With a total of 4 patents to his name, his work has had a substantial impact on the industry.

Latest Patents

Meinert's latest patents include innovative mechanisms for photo resist film application. One of his notable inventions is a dry film photoresist laminator that features a punch and die assembly. This assembly punches a rolled sheet of dry film photoresist material into photoresist decals. The decals are then bonded to a tacky transport tape, which carries them to a polyolefin peeler assembly. This assembly rolls a high tack tape along the polyolefin layer of the decal, effectively peeling it from the decal. The decal is then advanced by a laminating assembly onto a heated wafer, bonding the exposed photoresist material to the wafer. The bonded wafer and decal are subsequently removed from the transport tape.

Another significant patent by Meinert is a dry film resist transport and lamination system for semiconductor wafers. This system also utilizes a punch and die assembly to create photoresist decals from a rolled sheet of dry film photoresist material. The process involves bonding the decals to a tacky transport tape and advancing them through various process steps, ultimately resulting in a wafer laminated with dry film photoresist material.
