very limited technical skills and graduated with a 2.5. I’ve been working at a decently large biotech now for 4 years and they make a wide range of blood gas / advanced cell counting analyzers. I have had what’s felt like a mini “internship” where I was thrown into the design of hardware and how software controls basically everything.

I want to go back to school for CE to get more technical knowledge into the design of these units and how software controls and impacts the devices. Has anyone had experience getting their masters in CE? Or bridging that gap of not being very technical and then picking up a masters to get more practical knowledge?

Thank you!
