Webinar on TFT and FPD Design

Webinar on TFT and FPD Design

I knew that the acronym for TFT meant Thin Film Transistors, but I hadn’t heard that FPD stands for Flat Panel Detectors. It turns out the FPD are solid-state sensors used in x-ray applications, similar in operation to image sensors for digital photography and video. I’ll be attending and blogging about what I learn… Read More

Two weeks ago I blogged about amorphous silicon and how that material is well-suited for designing TFTs. Today I’m following up after watching the archived webinarpresented by Nam-Kyun Tak of Silvaco. After clicking on that link you’ll be brought to a brief sign-up page and then can watch the archived webinar in your… Read More


Amorphous Silicon and TFTs

Amorphous Silicon and TFTs

Most ICs are fabricated with crystalline silicon (c-Si), which is a tetrahedral structure forming a well-ordered crystal lattice. There’s another form of semiconductor material called amorphous silicon (a-Si) which has no long-range periodic order. It turns out that a-Si is a great material for the active layer in thin-film… Read More

Traditionally logic devices built on top of thin-film-transistors (TFTs) have used one type of device, either an NMOS a-Si: TFT (hydrogenated amorphous silicon) or a PMOS organic device. Recently a-Si:H and pentacene PMOS TFTs have been integrated into complementary logic structures similar to CMOS. This, in turn, creates… Read More
