Abstract: 본 발명의 반도체용 리드 프레임은 리드 프레임의 도금시 도금액이 흘러내리는 브리드(breed) 불량을 방지하고, 인너리드를 통해 반도체 집적소자로 습기가 침투되지 않도록 하는 것으로서 종래의 리드 프레임은 인너리드(5)의 단부만 패들(3)을 향하도록 절곡한 일자형으로 형성하였으므로 인너리드(5)를 통해 습기가 쉽게 침투하여 제조된 집적소자의 불량을 발생시켰으며, 또한 도금공정시 도금틀의 장기간 사용으로 인하여 리드 프레임의  상하면의 밀착력이 저하될 경우에 도금액이 인너리드(5)를 타고 흘러서 도금영역(6)을 벗어나게 되는 브리드 불량이 발생하였으며, 이 브리드 불량으로 인하여 볼드 공정시 수지와 리드 프레임간의 접착력이 저하되었다. 
     본 발명은 리드 프레임의 인너리드의 좌우 양측에 습기 차단홈을 형성하여 습기가 인너리드를 통해 침투되지 않도록 하고, 인너리드의 상면에는 도금액 차단홈을 형성하여 도금액의 흐름을 차단함으로써 습기의 침투로 인한 집적소자의 불량을 방지하고, 브리드 불량을 방지하여 수지와 리드 프레임이 견고하게 접착되도록 할 수 있다.

Title: A method and apparatus for coding video data
Inventor: JOEL SOLE ROJALS
Filed: 2016-01-06
Abstract: In palette-based coding, a video coder may form a so-called “palette” as a table of colors representing the video data of a given block. The video coder may code index values for one or more pixels values of a current block of video data, where the index values indicate entries in the palette that represent the pixel values of the current block (310). According to the techniques, a video coder determines one or more palette entries in a predictive palette that are copied to the current palette (302), and a number of new palette entries not in the predictive palette that are included in the current palette (304). The video coder calculates a size of the current palette equal to the sum of the number of the copied palette entries and the number of the new palette entries (306), and generates the current palette including the copied palette entries and the new palette entries (308).
