Abstract
An encapsulated microelectronic device (100) including a base (101) and a semiconductor device (305) having a top and a bottom. The bottom is attached to the base (101). The semiconductor device (105) has a thickness in the range from one-fourth to three-fourths of a millimeter and has a bottom metallization consisting of aluminum (407)/chromium (405)/nickel (403)/gold (401). The semiconductor device (305) has a contact (115) attached to the top. The encapsulated microelectronic device (100) has a molded top (120) surrounding the semiconductor device (305). The molded top (120) is made from low stress molding material.
