Latest Patents

Brewer's most notable patent is the "Sectional Porous Carrier Forming a Temporary Impervious Support." This invention involves compositions and designs for a sectional porous carrier utilized in processing microelectronics. The carrier allows thin device substrates to be securely affixed with adhesive, resulting in an impervious bonded stack that withstands thermal and chemical challenges during processing. Notably, the design facilitates easy handling by substrate handling vacuum robots.

A key feature of this invention is the rapid removal, or debonding, of substrates in batch operations. This is achieved through the directional penetration of selective liquids into the carrier's porous regions, effectively releasing the carrier from the device wafer without causing any harm. The sectional porous nature of the carrier supports passive diffusion of chemical liquids, a method that proves to be more effective than mechanical, thermal, or radiative alternatives. Brewer's innovation importantly reduces costs and increases throughput in manufacturing environments for semiconductor and microelectronic devices. The preferred designs involve the use of porous metal forms, including laminates, along with surface treatments to optimize the support mechanism during device manufacturing.
