Patent number: 10684118Abstract: An apparatus for determining an orientation of a die mounted on a tape includes an imaging device, a light source and a conveying mechanism. The die is at least partially translucent and includes at least one orientation feature indicative of the orientation of the die. In use, the conveying mechanism conveys the tape to position the die at an inspection position between the imaging device and the light source. The light source projects light to the imaging device and the imaging device captures an image. The projected light from the light source passing through the die is obstructed by the at least one orientation feature of the die to cause the captured image to include an image of the at least one orientation feature, whereby the orientation of the die may be determined.Type: GrantFiled: April 9, 2019Date of Patent: June 16, 2020Assignee: ASM TECHNOLOGY SINGAPORE PTE LTDInventors: Kai Siu Lam, Chi Leung Mok, Nim Tak Wong, Ka Yee Mak

Patent number: 10288979Abstract: The present disclosure describes the design and fabrication of a Terahertz (THz) beam steering device and a multifunctional patternless flat lens using electro-optic tunable fishnet materials (TFMM) to create a portable THz imaging system. The THz beam steering device and multifunctional patternless flat lens utilize a tunable resonant frequency of TFMM (with a negative refraction index) to achieve a maximum beam steering angle (field of view) and beam modulation. The portable THz scanning system is made by combining the TFMM beam steering device with a pair of continuous wave (CW) photomixer modules powered by two tunable CW lasers with built-in optical isolators, a fiber-optic beam combination and a multifunctional flat lens.Type: GrantFiled: December 12, 2017Date of Patent: May 14, 2019Assignee: National Tsinghua UniversityInventors: Wei-Chih Wang, Chi-Leung Tsui, Da-Jeng Yao
