Patent JP-H09162514-A (JP)
Title: Printed wiring board and its manufacture
Inventor: TAMAKI MASANORI
IPC: H05K3/46
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the heat cycle characteristic of a printed wiring board without sacrificing the adhesive property of the board by forming a copper alloy layer of a gradient alloy, the copper concentration of which becomes higher as going toward the lower surface of the alloy layer. SOLUTION: A copper alloy layer 7 formed on a copper-made lower layer conductor circuit 2 in a printed wiring board is made of a graded alloy, the copper concentration of which becomes higher as going toward the lower surface of the layer 7. Therefore, the adhesion between the circuit 2 and an upper-layer conductor circuit 8 having the copper alloy layer 7 can be improved without sacrificing the adhesion property of the layer 7 with an insulating resin layer. It is preferable to adjust the copper concentration so that the concentration can change within the range of 20-90atm% continuously or in stages from the upper surface side to the lower surface side of the layer 7. In addition, the thickness of the layer 7 is adjusted to 0.5-3μm.  In a method for manufacturing the printed wiring board, the bath load of a plating bath is adjusted to 0.2-1.5dm<2> /l in order to form the copper alloy layer 7 having such a copper concentration gradient.

Title: Pattern forming material and pattern forming method using the material
Inventor: UCHINO MASAICHI
IPC: G03F7/039
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To inhibit the diffusion of an acid into an unradiated part without inhibiting a catalytic reaction in an radiated part by incorporating a specified organic halide, a basic organic compound, an acid precursor and a medium whose solubility to an aqueous alkali solution varies. SOLUTION: The pattern forming material contains an organic halide which generates hydrochloric acid or hydrobromic acid when irradiated, a basic organic compound, an acid precursor which generates an acid other than the haloid acids when radiated and a medium which is not substantially decomposed by the generated haloid acid but substantially decomposed by the acid generated from the acid precursor to vary its solubility to an aqueous alkali solution. The organic halide efficiently forms the haloid acid under radiation and selectively neutralizes the basic organic compound in the radiated part. Since the haloid acid is not formed in the unradiated part and the basic organic compound in the unradiated part is not neutralized, the acid diffused from the radiated part into the unradiated part is captured and the diffusion of the acid into the unradiated part is inhibited.
