Why Fabs Worry About Tool Parts

By Mark Lapedus

Achieving high yields with acceptable costs is becoming much more difficult as chipmakers migrate to next-generation 3D NAND and finFET devices—but not just because of rising complexity or lithography issues.

To fabricate an advanced logic chip, for example, a wafer moves from one piece of equipment to another in what amounts to 1,000 process steps or more in a fab. Any glitch with the equipment or a process step can cause defects, thereby impacting yield. The culprit may be a malfunction in seemingly insignificant parts or sub-systems in the equipment itself.

Senior C++ Computational Physics/Math Developer for Semiconductor Applications – Waltham, MA

At Coventor, a Lam Research company, we build innovative software products to solve semiconductor technology challenges.  Our 3D modeling software is revolutionizing the way that semiconductor chips are fabricated around the world.  Enabled by our core intellectual property – an accelerated 3D voxel modeling and visualization engine – our software is evolving fast as our business and customer base expands rapidly.

Coventor’s modeling team builds the core capabilities of SEMulator3D; the ability to model a wide variety of physical phenomena accurately and efficiently using a variety of numerical techniques.  As a key member of our modeling team you will implement new algorithms for modeling a wide range of semiconductor processes and phenomena such as plasma etching, chemical-mechanical polishing, and electrical behavior.  This is a hands-on software development position, requiring proficiency in C++ and expertise in and physical modeling. Your title, level of responsibility, creative freedom and salary will be commensurate with your education and experience.

Great engineering is Coventor’s heart and soul.  Our software is envisioned and created by world-class engineers in many disciplines: software engineering, numerical physics, statistics, electrical engineering, quality assurance and development operations.  Since our inception as an MIT spin-off, we’ve focused on agility by enabling individuals to take initiative and find innovative solutions to hard problems.  With our recent acquisition by Lam Research we have access to many more resources, and exciting opportunities for collaboration within the company. We are looking to hire engineers with broad skills who are ready to contribute in multiple ways, to enable our customers’ success.

Responsibilities:

  • Research, prototype and characterize methods for simulation of physical phenomena associated with fabrication and/or behavior of nanoscale semiconductor devices
  • Implement new modeling algorithms in C++, using and extending existing modeling infrastructure and APIs
  • Optimize algorithms for speed, including profiling and parallel implementation
  • Participate in general software engineering tasks, including verification, testing, bug fixing and maintenance of existing code

 

Required Qualifications (all of the following):

  • PhD in Engineering or Physical Science discipline, or Computer Science with a numerical simulation focus.
  • Direct experience implementing modeling/simulation algorithms in three dimensions, using methods such as finite-difference, finite-element, particle, atomistic, cellular automata etc.
  • Strong  C++ coding skills, including use of the standard template library
  • Strong math skills, including a thorough knowledge of calculus
  • Desire to collaborate, contribute to, and learn from a team

 

Desirable Qualifications (any of the following):

From Movies to Data Analysis – Coventor’s SEMulator 3D Pivots

If you’ve been paying attention to the various papers at various advanced semiconductor process conferences, there’s a name you’re seeing more and more: Coventor. We’ve looked at them several times before, in the context of both their SEMulator 3D tool and their MEMS+ tool – the former for development of new semiconductor processes and the latter for designing MEMS devices.

Today we’re focusing on the SEMulator 3D tool, whose 6.1 version was recently announced. We’re doing so because the tool has turned a corner on how it’s used. Before going there, let’s talk about where we’ve been first in order to set the stage.

Silicon Photonics: Solving Process Variation and Manufacturing Challenges

By: Sandy Wen, Principal Engineer

As silicon photonics manufacturing gains momentum with additional foundry and 300mm offerings, process variation issues are coming to light. Variability in silicon processing affects the waveguide shape and can result in deviation in effective indices, propagation loss, and coupling efficiency from the intended design. In this article, we will highlight process variation issues that can occur in silicon photonics manufacturing and discuss techniques to mitigate these effects.

Are Good Engineers Born or Bred?

By Steve Breit, V.P. Engineering

I’ve been doing a lot of interviewing as we grow our engineering team. I often say that hiring is the most important part of my job and also the hardest part. Like any sensible technology company, Coventor wants to hire the best engineers we can find. Good engineers love engineering. They love to build, to create, to innovate, to solve problems. Good engineers are methodical and persistent, but also bring engineering judgment and intuition that helps them arrive at solutions efficiently. Good engineers can’t help doing engineering – it’s who they are. Over the years, I’ve observed that good engineers are way more productive than mediocre engineers. The difference in productivity can be astounding, in excess of 2 or 3X for the best engineers. The trick, at least during the hiring process, is to discern which candidates are the good engineers. You can’t just look at academic degrees, skills claimed, or work experience to tell the difference. read more…
