Abstract
Abstract A sealed semiconductor unit includes an electrical component within a defined area on a semiconductor material. A cover with the dimensions of the semiconductor defined area is placed over the semiconductor material with a sealant there between. The dimensions of the cover are aligned with the dimensions of the semiconductor. The sealed unit includes electrical contacts extending from outside the sealed unit to the electrical component within the sealed unit on the semiconductor material. The sealed semiconductor unit, including the cover, the semiconductor material, and the electrical component, has an area of the semiconductor material.

Claim 1
Independent Claim
229 words
A product made by the process of sealing a first electrical component, contained within a first defined area on the surface of a first semiconductor material with cover having a second electrical component and forming a sealed unit having the area of said first semiconductor by: a. connecting to said first electrical component, electrical contacts including electrical contacts extending outside said sealed unit for the direct connection of said first electrical component to a separate electrical component outside said sealed unit; b. forming a cover having a second defined area and having the dimensions and area of said first semiconductor; c. forming said cover of a second semiconductor material; d. forming in said second defined area of said second semiconductor material a second electrical component; e. connecting to said second electrical component, second electrical contacts; f. aligning electrical contacts of said first electrical component with matching contacts of said second electrical contacts; g. applying a non-conductive sealant between said electrical contacts of said first and second set of electrical contacts and applying a conductive sealant on the contacting surfaces of said matching contacts of said first and second set of electrical contacts; h. aligning the dimensions of said second semiconductor material with the dimensions of the first semiconductor material; i. applying said second semiconductor material to said first semiconductor material in a layered relationship to form a sealed unit.
