This paper describes the new write/erase operation methods in order to improve the read disturb characteristics for flash EEPROM cells which are written by channel hot electron injection and erased by F-N tunneling emission from the floating gate to the substrate. The new operation method is either applying a reverse polarity pulse after each erase pulse or applying a series of shorter erase pulses instead of a long single erase pulse. It is confirmed that by using the above operation method, the leakage current can be suppressed, and then the read disturb life time after 10/sup 5/ cycles W/E operation is more than 10 times longer in comparison with the conventional method.<>
本文介绍了一种新的写/擦除操作方法,该方法采用通道热电子注入写入,并通过浮栅到衬底的F-N隧穿发射擦除,以改善闪存EEPROM单元的读干扰特性。新的操作方法是在每个擦除脉冲之后应用一个反向脉冲,或者应用一系列较短的擦除脉冲而不是长单擦除脉冲。结果表明,采用上述操作方法,可以有效地抑制漏电流,并使10/sup 5/ cycles W/E操作后的读扰寿命比常规方法延长10倍以上。

We report experimental measurements of the brightness of an electron beam produced by a ferroelectric cathode. The brightness value of B/sub n/ = 1.2x10/sup 1/1 A/m/sup 2/ rad/sup 2/ for a 15A, 1OkV beam exceeds that obtained from thermionic cathodes operating at comparable voltages. To our knowledge, these are the first reported measurements of the beam quality (emittance and brightness) of the electron beam from a ferroelectric cathode.<>

Phase-shifting mask topography effects on lithographic image quality 相移掩模地形对光刻图像质量的影响
Pub Date : 1993-08-08 DOI: 10.1109/IEDM.1992.307307

The impact of phase-shifting mask topography on wafer exposure was studied via simulations and experimentation using phase-shifting masks fabricated by etching the quartz to define the shifted areas. The influence of the refractive index of the chromium layer and of the profile of the chromium patterns was shown to be minimal. On the other hand, the quartz profiles have a large impact on the wafer results. For vertical quartz profiles, the intensity of the light going through the etched portion of the mask is lower than that going through the unetched portion of the mask and varies with feature size. This problem can be addressed either by optimizing the quartz profiles or by biasing the size of the features depending on the type of pattern.<>
通过模拟和实验,研究了移相掩模形貌对晶圆曝光的影响。铬层的折射率和铬图案的轮廓的影响被证明是最小的。另一方面,石英剖面对晶圆结果有很大的影响。对于垂直石英剖面,通过掩模蚀刻部分的光强度低于通过掩模未蚀刻部分的光强度,并且随特征尺寸的变化而变化。这个问题可以通过优化石英剖面或根据图案类型偏置特征的大小来解决。

A fully planarized multilevel interconnection technology using selective TEOS-Ozone APCVD 一种采用选择性TEOS-Ozone APCVD的全平面化多层互连技术

A new interlayer dielectric film planarization technology for sub-half-micron multilevel interconnections has been developed. This technology utilizes a new selective TEOS-Ozone APCVD SiO/sub 2/ film formation technique which can be realized by differences in surface adsorption properties and flow characteristics of siloxane oligomers. The deposition rate can be reduced by putting Ti or its alloy metal films such as TiN and TiW on top of Al wirings. These metal films can reduce the oligomer adsorption and assist the oligomer flow into the spacings between Al wirings. Furthermore, the selectivity is enhanced by a CF/sub 4/ gas plasma pre-treatment, even on top of the W films. The TEOS-Ozone APCVD SiO/sub 2/ films deposited on the Ti/Al, TiN/Al, TiW/Al or W/Al wirings with the CF/sub 4/ pre-treatment were more than 40% thinner than those on PECVD SiO/sub 2/ under-layers. Higher capability for both local and global planarization of interlayer dielectrics was confirmed in a multilevel metallization scheme in the double-level Al interconnection technology with the 0.6 mu m design rule and in a prototype 64M DRAM fabrications.<>
提出了一种用于亚半微米多层互连的层间介质膜平面化新技术。该技术采用了一种新的选择性正硅氧烷-臭氧APCVD SiO/sub 2/膜形成技术,该技术可以通过硅氧烷低聚物的表面吸附性能和流动特性的差异来实现。将Ti或其合金金属薄膜(如TiN和TiW)涂覆在Al导线上可以降低沉积速率。这些金属薄膜可以减少低聚物的吸附,并帮助低聚物流入铝导线之间的间隙。此外,通过CF/sub - 4/气等离子体预处理,选择性得到了提高,即使是在W膜的顶部。经CF/sub - 4/预处理后,在Ti/Al、TiN/Al、TiW/Al或W/Al上沉积的TEOS-Ozone APCVD SiO/sub - 2/薄膜比PECVD SiO/sub - 2/下层薄40%以上。在设计规则为0.6 μ m的双级Al互连技术中的多层金属化方案和原型64M DRAM制造中,证实了层间介电体局部和全局平面化的更高能力。

In order to realize minimum pitch interconnections without degrading reliability, self-aligned contacts (SACs) between interconnections and plugs are necessary. The planarized interconnections with SAC plugs is formed for quarter-micron size as follows. Interconnection trenches and contact holes are formed using a self-aligned etch-stop layer, followed by simultaneous metal-filling into the trenches and contact holes. Si-rich oxide (SRO) films are found to be promising for a self-aligned etch-stop layer with their high etching selectivity to SiO/sub 2/ as high as 10-30. Sufficiently low line resistance of 15 k Omega /cm and low contact resistance of 70 Omega /contact are obtained with the quarter-micron W-interconnection with the SAC plugs.<>

This work investigates the kinetics of arsenic deactivation at temperatures from 500 to 800 degrees C and for concentrations between 1*10/sup 20/ and 1*10/sup 21//cm/sup 3/. Using profiles created by repeated laser melt annealing, we determine mobility as a function of both active and inactive dopant concentration and then characterize the dynamics of carrier deactivation. We observe retrograde resistivity versus concentration at high doses, which is explained by a mobility reduction due to the inactive arsenic and by retrograde electrical activity of the dopant itself.<>
本研究研究了温度为500至800℃、浓度为1*10/sup 20/和1*10/sup 21/ cm/sup 3/之间的砷失活动力学。利用重复激光熔融退火产生的轮廓,我们确定了迁移率作为活性和非活性掺杂浓度的函数,然后表征了载流子失活的动力学。在高剂量下,我们观察到电阻率随浓度的逆行变化,这可以解释为由于非活性砷引起的迁移率降低和掺杂剂本身的逆行电活性。

An extremely high power three-section second-harmonic 35 GHz gyro-TWT has been designed with a self-consistent nonlinear simulation code (1). An output power of 530 kW with 21% efficiency, 54 dB gain and 6% bandwidth is predicted. To substantiate the claim that a harmonic gyro-TWT can generate significantly higher output power with better stability than fundamental gyro-TWTs due to the higher beam currents allowed for the weaker harmonic interaction, a proof-of-principle Ku-band experiment is being constructed at UCLA with comparable performance predicted.

This paper reports the development of double recessed pseudomorphic GaAs High Electron Mobility Transistors (HEMTs) for high voltage operation. The GaAs-based power HEMT with 0.25 mu m gate-length exhibited a gate to drain breakdown voltage of 30 volts, a peak g/sub m/ of 510 mS/mm, and a maximum current density of 540 mA/mm. When biased to 14 volts on the drain, the 400 mu m wide HEMT delivered 505 mW (1.26 W/mm) output power at 4.5 GHz. This is the highest output power density and drain-source operating voltage ever reported for HEMT devices. The device also showed excellent 4.5 and 10 GHz power performance combination (power gain, power density, power-added efficiency) at V/sub ds/=8V. The significant extension of device drain bias range as well as increase in the product of current density and breakdown voltage were attributed to the adoption of channel recess using reactive ion etching.<>
本文报道了用于高压工作的双凹槽伪晶砷化镓高电子迁移率晶体管(hemt)的研制。栅极长度为0.25 μ m的gaas基功率HEMT的栅漏击穿电压为30伏,峰值g/sub /为510 mS/mm,最大电流密度为540 mA/mm。当漏极偏置到14伏时,400 μ m宽的HEMT在4.5 GHz下提供505 mW (1.26 W/mm)的输出功率。这是HEMT器件有史以来最高的输出功率密度和漏源工作电压。该器件在V/sub /=8V时也显示出出色的4.5 GHz和10 GHz功率性能组合(功率增益、功率密度、功率附加效率)。器件漏极偏置范围的显著扩大以及电流密度和击穿电压乘积的显著增加是采用反应离子蚀刻的沟道凹槽的结果。

The GaAs-based power HEMT with 0.25 mu m gate-length exhibited a gate to drain breakdown voltage of 30 volts, a peak g/sub m/ of 510 mS/mm, and a maximum current density of 540 mA/mm. When biased to 14 volts on the drain, the 400 mu m wide HEMT delivered 505 mW (1.26 W/mm) output power at 4.5 GHz. This is the highest output power density and drain-source operating voltage ever reported for HEMT devices.
