Described encapsulation comprises that one is designated as 10 chip-carrier usually, and the latter comprises metal substrate 12.Described metal substrate preferably has the copper core 14 that is coated with chromium 16 and 18 its apparent surface.Yet, to describe as present, can use other metals, as fine copper, invar, copper-invar-copper (C-I-C) and other this type of materials.Yet, because it is very good electric conductor and has good thermal conduction characteristic so that can be used as fin that the copper of chromium plating is optimal material.Usually, described substrate 12 thickness are about 0.025 inch, although thickness can be in the scope about to 0.04 inch about 0.010 inch.Be thinner than 0.010 inch thick substrate and significantly reduced the efficient of described substrate, make encapsulation volume huge and heavy and surpass 0.040 inch thick substrate, and more significant heat radiation is not provided as fin.
Thin layer dielectric material 20 is applied on the chromium 16 on a surface of described substrate 10, and it preferably has 3.5 to 4.0 dielectric constant.Best medium is a polyimides.Described polyimides preferably sprays, and makes to apply uniform shallow layer.Yet polyimides can spin coating.Can use other media, as epoxy resin, polytetrafluoroethylene etc.; Yet, be preferably polyimides, because its easy coating, have uniform coating and can remain in substrate surface and thickness is reduced to 6 microns and do not had big defective, this is preferable thickness.Yet operable thickness is up to about 20 microns.Coating is got over Bao Yuehao, because core body is used as a floating earth plane, medium is thin more, and the efficient of described metal substrate 12 is high more.In fact, the thickness of polyimides 20 is about 6 microns, and the efficient of described substrate 12 is about 95% of the heat efficiency, and is 20 microns at the thickness of polyamide 20, and the heat efficiency is reduced to about 50%.Thereby 20 microns thickness is the maximum ga(u)ge of the medium 20 that allowed, and preferably 6 microns or thinner thickness.
In the circuit forming surface system of described medium 20, this Circuits System comprises chip anchor pad 22, connection pads 24 and circuit trace 26.Described circuit preferably forms by the photosensitive corrosion-resisting technics that utilizes known spraying depositing metal of industry and close etching technology.Usually described metal spraying is deposited to about 6 microns thickness; Yet the thickness of metal can be in the scope about to 8 microns about 4 microns.Book can cause that in 4 microns thickness Circuits System is discontinuous, can not produce microcircuit (fine circuit) characteristic and be thicker than 8 microns thickness.
