​
Imec is developing a smart platform based on a 2D array of ultrasound transducers connected to thin-film transistor technologies. This platform envisions to generate haptic feedback in mid-air or to become a next-generation medical imaging device. Key applications for such ultrasound transducer arrays are medical imaging, fingerprint scanning, directed audio and gesture recognition.

The transducer platform is connected to a thin-film transistor array consisting of low-temperature polycrystalline silicon transistors with charge carrier mobilities above 100 cm2/Vs. Typical transistor dimensions are in the low micrometer range.


Previous PhD topics have demonstrated feasibility of such arrays for low frequency (100s kHz) applications in mid-air. The goal of this PhD is to elaborate driving and read-out schemes for 2-5MHz ultrasound arrays focusing on biomedical applications, such as high-frequency medical imaging and powering of ultrasound ingestible devices. The PhD student will perform detailed system level study of thin-film transistor-based ultrasound arrays for those applications, differentiating the in-pixel circuit complexity by thin-film transistors and the silicon CMOS peripheral circuits. In addition to design, the PhD student will also be responsible for the circuit and matrix measurements, comparison of experiments and modelling. Designs will be processed in the available foundry technologies.

​
LiDAR (Light Detection and Ranging) is a method for determining distances by targeting an object with light and measuring the time for the reflected light to return to the receiver. With the rapid development of machine learning and image signal processing technology, LiDAR is expanding its application to various fields and is receiving a lot of attention, especially in automotive (autonomous driving) and AR/VR applications.

Current mainstream LiDAR (i.e. direct time of flight using SPAD) technology has limitations. Noise arising from the ambient light and insufficient active light signal due to eye-safety restriction are a few of those limitations. FMCW LiDAR has the potential to overcome these limitations since the continuous-wave operation avoids eye hazards (as high peak powers are no longer needed) while the coherent detection provides immunity to interference from solar glare and other light sources—including lidars used by other cars.

However, the huge potential that the optical coherent detection offers to enable long-range, high-resolution FMCW Lidar systems has not yet been realized into its full application potential. Therefor advanced silicon design techniques should also be used, as have been done in the past in imec’s 140 GHz FMCW radar systems.

Imec has a good track record in developing building blocks of the FMCW LiDAR, such as light sources and photodetectors, and is also known as one of the best design houses of FMCW radar. The goal of this PhD is to develop a FMCW LiDAR readout IC by fully valorizing all the underlying technologies of Imec.  You will design the FMCW readout IC and collaborate with the Imec optical experts and other researchers to build a high-resolution FMCW LiDAR system.

Introduction
Light detection and ranging (LiDAR) systems enable depth imaging in applications such as automotive, robotics and industrial automation. Emerging LiDARs focus on full solid-state architectures (for illumination, scanning and detection) with frequency-modulated continuous-wave (FMCW) optical engines. The increasing interest in using coherent detection approaches in SWIR wavelengths (e.g. around 1550 nm) brings advantages such as detection range, eye safety, and immunity to environmental radiation (when compared to direct time-of-flight systems in NIR wavelengths). Furthermore, ongoing developments at imec in on-chip integration of light sources, solid-state beamsteering, low-power fast phase shifters, and photodetectors on Si/SiN photonic platforms create the route for fully integrated solid-state low-cost low-power LiDAR photonic integrated circuits (PICs). One of the challenges in building such systems is the large amount of data that needs to be acquired and processed in a short time (10s of millions of samples per second).

Topic
This scaling problem can be overcome by developing FMCW imaging arrays for massively-parallel data acquisition and readout, with on-chip data processing at the pixel level. This approach requires a photonic platform where vertically-incidence SWIR photodetectors are efficiently coupled with the FMCW local oscillator (LO) reference signal and remaining photonic building blocks. The main purpose of this PhD position is to develop a new platform for performing PIC-based mixing of the LO and detected optical signals, with optical efficiency beyond the current state-of-the-art. This will subsequently enable FMCW-capable imaging arrays for LiDAR. The required tasks involve system modelling, photonic component simulations, PIC design and layout, optical characterization, and system demo. The candidate will work in a large and dynamic team of experts in photonic design, IC design and system architecture.

The candidate
We are looking for a highly motivated recent graduate holding a master’s degree in photonics, physics, electrical engineering, or related field. The candidate must have an interest in design, modeling, and characterization of optical systems. Scripting and programming skills are a plus. The candidate is expected to report regularly on the progress and to be a team player, interacting closely with other team members. Good communication skills and excellent knowledge of English are also required, as you will work in an international, multidisciplinary and multicultural team spanning several imec departments.

​
Integrated circuits based on flexible thin-film transistors have received lots of attention due to recent progress in literature and the pioneering of multi-project wafers in thin-film transistor foundries. Low temperature polycrystalline silicon (LTPS) transistors are very attractive due to the possibility of having a full complementary CMOS flow on flexible substrate, having charge carrier mobilities exceeding 50 cm²/Vs for p-type devices. The main applications for those transistors cover a broad range from are to be employed in-pixel switches, drivers and/or amplifiers, to peripheral circuits as found in displays and imagers.


The goal of this PhD topic is to elaborate several mixed-signal integrated circuits, such as amplifiers, analog-to-digital converters and memory read/write circuits in Low Temperature Polycrystalline Silicon (LTPS) technologies. The PhD student will perform detailed system level study of thin-film transistor-based integrated circuits for several applications in order to realize these circuits within specification. It will be important to also understand the opportunities and overcome the challenges specific to those technologies. In addition to design, the PhD student will also be responsible for the integrated circuit measurements, comparison of experiments and modelling. Designs will be processed in the available foundry technologies.

Electro-wetting technologies for dielectric microfluidic devices are very appealing for life science applications, as they provide solutions to control microdroplets containing biological cells in an efficient way enabling early detection of specific cells. There is a huge gain to bring this platform to larger glass substrates, enabling light-field imaging and integration of thin-film transistor smart pixels.

The goal of this PhD topic is to analyze several electro-wetting architectures for life science applications, whereby droplet-driving and -controlling is an important aspect next to the detection of the droplet inside a pixel, e.g. by adding local impedance measurements in the array. The PhD student will perform detailed system-level study of thin-film transistor-based electro-wetting devices. Moreover, several design solutions have to be elaborated for different available technologies, ranging from amorphous Silicon towards LTPS. It will be important to also understand the challenges of each technology and design the specific circuit and array architecture.

Design and characterization of in-panel charge-sense amplifier for sensor array readout
Thin-film transistors (TFTs) are currently the dominant technology for in-pixel switches in flat-panel displays. The
current trends drives TFT devices to deliver more complex functions than simply switching, like in integrated TFTbased
row selector circuit enabling to reduce the bezels. TFT circuits can be fabricated on large substrates, thereby
creating very thin, lightweight and ultra-flexible electronics. A flexible TFT-based microprocessor and a near-field
communication (NFC) tag have already been demonstrated. Also the field of analog electronics based on TFTtechnologies
is maturing

PhD researcher on ultralow power design techniques for thin-film VLSI circuits
The goal of this PhD is to elaborate ultralow power design techniques for flexible integrated circuits. The technology that we will use are transistors that are processed on flexible plastic substrates. They are based on amorphous oxide semiconductors, kin to the transistors used in the backplanes of AMOLED televisions, but processed on plastic. Our goal is to use them to make flexible integrated circuits with large integration densities, from LSI to VLSI. These flexible circuits will find applications in IoT and wearable patches that measure body functions.
The target thin-film circuits for IoT and wearables need to interact with standard electronics and readers (such as smartphone, bluetooth, ...). This requirement sets minimum specifications regarding power consumption, supply voltage and operating speed. The challenge in the research is to reach these despite certain technology performance limitations. Indeed, the semiconductor has a charge carrier mobility of about 20 cm2/Vs, and can only carry electrons, meaning that only n-type transistors exist. Furthermore, the transistor dimensions are not strongly scaled, and of the order of 0.5 to 2 microns.

PhD researcher on design of ultrathin image sensors using thin-film transistor matrix
Imec develops disruptive technologies for image sensors based on thin-film photodetectors. Ultra-thin, submicron active layers with absorption coefficients much higher than those of e.g. silicon enable new form factors and applications. When integrated with a thin-film transistor backplane, thin-film photodetectors can serve as a basis for large-area, flexible image sensors that find use in medical or industrial x-ray imaging, in consumer applications such as fingerprint or handpalm scanners, or for conformable, curved focal planes.
