Publication number: 20170243847Abstract: To provide a technique capable of reducing the chip size of a semiconductor chip and particularly, a technique capable of reducing the chip size of a semiconductor chip in the form of a rectangle that constitutes an LCD driver by devising a layout arrangement in a short-side direction. In a semiconductor chip that constitutes an LCD driver, input protection circuits are arranged in a lower layer of part of a plurality of input bump electrodes and on the other hand, in a lower layer of the other part of the input bump electrodes, the input protection circuits are not arranged but SRAMs (internal circuits) are arranged.Type: ApplicationFiled: May 5, 2017Publication date: August 24, 2017Inventors: SHINYA SUZUKI, KIICHI MAKUTA

Publication number: 20170243848Abstract: Solder-bumped semiconductor substrates (e.g., semiconductor wafers) and methods for forming solder bumped semiconductor substrates are provided, in which solder bumps are formed on a semiconductor substrate using preformed solder balls having different compositions and/or sizes. Two or more solder balls masks are successively utilized to place different types of preformed solder balls (differing in composition and/or size) into corresponding cavities of a solder ball fixture, and thereby form an array of different types of preformed solder balls arranged in the solder ball fixture. The array of preformed solder balls in the solder ball fixture are then transferred to corresponding contact pads of a semiconductor substrate (e.g., semiconductor wafer) using a single solder reflow process. This process allows different types of preformed solder bumps to be bonded to a semiconductor substrate at the same time using a single solder reflow process.Type: ApplicationFiled: May 10, 2017Publication date: August 24, 2017Inventor: Jae-Woong Nah
