摘要:
A structure (40) for holding an integrated circuit die (38) during packaging includes a support substrate (42), a release film (44) attached to the substrate (42), and a swelling agent (60). A method (34) of packaging the die (38) includes placing the die (38) on the substrate (42) with its active surface (52) and bond pads (54) in contact with the film (44). The agent (60) is applied over an adhesive coating (50) of the film (44). The agent (60) causes the adhesive (50) to swell into contact with the bond pads (54) and/or to form fillets (64) of adhesive (50) about the die (38). The die (38) is encapsulated in a molding material (72) and released from the substrate (42) as a panel (74) of dies (38). Swelling of the adhesive (50) about the bond pads (54) prevents the molding material (72) from bleeding onto the bond pads (54).
摘要(中):
用于在封装期间保持集成电路管芯(38)的结构(40)包括支撑基板(42),附着在基板(42)上的脱模膜(44)和溶胀剂(60)。 封装模具(38)的方法(34)包括将模具(38)放置在基板(42)上,其活性表面(52)和与薄膜(44)接触的粘结垫(54)。 将试剂(60)施加在薄膜(44)的粘合剂涂层(50)上。 试剂(60)使粘合剂(50)膨胀成与粘合垫(54)接触和/或形成围绕模具(38)的粘合剂(50)的圆角(64)。 模具(38)被封装在模制材料(72)中并且作为模具(38)的面板(74)从基板(42)释放。 粘合剂(50)围绕接合焊盘(54)的膨胀防止模制材料(72)渗透到接合焊盘(54)上。
