Publication number: 20230387029Abstract: A semiconductor package includes a first sub-semiconductor device, an interposer, and a second sub-semiconductor device stacked on each other, and a heat sink covering the second sub-semiconductor device. The first sub-semiconductor device includes a first substrate and a first semiconductor chip. The interposer includes a dielectric layer, a thermal conductive layer in contact with a bottom surface of the dielectric layer, a first thermal conductive pad in contact with a top surface of the dielectric layer, and thermal conductive vias penetrating the dielectric layer to connect the thermal conductive layer to the first thermal conductive pad. A bottom surface of the thermal conductive layer is adjacent to and connected to a top surface of the first semiconductor chip. The second sub-semiconductor device is disposed on the dielectric layer without overlapping the first thermal conductive pad. The heat sink further covers the first thermal conductive pad to be connected thereto.Type: ApplicationFiled: April 28, 2023Publication date: November 30, 2023Applicant: Samsung Electronics Co., Ltd.Inventors: JIWON SHIN, DONGUK KWON, KWANG BOK WOO, MINSEUNG JI

Patent number: 10008642Abstract: A semiconductor light emitting device may include a semiconductor light emitting diode (LED) chip, a light-transmitting film on the LED chip, and a light-transmitting bonding layer between the light-transmitting film and the semiconductor LED chip. At least one of the light-transmitting film and the light-transmitting bonding layer may include a wavelength conversion material configured to convert light emitted by the semiconductor LED chip into light having a wavelength different from a wavelength of the emitted light. The light-transmitting bonding layer may have a lateral inclined region extending to the lateral surface to form an inclined surface. The semiconductor light emitting device may further include a reflective packaging portion surrounding the light-transmitting bonding layer, covering the first surface such that an electrode of the LED chip is at least partially exposed. The reflective packaging portion may include a reflective material.Type: GrantFiled: November 30, 2016Date of Patent: June 26, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jong Wan Seo, Jin Ha Kim, Kwang Bok Woo, Dong Hoon Lee, Won Joon Lee, Sun Hwan Hwang
