Researchers have singled out a bacterial enzyme behind an imbalance in the gut microbiome linked to Crohn’s disease. The new study suggests that wiping out a significant portion of the bacteria in the gut microbiome, and then re-introducing a certain type of ‘good’ bacteria that lacks this enzyme, known as urease, may be an effective approach to better treat these diseases.
Type 1 diabetes has been successfully reveresed in a mouse model by infusing blood stem cells pre-treated to produce more of a protein called PD-L1, which is deficient in mice (and people) with type 1 diabetes. The cells curbed the autoimmune reaction in cells from both mice and humans and reversed hyperglycemia in diabetic mice.

Seoul Semiconductor introduces an Acrich-based compact LED lriver with 5X the power density of conventional drivers
Seoul Semiconductor has developed an ultra-compact LED driver series with a power density 5X higher than conventional LED drivers. Based on Seoul Semiconductor’s patented Acrich technology, the MicroDriver Series delivers more than 24W of output power with a power density of 20W/cubic inch cubic inch, compared to existing drivers at 3-5W/cubic inch. Measuring just 1.5″ x 1.1″ x 0.8″ (38mm x 28mm x 20.5mm), the MicroDriver is 80% smaller than conventional LED drivers, giving lighting designers the ability to develop ultra-thin and novel luminaires with flicker-free operation.
“The new MicroDriver Series LED drivers will have a significant impact on external converters, enabling lighting design engineers to dramatically reduce the size, weight and volume of their luminaires,” explained Keith Hopwood, executive vice-president at Seoul Semiconductor. “This breakthrough in size reduction for the MicroDriver Series is the result of the company’s continuing investment in Acrich high voltage LED technology, delivering benefits for customers in smaller size, increased efficiency and lower costs.”
The MicroDriver Series LED drivers are ideal for lighting designs such as wall sconces, vanity lights, downlights, and flush-mounted lighting fixture applications. The MicroDriver Series’ smaller size facilitates the conversion of these applications to LED light sources, which was not previously possible due to bulky conventional LED drivers, making halogen lamp replacement possible without the need for a large volume recess for the driver, or a reduction in light output.
The MicroDriver Series LED drivers are ideal for luminaire designs up to 2,400 lumens, and their compact size enables integration of the lighting control circuitry with the external converter. This gives lighting designers the capability to mount more light sources on the board or reduce the total size of the fixture and mounting plate.
The resulting decrease in the LED drivers’ physical size has significant business implications for the lighting industry, giving lighting designers the ability to shrink the size of light fixtures by as much as 20%, which reduces shipping and storage costs. Because conventional LED drivers are both heavy and bulky, they are typically shipped via sea freight from manufacturers in Asia to European and North American fixture companies, with transit times up to six weeks. The MicroDriver Series LED drivers are small and lightweight enough to make airfreight practical and economical, reducing lead time and streamlining the overall supply chain.
The MicroDriver Series is rated to IP66, and is available in 10 models, rated for 8 – 24W in 120V or 230V versions, for LED assemblies from 900-2400 lumens. The drivers are CE recognized, provide flicker-free operation for phase-cut dimmers, and are compliant to California Title 24, enabling lighting designers to meet the most challenging design requirements, including low flicker, high power factor, Class B EMI and 2.5kV surge.
IC Insights has revised its outlook for semiconductor industry capital spending and will present its new findings in the November Update to The McClean Report 2017, which will be released at the end of this month. IC Insights’ latest forecast now shows semiconductor industry capital spending climbing 35% this year to $90.8 billion.
After spending $11.3 billion in semiconductor capex last year, Samsung announced that its 2017 outlays for the semiconductor group are expected to more than double to $26 billion. Bill McClean, president of IC Insights stated, “In my 37 years of tracking the semiconductor industry, I have never seen such an aggressive ramp of semiconductor capital expenditures. The sheer magnitude of Samsung’s spending this year is unprecedented in the history of the semiconductor industry!”
Figure 1 shows Samsung’s capital spending outlays for its semiconductor group since 2010, the first year the company spent more than $10 billion in capex for the semiconductor segment. After spending $11.3 billion in 2016, the jump in capex expected for this year is simply amazing.
To illustrate how forceful its spending plans are, IC Insights anticipates that Samsung’s semiconductor capex of $8.6 billion in 4Q17 will represent 33% of the $26.2 billion in total semiconductor industry capital spending for this quarter. Meanwhile, the company is expected to account for about 16% of worldwide semiconductor sales in 4Q17.
IC Insights estimates that Samsung’s $26 billion in semiconductor outlays this year will be segmented as follows:
3D NAND flash: $14 billion (including an enormous ramp in capacity at its Pyeongtaek fab)
DRAM: $7 billion (for process migration and additional capacity to make up for capacity loss due to migration)
Foundry/Other: $5 billion (for ramping up 10nm process capacity)
IC Insights believes that Samsung’s massive spending outlays this year will have repercussions far into the future. One of the effects likely to occur is a period of overcapacity in the 3D NAND flash market. This overcapacity situation will not only be due to Samsung’s huge spending for 3D NAND flash, but also to its competitors in this market segment (e.g., SK Hynix, Micron, Toshiba, Intel, etc.) responding to the company’s spending surge. At some point, Samsung’s competitors will need to ramp up their capacity or loose market share.
Samsung’s current spending spree is also expected to just about kill any hopes that Chinese companies may have of becoming significant players in the 3D NAND flash or DRAM markets. As our clients have been aware of for some time, IC Insights has been extremely skeptical about the ability of new Chinese startups to compete with Samsung, SK Hynix, and Micron with regards to 3D NAND and DRAM technology. This year’s level of spending by Samsung just about guarantees that without some type of joint venture with a large existing memory suppler, new Chinese memory startups stand little chance of competing on the same level as today’s leading suppliers.
Gigaphoton Inc., a manufacturer of light sources used in semiconductor lithography, announced its intention to draw up a new roadmap with the aim of improving the availability of the equipment, and also to respond to the needs of the semiconductor chip manufacturers who are being confronted with increasingly high demands.
Gigaphoton recently drew up a roadmap titled “RAM Enhancement” to enhance the Reliability, Availability, and Maintainability of the Excimer laser, a DUV light source. The company has already started off on overcoming the “99.8%-availability” barrier by 2020, which is the threshold limit value in the industry.
The availability of lithography tools is a key parameter which has a major impact on manufacturing IC chips. In line with this, maximizing the availability requires “long-term stable operation” and “minimized maintenance time.” To achieve both of the above, Gigaphoton is now striving to extend module lifetime and improve on-site unit serviceability that the company’s field engineers provide to customers, aiming at maintenance with the minimum number of machine stops.
To achieve “long-term stable operation,” the company is now increasing each lifetime of major modules such as the chamber (AMP CH), the line narrow module (LNM), and the monitor module (MM) up to 120 Bpls. As for “minimized maintenance time,” new software which automatically calculates expected unit lifetime and the right time for maintenance is ready to be introduced.
With these efforts, the company are now in the course of reducing the required number of maintenance down to only once per year as well as the mean time between module replacement down to half the conventional hours, and also overcoming the barrier of 99.8%-availability on every customer site by 2020. (This is on the assumption that memory chip makers use 60Bpls/year.)
Katsumi Uranaka, President & CEO of Gigaphoton commented, “Along with the increasing demand for semiconductor chips in recent years, the availability of semiconductor manufacturing equipment is becoming increasingly important. The ‘RAM Enhancement’ roadmap which we are promoting was formulated in order to meet these customer needs. From now on as well, Gigaphoton will continue to provide the optimum solutions, while taking into consideration the demands of our customers and also the market trends. ”
