接下来,BLC(Bit Line Contact)阶段会在单元区内创建ISO与列地址线路(Bit Line)2之间的连接。GBL(Peri Gate+Cell Bit Line) 阶段将同时创建单元列地址线路与外围3中的栅极。 SNC(Storage Node Contract)阶段继续创建有源区域和存储节点4之间的连接。随后,M0(Metal0)阶段形成外围S/D(Storage Node)5的连接点以及...
More specifically, applying the HKMG process to mobile DRAM peripheral (peri) transistors posed a major challenge. DRAMs typically consist of cell transistors which store data and peri transistors which conduct data input and output. It is therefore necessary to minimize the impact of the HKMG proce...
Full chip integration with 5-layered cell stacked on peri -core wafer is successfully demonstrated for the first time, offering superior on -current performance and gate controllability. A novel process integration scheme using Si/SiGe sacrificial multilayers and hybrid wafer bonding technique is ...
2D NAND到4D NAND的发展概念图 来源:SK海力士 公开资料显示,SK海力士目前的4D NAND采用了PUC(PeriUnder Cell,单元下外围)技术,将外围控制电路放置在存储单元的下方,较更传统的外围电路侧置设计可减少芯片占用空间。而SK海力士未来的NAND将在两块晶圆上分别制造外围电路和存储单元,此后采用W2W(晶圆对晶圆)形式的混合键...
CONSTITUTION: A plurality of transistors(240) is formed on a semiconductor substrate(200) with a cell region and a core/peri region defined thereon. A contact pad(260) is formed on both sides of the transistor. The first interlayer dielectric(280) is formed on the resultant substructure. A ...
Many bit cells consist of a single component (like a resistor, capacitor, or transistor), but they need a way to be shut off so they’re not accidentally disturbed when another related cell is accessed. For this reason, an additional “selector” transistor is added to every bit cell, ...
and the presence of positive cytoplasmic staining forDRAMwas also considered a positive outcome. Our result showed a strong punctate cytoplasmic expression ofLC3B,SQSTM1/p62, and HGGs compared to LGGs and peritumoral non-glioma tissue.DRAMalso exhibited positive and negative cytoplasmic staining (Fi...
(Patient 8), OCT images revealed perifoveal disruption of the ellipsoid zone, which suggests that the initial impairment began in the photoreceptor layer [12]. On the other hand, considering that autophagy in RPE is important for the degradation of the outer segments of photoreceptors, the ...
