An inorganic shell is ball-shaped and hollow, and includes silica and crystalline inorganic powder sintered together. A resin composition has the inorganic shells and the resin composition has certain dieletric characteristics. A method for making the inorganic shell is also provided.

Inorganic shell, resin composition, and method for making inorganic shell

A resin composition comprises a styrene-butadiene-styrene block copolymer. The resin composition further comprises a plurality of hydrated inorganic substances and/or a plurality of microcapsule particles dispersed in the styrene-butadiene-styrene block copolymer. The hydrated inorganic substances dehydration to form anhydrous inorganic substances at a dehydration temperature greater than 250 degrees Celsius. Each microcapsule particle comprises a housing and an embedded object encapsulated in the housing. The embedded object will largely volatilize from the housing at an escaping temperature greater than 250 degrees Celsius. A removable adhesive layer, an IC substrate, and an IC packaging process are also provided.
