Description
Technical field
The invention relates to a kind of semiconductor package part, particularly about a kind of card-typed circuit module that is used to encapsulate storage chip, for example multimedia card (Multi-Media Card, MMC).
Background technology
Multimedia card (Multi-Media Card, MMC) be meant a kind of flash memory circuit module of high power capacity, this circuit module can be coupled to electronic information platform, for example PC, personal digital assistant (Personal Digital Assistant, PDA), digital camera, multimedia browser, can store various digital multimedia datas, for example digital photo data, video signal data or voice data.At present, the specification of multimedia card meets multimedia card alliance (Multimediacard Association, MMCA) standard of being formulated basically.
Multimedia card (Multi-Media Card, MMC) packaging part is a kind of Small Scale Integration (Integrated Circuit), have storage chip (Memory Chip) and/or control chip (Controller Chip), to store and to handle multimedia messagess such as relevant digital picture and image.Wherein, this storage chip and/or control chip carry and are connected to chip carrier (Chip Carrier), on substrate (Substrate) or lead frame (Lead frame), make chip be electrically connected to external device so that operation and performance chip functions.Existing structure can be referring to United States Patent (USP) the 5th, 677, No. 524 " CHIPCARD AND A METHOD FOR PRODUCING IT ", United States Patent (USP) the 6th, 040, No. 622 " SEMICONDUCTOR PACKAGE USING TERMINALS FORMEDON A CONDUCTIVE LAYER OF A CIRCUIT BOARD ", and Japan Patent 62-239554 number " IC CARD TYPEEP-ROM STRUTURE ".
Figure 1A to Fig. 1 C is a kind of manufacturing process of existing multimedia card.This processing procedure is to be used for making the multimedia card that length is of a size of 32 * 24 * 1.4mm of standard.
At first see also Figure 1A, the initial step of this existing processing procedure is that prefabricated a series of substrates 10 mark off at least one chip placing district 11 and a plurality of passive components settlement 12 in advance on each substrate 10, and a plurality of electric connection pads 13 are set; These electric connection pads 13 are from the straight-through back side, the front of substrate 10, as the external electric connection point of the multimedia card of finishing at last.Because this processing procedure is to be used for making the multimedia card that length is of a size of 32 * 24 * 1.4mm of standard, so the length and width size of aforesaid substrate 10 is to cooperate this standard size to be designed to 30.25 * 21.25mm.
As Figure 1B, bonding resistor, capacitor or inductor 30 on this passive component settlement 12 then, are settled chip program, settle at least one semiconductor chip 20 in the chip placing district 11 on the substrate 10; Adopt for example bonding wire (Wire Bond) technology again, apply one group of for example bonding wire 40 of gold thread, chip 20 is electrically coupled to electric connection pad 13 on the substrate 10; Then carry out the packing colloid processing procedure, on substrate 10, form a packing colloid 50, coat chip 20 and the bonding wire 40 settled on the substrate 10.
For another example shown in Fig. 1 C, on substrate 10, cover a shell body 60 that is coated with adhesive-layer 51, with whole base plate 10 and on packing colloid 50 embed and adhere in these shell body 60 formed spatial accommodations 61, promptly finish the processing procedure of multimedia card.Fig. 1 D is the face upwarding assumption diagram after display base plate 10 is embedded in shell body 60.
Because above-mentioned processing procedure is to be used to make the multimedia card that length and width is of a size of 32 * 24mm, therefore the length and width size of above-mentioned shell body 60 is 32 * 24mm, and the length and width size of spatial accommodation 61 wherein cooperates the length and width of substrate 10 to be of a size of 30.25 * 21.25mm.
The shortcoming of above-mentioned processing procedure is that substrate 10 length and width that adopted are oversize, far surpass the length and width size of chip 20, so cost of manufacture is very high, and the monolithic cost does not meet the cost economic benefit up to NT$20.0, has limited its commercialization yet; In addition, the shell body 60 of existing specification, for example accommodation space shown in Fig. 1 C 61, also form the waste on the chip configuration space, do not meet the semiconductor development trend of current integrated (Integration), significantly reduced the operation usefulness of multimedia card, have much room for improvement.
