Why is the memorizer the wind vane of the industryThe memorizer usually includes DRAM, NAND, NOR and SRAM. Often divided into two kinds in the semiconductor industry, DRAM and flashing memories. Because of its two major characteristic,can quantity production and last face width, be made at semiconductor of it unique statusing. Industry someone call it wind vane of the semiconductor industry.
Review the intersection of DRAM and history of development, nearly 8 to systemic circulation once every 10 years every, finally will certainly have bull the intersection of memorizer and factory’s backout, represent the end circulating. For instance backout such as TI and IBM for 1980 times; Toshiba for 1990 times, Hitachi and NEC backout, nowadays strange Damien’s backout at first of dreaming of of 2000 times. Up to retreat, send as an envoy to market, lack scene of monthly productivities.
In the whole world in the size of the silicon dice shifts, the memorizer walked in the forefront too, if DRAM hit the historical record up to 40 billion dollars of the annual sales amount under the promoting of windo95 in 1995, and begin to turn from 6 inches to production line of 8 inches, DRAM begins 8 inches of backout, and change direction 12 inches in 2007.
The industry thinks Damien’s backout very and dreams of, it is over not to represent the annexation of this wave of memorizers, there are getting too more still on producer on it is because global at present memorizer,such as Samsung, sea wrestler, lights beautiful, must reach and many Taiwan. Because of the characteristic of the memorizer industry, need high investment and quantity production. Factories newly building are all big super factories (superfab) at present ,Monthly productivity of 12 inches is about 150,000 slices, so there are already ample factories of 2-3 memorizers in the whole world, so does not think this wave has annexed it yet totally completely.
The industry want discuss it can be about whole industrial and undulating why the memorizer have such great might?
The global DRAM market is by 2001 since 1996 crash, the protagonist of global semi-conductive equipment investment is a logic chip trader represented by Intel.
But the chip of the processor began to enter 90 nanometers after 2002, Intel changed the tactics that improved primary frequency in the past, and turn to and reduce the power consumption and improve the function. At this moment, because of the increase in demand of the market, the investment proportion of the global memorizer increases day by day. If global memorizer investment in 2005 increases by 40%; Increased by 15% in 06; Increased in 30% and 08 and dropped by 20% in 07. The capital expenditure of the global memorizer accounts for the proportion of the sales amount, is up to 73% in 2007, even if drop and up to 44% in 2008.
Following two table show memorizer make the investment take semi-conductive percentage of gross investment and memorizer invest constitute proportion of its sales amount separately, it is obvious the weight proportion of the memorizer in the whole world semiconductor industry accounts for the first, so it is reasonable to be called industry’s wind vane.
In addition, SEMI statistics show, estimate the productivity of the global silicon dice will increase by 11% compared with 07 in 2008, among them the productivity of the memorizer increases by 41%, and the memorizer productivity increased by 38% in 07. 5 great investment plans of founding the factory ago the whole world of 2008, are all memorizers without exception, brilliant and auspicious and brilliant for Toshiba / new emperor, Samsung, sea wrestler, strength respectively.
In addition, in terms of Moore law of tracing, forefront the most that NAND flashing memory has walked, has already reached 4x-3xnm, secondly it is DRAM that reaches 5x-6xnm. Therefore, promote a lot of semi-conductive apparatus such as lithography machine, etching machine,etc. to customize for memorizer industry specially.
Rick Hill of Novellus speaks correctly, in 1980 times, 2/3 of the chip factories in the world make MPU, logical circuit, 1/3 of the chip factories make the memorizer; Come over instead nowadays, 2/3 of the chip productivity global make the memorizer.
So, no matter from technical advance, or the investment and expansion of productivity, the whole world relied on the memorizer industry, so the memorizer became status of protagonist of the global semiconductor industry and the left and right semiconductor industry can be already obvious.
After the financial crisis, global economy has already risen from the valley bottom under government’s joint efforts of various countries gradually, the semiconductor industry is the same too, it is estimated over 10% of the growth of 2010. Among them the manifestation of the memorizer confirms this point too, such as the memorizer price rises by 65% during Q1 to Q4 of 09, cause most memorizer factories to begin to make a profit. The industry is expected, the stock of the global memorizer will be still tight slightly in 2010, so the price continues rising is a trend, therefore the sales amount of the global memorizer DRAM may have 10% growth and NAND flashing memory sales amount and have 25% growth.
Desarrollan un sistema combinado para generar energía
Fujitsu Laboratories Ltd. da un paso más en la generación de energía eléctrica a partir de la luz y el calor. Dejando atrás los sistemas combinados, el proyecto de Fujitsu permite generar electricidad a partir de dos fuentes diferentes de una manera económica, abriendo la puerta al uso generalizado de estas tecnologías en diversos ámbitos. Sin necesidad de cables ni de reemplazos de la batería, podría extenderse fácilmente a regiones y aplicaciones desatendidas o como fuente de alimentación para tecnologías médicas.
Esta modalidad de recolección energética permite solventar problemas derivados de la escasa potencia que se puede generar de manera individual, que obligaban hasta ahora a una combinación de sistemas con el consiguiente aumento de los costos. En este caso, al permitir una fabricación a partir de materiales orgánicos económicos, el costo permanece bajo.
Para llevar a buen puerto las investigaciones, Fujitsu utilizó dos materiales semiconductores diferentes. El semiconductor de tipo N recoger energía de la luz. El semiconductor de tipo P recoge la energía del calor. Los circuitos eléctricos pueden cambiar de un modo a otro y se componen de un material orgánico que funciona como un generador para la recolección en ambos modos: fotovoltaica y termoeléctrica. De esta manera, se duplica el potencial energético de captación, capacitando al dispositivo para equipar sensores médicos sin baterías ni cableado o para dar soporte a sensores meteorológicos en zonas remotas. Y aunque los primeras experiencias han tenido éxito, todavía habrá que esperar para poder implantar este sistema de manera comercial al menos hasta el año 2015, fecha en la que se espera que esta tecnología esté lista para comercializarse.
Neurons Used in Working Semiconductor
German researchers at the Max Planck Institute for Biochemistry in Munich, Germany have constructed a working semiconductor that uses snail neurons.
Future hybrid neuron-semiconductor chips will consist of complex neural networks that are directly interfaced to electronic integrated circuits. They will help us to understand the dynamics of neuronal networks and may lead to novel computational facilities. Here we report on an elementary step towards such neurochips. We designed and fabricated a silicon chip for multiple two-way interfacing, and cultured on it pairs of neurons from the pedal ganglia of the snail Lymnaea stagnalis. These neurons were joined to each other by an electrical synapse, and to the chip by a capacitive stimulator and a recording transistor. We obtained a set of neuroelectronic units with sequential and parallel signal transmission through the neuron-silicon interface and the synapse, with a bidirectionally interfaced neuron-pair and with a signal path from the chip through a synaptically connected neuron pair back to the chip. The prospects for assembling more involved hybrid networks on the basis of these neuroelectronic units are considered.
