PROBLEM TO BE SOLVED: To provide a semiconductor element having a reinforced bonding pad lower structure, and its fabricating method. SOLUTION: The semiconductor element has an interlayer insulation film formed beneath a bonding pad metal layer while including a contact trench part formed into mesh shape, as a whole, by transferring a pattern 210A, where a plurality of points spaced apart at a constant interval without being coupled each other in the exposure process are arranged in mesh shape as a whole, onto a photoresist film 212 and then passing the pattern 210A through developing and etching processes. Consequently, the yield is enhanced by embodying a meshed contact trench part of fine line width impossible to be formed by current photolithographic process while improving the bonding power and the reliability of the semiconductor element.

PROBLEM TO BE SOLVED: To provide a method for forming a re-wiring bump, a semiconductor chip and mounting structure using the method. SOLUTION: The bump forming method makes the mounting of an LDI chip easy and can enlarge a bump area with the same pad pitch even if an upper portion of a bump 43 is flat in order to minimize the area of a pad 33 in the chip, and the chip and its mounting structure use the method. Thereby, a pad area at the edge of a conventional chip can be minimized, the bump 43 is formed on a flat portion inside the chip, and an electrical connection between the pad 33 and the bump 43 is attained with a re-wiring metal film.

PROBLEM TO BE SOLVED: To provide a semiconductor apparatus for imaging a solid object which is thinner than a customary apparatus and is down-sized. SOLUTION: The semiconductor apparatus for imaging a solid object includes: a lens attachment portion; semiconductor chip for imaging the solid object which converts light to a image signal; a conductive substance which is formed in a via-hole formed on a scribe line of the solid semiconductor chip for imaging and electrically connects a bonding pad formed on an upper surface of the solid semiconductor chip for imaging and a terminal formed on its lower surface; and a circuit board which electrically connects them through the terminal formed on the lower surface of the solid semiconductor chip for imaging. Additionally, the semiconductor apparatus for imaging the solid object uses a conductive line formed along the side surface of the semiconductor chip of imaging the solid object instead of the conductive substance.

PROBLEM TO BE SOLVED: To provide a more small-sized tape wiring board, and to provide a semiconductor chip package using it. SOLUTION: Input wiring 222, output wirings 223 and 224 and/or bypass wiring 225 are formed to pass through the inside of portion 226, where the semiconductor chip 241 is mounted on a base film 221. Thereby, the wiring pattern does not pass the outside of the semiconductor chip 241 along the outer contour of the base film 221, the circuit pattern is minimized, and the base film is small-sized.

SOLUTION: The semiconductor chip 210 comprises a plurality of bonding pads 211, provided with active surfaces 212, the rear surfaces of the active surfaces 212 or inactive surfaces 213 and side surfaces 215 between the active surfaces 212 and the inactive surfaces 213 while being provided on the active surfaces 212, a plurality of bump pads 216, provided on the inactive surfaces 213 so as to be corresponding to the bonding pads 211, and a plurality of connecting wires 217, provided on the inactive surfaces 213 and extended so as to be exposed in the side surfaces 215. Further, the semiconductor chip 210 comprises at least one set or more of heat dissipating units 219 formed on the inactive surfaces 213. The bump pads 216, the connecting wirings 217 and the heat dissipating units 219 are formed in wiring grooves whereby mutual communication and heat dissipation can be easily realized upon laminating the semiconductor chips.

Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor element, having a bonding pad and its manufacturing method. SOLUTION: The bonding pad has two conductive films and an intermediate layer inbetween them. The intermediate layer has a hybrid form, which is a mixture of a relatively conductive flat board part and a plug/mesh part. The plug/mesh part has a conductive part which is periodically pierced by non- conductive parts or a non-conductive part which is periodically pierced by conductive parts. The width of the conductive part or the non-conductive part in the plug/mesh part is comparatively smaller than that of the flat board part. The hybrid form keeps appropriate balance between the frat board part, where a probe pin contacts and the plug/mesh part which provides an additional path for electric current. COPYRIGHT: (C)2003,JPO
