Seems like the Intel has decided to come up with something new in the chip mnaufacuring technology each and every day. While the news of the new versions of Atom and core i7 processors has not even got off from the charts, company has come up with another news. As far as the chip manufacturing technology is concerned, I think this is quite of a news. Intel has announced that the upcoming processor chips will be based on the 3D transistors.
The structure of a 3D transistor differs from that of a usual transistor. In this transistor theplanar or flat gate is replaced with a three dimensional gate. The strucrure is such that a thin fin rises vertically upwards from the silicion substrate. The image shows the rin rising upwards. The gate is contructed so ad to cover the fin from three sides viz, the right, left and the top. Now this is contraty to the 2D transistor where the gate covers the base from one side only. The reason behind this is to enable more flow of current while in the 'on' stage and also to switch off the transistor more quikly . All this is done to improve the transition time between the 'on' and 'off' stages of the transistor.
