摘要:
A chemically amplified positive resist dry film to be formed on a support film contains 5-40 wt% of a component having a boiling point of 55-250°C under atmospheric pressure. The resist dry film having flexibility and dimensional stability can be prepared through simple steps. The resist dry film can be efficiently and briefly laid on an article and processed to form a pattern.

The present invention is a semiconductor apparatus including a semiconductor device, an on-semiconductor-device metal pad and a metal interconnect each electrically connected to the semiconductor device, a through electrode and a solder bump each electrically connected to the metal interconnect, a first insulating layer on which the semiconductor device is placed, a second insulating layer formed on the semiconductor device, a third insulating layer formed on the second insulating layer, wherein the metal interconnect is electrically connected to the semiconductor device via the on-semiconductor-device metal pad at an upper surface of the second insulating layer, and the metal interconnect penetrates the second insulating layer from its upper surface and is electrically connected to the through electrode at an lower surface of the second insulating layer. This semiconductor apparatus can be easily placed on a circuit board and stacked, and can reduce its warpage even with dense metal interconnects.
摘要:
A photosensitive resin composition comprising a polymer containing a silphenylene skeleton and a fluorene skeleton and having a crosslinkable site in the molecule, a phenol compound having a Mw of 300-10,000, a photoacid generator, and a benzotriazole or imidazole compound has improved film properties. Even from a thick film, a fine size pattern can be formed.
