Publication number: 20240120262Abstract: An electronic device includes a substrate with a conductive structure and a substrate encapsulant. The conductive structure has a lead with a lead via and a lead protrusion. The lead via can include via lateral sides defined by first concave portions and the lead protrusion can include protrusion lateral sides defined by second concave portions. The substrate encapsulant covers the first concave portions at a first side of the substrate but not the second concave portions so that the lead protrusion protrudes from the substrate encapsulant at a second side of the substrate. An electronic component can be adjacent to the first side of the substrate and electrically coupled to the conductive structure. A body encapsulant encapsulates portions of the electronic component and the substrate. The lead can further include a lead trace at the second side of the substrate.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Applicant: Amkor Technology Singapore Holding Pte. Ltd.Inventors: Hyeong Il JEON, Gi Jeong KIM, Yong Ho SON, Byong Jin KIM, Jae Min BAE, Seung Woo LEE

Publication number: 20240096725Abstract: In one example, an electronic device includes an embedded module, which includes a module substrate and module components coupled to the module substrate. A device substrate is coupled to the first module substrate. Device terminals are coupled to the module components and a device encapsulant structure encapsulates the embedded module, the device substrate, and the device terminals. A portion of the device substrate is exposed from the device encapsulant structure and portions of the device terminals are exposed from the device encapsulant structure. Other examples and related methods are also disclosed herein.Type: ApplicationFiled: August 18, 2023Publication date: March 21, 2024Applicant: Amkor Technology Singapore Holding Pte. Ltd.Inventors: Dae Young PARK, Byong Jin KIM, Gi Jeong KIM, Hyeong Il JEON, Kwang Soo SANG, Jin Young KHIM

Patent number: 11123703Abstract: Apparatus for producing fine particles having a particle formation mechanism and a particle-outlet micro-channel may include a unit-structure including first and second portions adjacent to each other; and a first inlet defined in the first portion at a first height. A continuous phase solution is injected into the first inlet; and a second inlet is defined in the first portion at a second height different from the second height. A dispersed phase solution is injected into the second inlet. A merging volume is defined in the second portion and is defined at third height equal to either the first height and the second height, or has a value therebetween. The continuous phase solution and the dispersed phase solution are merged in the merging volume, wherein fine particles are formed. A first micro-channel and a second micro-channel branching from the merging volume communicates with the first inlet and the second inlet, respectively.Type: GrantFiled: March 22, 2017Date of Patent: September 21, 2021Assignee: ENPARTICLE CO.,LTD.Inventors: Jeung Sang Go, Hyo Chang Cho, Hyeong Jin Jeon, Moon Jeong Kim
