摘要:
A method for manufacturing a tape wiring board in accordance with the present invention may employ an imprinting process in forming a wiring pattern thereby reducing the number of processes for manufacturing a tape wiring board and allowing the manufacturing process to proceed in a single production line. Therefore, the manufacturing time and cost may be reduced. A profile of the wiring pattern may be determined by the shape of an impression pattern of a mold. This may establish the top width of inner and outer leads and incorporate fine pad pitch. Although ILB and OLB process may use an NCP, connection reliability may be established due to the soft and elastic wiring pattern.

An image sensor package, a method of manufacturing the same, and an image sensor module including the image sensor package are provided. In the image sensor package, an image sensor chip is installed onto a depression of a transmissive substrate. An adhesive bonds the image sensor chip to the transmissive substrate and seals an Active Pixel Sensor (APS) on the image sensor chip, protecting it from fine particle contamination. An IR cutting film is disposed on the transmissive substrate to minimize the height of the image sensor package. The image sensor package is electrically connected to external connection pads in the depression. Consequently, the image sensor package has a minimum height, is not susceptible to particle contamination, and does not require expensive alignment processes during manufacturing.

摘要:
Example embodiments of the present invention relate to an alloy solder and a semiconductor device using the alloy solder. Other example embodiments relate to an alloy solder capable of increasing reliability of a junction between a semiconductor chip and a substrate. According to still other example embodiments of the present invention, there may be a tin-bismuth (Sn—Bi) family alloy solder between a semiconductor chip and a substrate, and a semiconductor device using the alloy solder. The semiconductor device may include a semiconductor chip formed with a plurality of gold (Au) bumps, a substrate having metal wirings connected to the gold (Au) bumps, and a junction including a tin-bismuth (Sn—Bi) family alloy solder interposed between and connecting the gold (Au) bump and the metal wiring.The formation of a relatively large amount of AuSn4 intermetallic compound may be inhibited in the junction because gold (Au) may not easily diffuse into a tin-bismuth (Sn—Bi) family alloy solder of a liquid state during a reflow process for connecting the semiconductor chip and substrate. Therefore, most of the junction may be retained as the tin-bismuth (Sn—Bi) family alloy solder.
摘要:
A circuit film having film bumps is provided for a film package. An IC chip is mechanically joined and electrically coupled to the circuit film through the film bumps instead of conventional chip bumps. In a fabrication method, a base film is partially etched by a laser to create an etched area that defines raised portion relatively raised from the etched area. Then a circuit pattern is selectively formed on the base film, partly running over the raised portions. The raised portion and the overlying circuit pattern constitute the film bumps having a height not greater than the height of the circuit film.
