School of Engineering Department of Electronic and Computer Engineering 154 Piezoelectric Micromachined Ultrasonic Transducers for Sensing and Imaging Supervisor: YANG Yansong / ECE Student: REN Junru / ELEC Course: UROP 1000, Summer Photolithography, other names called optical lithography, is a commonly used method for the manufacturing of integrated circuits and also a mainstream method in the semiconductor industry. Laser direct writing, also called multiphoton lithography, is another useful technique in various applications such as material processing and manufacturing. These are two prominent techniques in microfabrication. This literature review delves into the similarity and differences between photolithography and laser direct writing techniques in different applications. By discussing aspects like material precision, resolution, and features of output, this review aimed to provide a simplified overview of these two methods for beginners seeking a basic understanding of microfabrication technology. Open-Source Digital Integrated Circuit Design and Tapeout Supervisor: ZHANG Yihan / ECE Student: GU Liming / ELEC Course: UROP 1100, Fall UROP 2100, Spring UROP 3100, Summer The objective of this project is to create a (15,11) Hamming code encoder and decoder pair, equipped with UART (Universal Asynchronous Receiver/Transmitter), and have it tapeout as an integrated circuit (IC) chip using the tape-out service provided by tinytapeout.com. The purpose of this system is to ensure reliable data transmission by implementing error detection and correction mechanisms. This report will first give a brief introduction to the completed design. Then, the main focus will be the verification process of the functionality of the physical chip, returned from tinytapeout.com, using real-world equipment such as FPGA and logic analyzer. Open-Source Digital Integrated Circuit Design and Tapeout Supervisor: ZHANG Yihan / ECE Student: JING Shuangyu / CPEG Course: UROP 1100, Summer This project aims to design and test a basic calculator using Verilog, with the goal of participating in the Tiny Tapeout TT08 project to manufacture the design on a real chip and conduct further testing after the chip is delivered back. The calculator utilizes a 4x4 matrix keypad for inputting numbers and operators, and a 4digit seven-segment display to simultaneously show the input and calculated results. The calculator is designed to support addition, subtraction, multiplication, and division of both positive and negative integers and decimal numbers. Due to display limitations, the calculator handles calculations ranging from -999 to 9999 with an accuracy of 0.001. Currently, the project has successfully implemented correct handling of input numbers and operators, as well as addition, subtraction, and multiplication. Further work is needed to implement division and display results on the 4-digit seven-segment display.
