Abstract: A system and method for chip package fabrication is disclosed. The chip package includes a base re-distribution layer having an opening formed therein, an adhesive layer having a window formed therein free of adhesive material, and a die affixed to the base re-distribution layer by way of the adhesive layer, the die being aligned with the window such that only a perimeter of the die contacts the adhesive layer. A shield element is positioned between the base re-distribution layer and adhesive layer that is generally aligned with the opening formed in the base re-distribution layer and the window of the adhesive layer such that only a perimeter of the shield element is attached to the adhesive layer. The shield element is separated from the die by an air gap and is configured to be selectively removable from the adhesive layer so as to expose the front surface of the die.

Abstract: A process for producing hydrophilic growing media, preferably soil plugs, having improved properties and minimal plant toxicity. The method involves forming a resilient, integral, dimensionally stable, cohesive, homogenous mass by contacting an aggregate with a hydrophilic urethane prepolymer, glycol, plasticizer and water. The glycol acts as a coalescing agent between the prepolymer, plasticizer and water and enables flexible open cell soil plugs to be produced over a wide range of mixes. Upon curing, the prepolymer binds the aggregate material together. The mixing of the aggregate, prepolymer, glycol and water is conducted under conditions which entrain air in the media and do not adversely affect the growth of seedlings or plants.

Abstract: This invention relates to novel formulations for cohesive soil plugs used in plant nurseries. More particularly, this invention pertains to novel compositions for forming soil plugs for use in plant propagation that resist disintegration when the soil plugs containing germinating seedlings are relocated from small growth containers to larger growth containers. An adhesive soil mixture comprising: (a) growing medium; and (b) a binder containing one or more of bentonite and cellulose alkyl ether.
