The photo-active compound (PAC) in positive tone photosensitive polyimide (posi PSPI) was investigated in order to obtain good photo lithographic performance (small development loss and good photosensitivity). When the PAC structure was changed posi

We found unusual exhaust pressure dependency on photo-sensitivity of positive photo-definable polyimide (posi-PDPI) when soft baking PDPI. Higher exhaust pressure of soft baking makes higher photo-sensitivity. This tendency is reverse thing what we e

We found that positive-tone photosensitive polyimide (posi-PSPI) shows not to be compatible for electroless Ni/Au plating process which are used for Au micro bumping. In order to meet compatibility for the process, we improved chemical resistance of

The nonlinear optical anisotropy of ply(p-phenylene benzo-bisthiazole) (PBT) Langmuir-Blodgett (LB) films has been investigated by optical third-harmonic generation measurement. Polymer backbones of PBT in LB films were aligned along the dipping dire

Polyamide with side chain carboxylic acid 1a, which was the precursor polymer for polybenzothiazole, was mixed to obtain the precursor salt polymer 2a with the three armed tertiary amine in a mixture of benzene and N,N-dimethylacetamide (1:1). The so
