摘要:
对于传统的硅MOS场效应晶体管,器件跨导的大小正比于沟道的宽长比.本文在石墨烯晶体管中发现了相反的现象.制备了源漏之间距离相同,且沟道宽度相同的石墨烯晶体管,实验结果为沟道较长的晶体管跨导较大.究其原因,石墨烯晶体管中栅电极覆盖的沟道面积较大时,被感应的载流子数量较多,所以跨导较大.此实验结果和分析对石墨烯晶体管的进一步理解和应用有明显的意义.

摘要:
南京电子器件研究所成功制备了一种W波段的GaN三级放大电路。采用电子束直写工艺制备了栅长为100 nm的AlGaN/GaN T型栅,其结构见图1。直流测试最大电流密度为1.3 A/mm,最大跨导为430 mS/mm;小信号测试外推其fT和fmax分别为90 GHz及210 GHz(如图2所示)。采用该工艺制备的三级放大电路在75-110 GHz进行测试,其最大小信号增益为21 dB(如图3所示)。该单片在90GHz处的最大输出功率可达1.117 W(如图4所示),功率附加效率为13%,功率增益为11dB。

摘要:
分析了双轴应变Si p型金属氧化物半导体场效应晶体管(PMOSFET)在γ射线辐照下载流子的微观输运过程,揭示了γ射线的作用机理及器件电学特性随辐照总剂量的演化规律,建立了总剂量辐照条件下的双轴应变Si PMOSFET阈值电压与跨导等电学特性模型,并对其进行了模拟仿真。由仿真结果可知,阈值电压的绝对值会随着辐照总剂量的积累而增加,辐照总剂量较低时阈值电压的变化与总剂量基本呈线性关系,高剂量时趋于饱和;辐照产生的陷阱电荷增加了沟道区载流子之间的碰撞概率,导致了沟道载流子迁移率的退化以及跨导的降低。在此基础上,进行实验验证,测试结果表明实验数据与仿真结果基本相符,为双轴应变Si PMOSFET辐照可靠性的研究和应变集成电路的应用与推广提供了理论依据和实践基础。%In this work, the carrier microscopic transport process of biaxial strained Si p-channel metal-oxide-semiconductor field-effect transistor (PMOSFET) underγ-ray radiation has been studied. Effect ofγ-ray on devices and the relationship between the variation of device electrical characteristics and the total dose are investigated. A model for considering the degradation of threshold voltage and transconductance due to the total dose radiation is established. Based on this model, numerical simulation has been carried out. Results show that the threshold voltage of PMOSFET decreases with increasing radiation dose. At a lower total dose, the threshold voltage decreases linearly. However, at a higher total dose, it becomes saturated. The degradation can be explained by the generation of trapped charges which increase the impact possibility of carriers in the channel and induce the reduction of mobility and transconductance accordingly. Finally, the simulation results are compared with the experimental data. A good agreement is observed, indicating the validation of our proposed model.

摘要:
An analytical model for drain current of high-k gate dielectric fully-depleted nanoscale germanium-on-insulator (GeOI) p-channel metal-oxide-semiconductor field-effect transistor (PMOSFET) is established by solving two-dimensional Poisson’s equation to derive the surface potential and inversion charge in the channel region. This drain current model includes velocity-saturation, channel-length modulation and mobility-modulation effects;and it simultaneously considers the impacts of the interface-trapped charges at both gate oxide/channel and buried oxide/channel interfaces and the fixed oxide charges on the drain current. A good agreement between the simulated drain current and experimental data is achieved in both the saturation and non-saturation regions, confirming the validity of the model. Using the model, the influences of the main structural and physical parameters on transconductance, output conductance, cut-off frequency, and voltage gain of the device are investigated. These can be served as a guide for the design of the GeOI PMOSFET.%通过求解沟道的二维泊松方程得到沟道表面势和沟道反型层电荷,建立了高k栅介质小尺寸绝缘体上锗(GeOI) p型金属氧化物半导体场效应晶体管(PMOSFET)的漏源电流解析模型。模型包括了速度饱和效应、迁移率调制效应和沟长调制效应,同时考虑了栅氧化层和埋氧层与沟道界面处的界面陷阱电荷、氧化层固定电荷对漏源电流的影响。在饱和区和非饱和区,漏源电流模拟结果与实验数据符合得较好,证实了模型的正确性和实用性。利用建立的漏源电流模型模拟分析了器件主要结构和物理参数对跨导、漏导、截止频率和电压增益的影响,对GeOI PMOSFET的设计具有一定的指导作用。
