Abstract
Abstract A molded electronic circuit package is described to which stabilizing tape can be attached using automatic or semi-automatic means. The stabilizing tape stabilizes the assembly for further processing operations such as dicing or attachment to a higher level package. The assembly comprises a substrate to which devices are attached. Molded caps are formed over the devices. Molded tape supports are formed at the same time as the molded caps and are located adjacent to opposite sides of the molded cap. The molded tape supports have the same height as the molded cap. The stabilizing tape can then be attached to the tops of the molded tape supports and the molded caps using automatic or semi-automatic means.

Claim 8
Independent Claim
270 words
A method of forming a molded package, comprising the steps of: providing a substrate having a first surface, a second surface, and one or more devices attached to said first surface of said substrate; providing an upper mold section, wherein said upper mold section has one or more cavities for molded caps, one or more cavities for molded tape supports, one or more mold runner cavities, and one or more cavities for an uncured molding compound; providing a lower mold section, wherein said lower mold section has a substrate cavity for holding and positioning said substrate; placing said substrate into said substrate cavity in said lower mold section; forcing uncured molding compound into said cavities for molded caps and said cavities for tape supports; curing said molding compound, thereby forming one or more molded caps and one or more molded tape supports on said first surface of said substrate, wherein each of said molded caps has a first number of sides and a top, said top of each of said molded caps is a first distance above said first surface of said substrate, each of said molded caps covers one or more of said devices, each of said molded tape supports has a top, there are two of said molded tape supports for each of said molded caps located adjacent to opposite sides of said molded caps, and said top of each of said molded tape supports is said first height above said first surface of said substrate; and removing said upper mold section and said lower mold section from said substrate, said molded caps and said molded tape supports.
Claim 9
Independent Claim
270 words
A method of forming a molded package, comprising the steps of: providing a substrate having a first surface, a second surface, and one or more devices attached to said first surface of said substrate; providing an upper mold section, wherein said upper mold section has one or more cavities for molded caps, one or more cavities for molded tape supports, one or more mold runner cavities, and one or more cavities for an uncured molding compound; providing a lower mold section, wherein said lower mold section has a substrate cavity for holding and positioning said substrate; placing said substrate into said substrate cavity in said lower mold section; forcing uncured molding compound into said cavities for molded caps and said cavities for tape supports; curing said molding compound, thereby forming one or more molded caps and one or more molded tape supports on said first surface of said substrate, wherein each of said molded caps has a first number of sides and a top, said top of each of said molded caps is a first distance above said first surface of said substrate, each of said molded caps covers one or more of said devices, each of said molded tape supports has a top, there are two of said molded tape supports for each of said molded caps located adjacent to opposite sides of said molded caps, and said top of each of said molded tape supports is said first height above said first surface of said substrate; and removing said upper mold section and said lower mold section from said substrate, said molded caps and said molded tape supports.
