Part 2: Business Engineers : 7 Things to Consider, Before Investing in a Personal Robot

2019-07-14T11:52:33-07:00

So you’ve made the decision, robotics process automation (RPA) is for your business. You’ve winnowed down a list of suitable vendors and are ready to start some serious shopping. Great. But before you plunge right in, there are some final things to consider.  The following is a list of questions for would-be buyers to which they should give serious thought to before moving forward. They range from the existential — what role will your employees play as RPA expands within your organization? To the practical, such as training time frames. 1. RPA [...]

2019-07-14T11:53:21-07:00

Figure 1.  Solar Powered Cars in the Future Although a solar power car may not be commercially viable right now, there are ways that solar power can be added to existing designs to make vehicles more efficient. Material Scientist examine the pros and cons of this technology, it can continue to move forward in development to help save on fossil fuels, and the electric grid and pollutions. Solar-powered vehicles (Solar Cells ) have zero emission level, as they don’t utilize non-renewable resources and burn fuel. The electric motors generate electricity (See Figure 1.) that [...]

Semiconductor Record Fab Spending 2018

2019-07-14T11:53:30-07:00

Good News for Materials Scientists - Semiconductor Record Spending Fab spending reports show unprecedented high semiconductor equipment sales are being driven by a handful of well-known companies, and also by several new Chinese companies entering the semiconductor marketplace. An increase in overall fab spending (greenfield construction and equipment together) of 54 percent year-over-year (YoY) in China is expected.  Total spending in China rose from $3.5 billion in 2016, to $5.4 billion in 2017, and then is anticipated to be $8.6 billion in 2018, another 60 percent year-over-year (YoY). The demand for [...]

NAND Flash – 11 Myths Still Floating Around

2019-07-14T11:53:32-07:00

Think You Know NAND Flash?  NAND flash has become the de facto memory standard in the years since Toshiba first introduced it almost three decades ago. However, many misconceptions remain to this day about its use. A wide variety of NAND flash-memory products are available, all with significantly different features and capabilities.    All NAND flash has the same interface. NAND flash, introduced by Toshiba more than 20 years ago, is available in both the asynchronous and toggle-mode interfaces. The original asynchronous interface is found mostly in lower-density devices [...]

Semiconductor Worldwide: Samsung Takes Over

2019-07-14T11:53:35-07:00

Samsung topples Intel as top dog semiconductor market share  Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category.  DRAM prices rose 44 per cent from 2016 [...]

Wind Load CFD Modeling for Rooftop Elements Compared to ASCE 7

2018-02-20T11:28:46-07:00

  Wind Load Comparison between CFD and ASCE 7 for Rooftop shapes Welcome back to our blog series on the phenomenon called Wind Load CFD Modeling and how it affects civil and mechanical engineers.  Wind Load is the force that blowing wind exerts on any device or structure that extends above ground level.  After an initial introduction to the factors that affect wind load on an object, I compared three different sets of wind load calculation methods using three simple objects, hypothetically placed on a 100-foot-tall building.  Starting with generic drag equation [...]

Figure 1: Unpowered Sony Ericsson S500i LCD screen at 200x magnification In our last blog post, I wrote about some of the physics and materials science principles that go into the design and manufacture of liquid-crystal display (LCD) screens.  The eponymous liquid crystals (LCs) in such a display have to be quite small in order to create a seamless image; as I mentioned in the last entry, the subpixels (the red, green and blue elements comprising a pixel, visible in Figure 1) can be smaller than a red blood [...]

Semiconductor Safety: Pyrophoric Gases

Fig. 1 Tall Fire from Chemical We have written about pyrophoric materials in a number of Glew Engineering’s previous blogs on safety in semiconductor fabrication, but have yet to cover how to define it or its danger.  At its simplest, a pyrophoric substance is any substance that spontaneously ignites in room temperature air.  As one might imagine, spontaneous combustion on contact with the regular atmosphere we live in can be quite dangerous. Last year, Glew Engineering assisted a research lab in designing a safe gas distribution system for their plasma-enhanced chemical vapor deposition chamber. [...]

High-purity Gas Panels Part 11: Mass Flow Controllers

2018-03-22T16:08:42-07:00

Thermal Mass Flow Controllers A mass flow controller (MFC) for each gas line in a semiconductor tool’s gas panel measures and regulates the mass flow of the gas in order to set the gas entering the process chamber to the values in the process recipe.  While pressure regulation and temperature control are needed for sensitive chemical vapor deposition (CVD), plasma etching, or thin film processes, gas flow control can be just as important. Semiconductor process recipes involve precise ratios of gas phase chemical to assure the correct stoichiomtery and reaction rates. [...]
