Compact Multi-Level Digital-to-Analog Conversion Using Thin-Film Multimodal Transistors

Unlike conventional ohmic contact thin-film transistors (TFTs), contact-controlled TFTs [1], [2] rely on source energy barriers to produce a range of benefits including: low saturation voltages; extremely high intrinsic gain; power-efficiency; electrical stability; and uniformity of operation, notably with imprecise processes [3]. Generally, these benefits come at the expense of transconductance, however in materials such as polysilicon, similar levels of on-current can be obtained in a more compact footprint without any trace of kink-effect [4], [5].

TCAD Applications Engineering Intern

Location: United States
Silvaco is looking for interns to join the TCAD Group. As part of this internship, the interns will work to update and expand Silvaco’s TCAD example set and update product documentation. The intern will gain skills and become more proficient in Semiconductor Device Modeling as well as technical writing and technical presentation. Furthermore, interns will have an opportunity to pursue some independent research work utilizing Silvaco tools that could align with graduate research studies. We are looking for a curious, open-minded spirit.

Investigation and Explanation of PiPiN Avalanche Photo-Diode Characteristics

In this article, the operation of avalanche photo-diodes in the medium gain, continuous operation mode is investigated. In other words, we are not considering diode operation in transient “Gieger” or “single photon” detection mode, but rather in a region safely below secondary breakdown, where a well-designed avalanche photo diode can exhibit a moderate photo-generated current multiplication factor of an order of magnitude or higher.
