Abstract: PROBLEM TO BE SOLVED: To enhance mounting workability for an optical element carrier, and to make stability after mounting better by forming a base and conductor patterns from an optical-element arranged surface over to a slope to constitute an optical element carrier. SOLUTION: The light receiving surface of a photodiode 2 is connected vertically to an Si sub-board surface, and an electrode pad 13 is formed on a plane vertical to the forming surface for electrode pads 11, 14 for connecting an element, and is electrically connected through an electrode pad 12 on the slope A3. Besides, an external leading-out electrode pad 16 is formed on a surface vertical to the forming surface for the element connecting electrode pads 11, 14 similarly to the electrode pad 13, and electrically connected through a wiring pattern 15 formed on the slope A2.

Title: Repairing method for semiconductor device
Inventor: FUKUI YASUHARU
IPC: H01L21/60
Filed: 1991-04-25
Abstract: PURPOSE:To obtain a repairing method of a semiconductor device wherein the electrode of a semiconductor chip and a protruding electrode are made to face each other and connected, by alloy-bonding, which bump electrode is composed of noble metal material which is collectively formed with the conductor wiring of a wiring board having a different thermal expansion coefficient from the semiconductor chip, by a printing system realizing the reduction of bump electrode forming cost. CONSTITUTION:A semiconductor device is set on a stage. Heating gas 8 and cooling gas 9 are alternately blown against both an imperfect semiconductor chip 5 and a wiring board 1 through a glass tube 6, thereby applying heat shock. As the result, thermal stress is generated on account of the difference between the thermal expansion coefficient of the material of the imperfect semiconductor chip 5 and that of the material of the wiring board 1. Said stress is concentrically applied to the alloy bonding part of a bump electrode 3 because of the semiconductor device structure. By repeating this process, the alloy bonding strength can be decreased. When said strength becomes small, the imperfect semiconductor chip 5 is removed from the wiring board 1, a new semiconductor chip is set on the part, and reconnection is performed.
