A 128Mb SOI DRAM with FBC (floating body cell) has been successfully developed for the first time. Two technologies have been newly implemented. (i) In order to realize full functionality and good retention characteristics, the well design has been optimized both for the array device and the peripheral circuit. (ii) Cu wiring has been used for bit line (BL) and source line (SL), which leads to increasing the signal of the worst bit in the array and also realizes the full compatibility with 90nm CMOS technology, IEEE - 90nm node CMOSプロセスによる128Mb-FBC(Floating Body Cell)メモリの技術開発

The memory cell characteristics of the FBC (Floating Body Cell) have been experimentally verified by 0.175 /spl mu/m cell array for the first time. The FBC is a one-transistor gain cell, which is a suitable structure for the future embedded DRAM on SOI wafer. The memory cell layout and the process integration have been designed from the viewpoint of the logic process compatibility without sacrificing the data retention characteristics. The salicide process with the poly-Si plug is implemented into the process integration. The most important device characteristics for realizing the FBC is the threshold voltage difference (/spl Delta/ Vth) of the cell transistor between "1" state and "0" state. The key device parameters in order to enlarge the /spl Delta/ Vth are experimentally clarified. A /spl Delta/ Vth of 0.4 V has been obtained, which leads to 99.77% function bit yield of 96 Kbit ADM (Array Diagnostic Monitor). The retention time of 5 sec has been realized at the room temperature., Japan Soc. Applied Phys - A memory using one-transistor gain cell on SOI(FBC) with performance suitable for embedded DRAM's

A 288 Kbit memory chip featuring a one-transistor gain cell on SOI of the size 0.21 /spl mu/m/sup 2/(7F/sup 2/ with F=0.175 /spl mu/m) which we named the floating body transistor cell (FBC) is presented and basic characteristics of the cell and the memory chip performance are disclosed. The threshold voltages of a cell transistor in the chip for the data "1" and for the data "0" are measured by using a direct access test circuit and a fail bit map for the 96 Kbit array is obtained. A sensing scheme which was designed to eliminate the effect of cell characteristics variation due to process and temperature fluctuation as common mode noise is verified to be working and the random access time is measured to be less than 100 ns. The characteristics of data hold demonstrate that the FBC can satisfy retention time specifications for some embedded memories. The access time and the data retention time show that the FBC has a potential to be used as a future embedded DRAM memory cell., Japan Soc. Appl.

A novel FBC with 25nm-thick BOX (buried oxide) structure has been developed. A feature of new FBC is scalability in the case of thinner SOI, which promises embedded DRAM on SOI in future generations. Using 96Kbit array, the pause time distribution of FBC is demonstrated for the first time. Due to simplified structure, pause time variation of new FBC is significantly suppressed compared with conventional FBC., IEEE - Analysis of process margins for emitter-base self-alignment structures through a combination of simulation and experiment

The process margins of an emitter-base self-alignment structure were analyzed using two-dimensional simulations and experiments. The margins were obtained quantitatively in terms of ECL propagation delay time. It was found that the margin for emitter opening overetching was very large when the intrinsic base impurity was introduced before base sidewall formation. Misalignment of the emitter opening and the base opening was also analyzed. It was found that an alignment error of less than 0.2 mu m, which is within the misalignment margin of currently available steppers, does not lead to serious problems. >, IEEE - SOI上に形成した混載DRAM用メモリセル-FBC(Floating Body Cell)-

Three dimensional mechanical stress simulation has been applied to the trench isolation structure for bipolar LSIs. The accuracy of the simulation was confirmed by the micro Raman measurements of the actual trench structure. Considering the three dimensional analysis of the dislocation formation in the silicon crystal, there are 4 different {111} gliding planes at each point, and 3 specific gliding directions for each {111} plane along which the dislocation of silicon occurs. Thus 12 gliding directions exist at each point. Resolved shear stresses along the 12 directions have been calculated by the simulation. The simulated results basically agree with the results of dislocation formation in the experiment. This method is a very useful tool to analyze the dislocation or defect formation along {111} gliding planes of the trench isolation structure. >, IEEE - 0.3 μm BiCMOS technology for mixed analog/digital application systems

Optimization of fmax and VA values was investigated by changing Wcpi and NB Values of low temperature LP-CVD epitaxial base. It was found that there are optimum conditions which can realize concurrent extremely high fmax value-more than 50 GHz-and extremely high Vn value-more than 50V-in the case of silicon epitaxial base bipolar transistors with silicided emitter and base electrodes. Relatively flat profile of boron in the epitaxial base region can realize high Vn value with high fmax. NiSi emitter and base electrodes technology can further increase the fmax value. The highest fmax value of 62.86 Hz at a collector current of 1.7 mA was achieved. High BVCBO of 4.7 V, high VA of 85.7 V and low p/sub BI/ value of 8.5 k/spl Omega//sq were also realized at the same time., Japan Soc. Appl. Phys - 90nmノード高性能部分空乏型SOI CMOSデバイス

In this paper, a 0.3-/spl mu/m BiCMOS technology for mixed analog/digital application is presented. A typical emitter area of this technology is 0.3 /spl mu/m/spl times/1.0 /spl mu/m. This technology includes high f/sub max/ of 37 GHz at the low collector current of 300 /spl mu/A and high BV/sub ceo/ of 10 V NPN transistor, CMOS with L/sub eff/=0.3 /spl mu/m, and passive elements. By using the shallow and deep trench isolation technology and nonselective epitaxial intrinsic base, the C/sub jc/ can be reduced to 1.6 fF, which is the lowest value reported so far. As a results, we have managed to obtain the high f/sub max/ at the low current region and high BV/sub ceo/ concurrently. These features will contribute to the development of high-performance BiCMOS LSI's for various mixed analog/digital applications., Institute of Electrical and Electronics Engineers (IEEE) - 半導体装置およびその製造方法

Reducing parasitic capacitance and resistance is an effective means of both improving ECL gate delay and increasing f/sub T/ values. In this paper, we demonstrate a device with sub-20 ps t/sub pd/ values even at f/sub T/=23 GHz, a performance which has been achieved by implementing a number of techniques. These include 1) low-stress deep- and shallow-trench isolation to reduce C/sub CB/, 2) a low-concentration collector design to reduce C/sub CB/, 3) NiSi-salicided base and emitter electrodes to reduce R/sub B/, and 4) a shallow base formed by double diffusion technology for relatively high f/sub T/ with a low-concentration collector design. The low-concentration collector design gives the device a high breakdown voltage of 6.2 V. >, Institute of Electrical and Electronics Engineers (IEEE) - シリコンバイポーラトランジスタにおける低消費電力化の検討
