嵌入式微接触元件及其制造方法 Embedded micro-contact device and manufacturing method

技术领域 Technical Field

[0001] 本发明是与微接触元件有关,更详而言之是指一种嵌入式微接触元件及其制造方法。 [0001] The present invention is concerned with micro-contact element, it is more detailed in terms of device and manufacturing method refers to an embedded micro-contact.

背景技术 Background

[0002] 在测试高密度或高速的电气装置如LSI或VLSI电路时,必须使用具有大量微接触元件探针的探针卡Probe Card,以通过由该微接触元件为一具有挠性且可提供电性连接的导电体特性,作为与待测试物间电气导通的元件,如作为LSI及VLSI晶片、半导体晶圆、晶片预烧、封装的半导体装置及印刷电路板的测试接触元件之用。 [0002] When the electrical device to test high-density or high-speed circuit such as LSI or VLSI, you must contact element having a large number of micro probe card probe Probe Card, through the micro-contact element is made of a flexible and can provide a electrically conductive properties of the connection, as the object to be tested between the electrically conductive elements, such as LSI and VLSI chips, semiconductor wafers, wafer burn-in, with a test contact element of the packaged semiconductor devices and printed circuit boards. 当然,微接触元件,亦可用以作为IC封装的IC引线之用。 Of course, the micro-contact element can also be used as an IC package IC lead purposes. 但,为便于后续的说明,其微接触元件主要是以作为探针卡的探针加以叙述。 However, for ease of subsequent description, which micro-contact member mainly used as a probe of the probe card be described.

[0003] —般微接触元件因应其需求而有不同的态样,其中有一种为悬梁式微接触元件,悬梁式微接触元件由于具有较高的弹性,可容许与外物接触而产生偏移时仍能保持接通的状态。 [0003] - as micro-contact element in response to their needs and have a different kind of state, in which there is a decline of cantilever contact elements, cantilever micro contact element due to the high flexibility and an offset allowable contact with foreign objects remain to maintain the ON state.

[0004] 以探针而言,如美国专利第US6268015号的专利案,如图1所示,其是通过由微机电技术以沉积金属的方式堆层出探针的结构,或分别以沉积金属方式将各一单元制出后再以接合方式加以组装;接合组装制程的精度较光刻制程差,多次的接合将因累积数次对位误差造成针尖1的定位偏差放大或悬臂梁2与支柱3的接合点误差,进而造成针尖探测位置不佳与探针性能一致性降低等缺点。 [0004] In terms of the probe, as described in U.S. Patent No. Patent No. US6268015 case shown in Figure 1, which is made by MEMS technology way to deposit metal stack structure of the probe, or respectively to deposit metal Each unit prepared a way out and then assembled to engage manner; engaging assembly process accuracy than the lithography poor, many of engagement will be several times due to the accumulation of bit error caused by an enlarged positional deviation tip or cantilever 2 Pillar 3 junction error, thus resulting in poor detection of the position of the probe tip and decreased consistency of performance shortcomings.

[0005] 另有如美国公开第US20010012739号的专利案,其同样是通过由微机电技术以沉积金属方式制作出探针的结构,且其针尖是以焊接方式接合,而其支柱(即针底)是以打线方式在外部电镀金属强化支柱的结构,其以打线方式制作支柱不仅量产速度相当的缓慢,且制程繁复,需精确的精度加以控制使之制造困难。 [0005] Another such as US Patent Publication No. US20010012739 case, which is also by the MEMS technology to deposit metal manner, a structure of the probe, and the welding tip is engaged, and its pillars (ie pin end) is a hit-line in the outer plating metal reinforcing structure pillar, which to hit line production pillar not only the production speed is quite slow and complicated process required precise accuracy to make it make it difficult to control.

[0006] 再如美国专利第US6399900号的专利案,亦是由微机电技术以沉积方式制作探针结构,其针尖以焊接方式与针体一端接合,针体的另一端则与基版的表面贴附接合,其稳固性较差,于反覆操作下可能因材料疲劳而产生与基版脱离的情事,且针尖需以相当精准方式焊接,如有焊接位置上的偏移将导致针尖接触力的不均匀。 [0006] Another example is US Patent No. US6399900 patent case number, also by way of MEMS technology for the production of probes deposited structure by welding tip engagement with the needle end, the other end of the needle and the surface of the base plate attaching engagement, its stability is poor, probably due to material fatigue arising from the base version of the circumstances under repeated operations, and the need to tip quite accurate way welding, welding position if offset will cause the tip contact force uneven.

[0007] 再者,如美国专利第US6414501号专利案,其是通过由微机电技术以蚀刻硅基材的方式加以制造探针,并于探针的外部镀上导电薄膜后再与基版接合;但,探针部分大部分由硅基材制成,导电薄膜的厚度相当的薄,仅涂布硅基材所制成的探针结构表面,因此其电流的耐受性不高无法符合高流量的需求,且由于探针的挠性结构主要以单晶硅为其材料,容易脆裂而无法修复。 [0007] Furthermore, as described in U.S. Patent No. US6414501 patent case, which is by the MEMS technology to etch silicon substrate manner of manufacturing the probe and the probe of the external plating on the conductive film and the base version before joining ; however, most part of the probe is made of a silicon substrate, corresponding to the thickness of the conductive thin film, only the structure of the surface of a substrate made of a silicon probe coated, so the resistance is not high current can not meet the high traffic demand, and because of the flexible structure of the probe mainly for single-crystal silicon material, easy to rattle and can not be repaired.

[0008] 其次,以美国专利第US4961052、 US5172050、 US5723894号的专利案而言,其皆是以直接蚀刻硅基版的方式,以单晶硅材质制作出探针,再于由硅基版所制成的探针外镀上一导电薄膜以提供电气连接;但,由于导电薄膜无法耐受高流量的需求,且探针主要以单晶硅为其材料,有容易脆裂无法修复的缺点。 [0008] Secondly, the United States Patent No. US4961052, US5172050, US5723894 number of patent cases, its all based on direct etching the silicon version of the way to produce single crystal silicon material probe, and then at the silicon-based version of the The probe is made of a conductive thin film on the outer coating to provide electrical connections; however, since the conductive film can not tolerate high traffic demand, mainly in the single-crystal silicon and the probe for material, there is likely to rattle the shortcomings can not be repaired.

3[0009] 另外,以美国专利第US5974662号专利案,是一种平面调整机构,其是可于组装时利用若干平面的微调使之进行水平的调整,且为使得于调整时所有的电路仍能保持良好的接触状态,必须在探针与电子基版间增加若干层的弹性探针;但,由于此结构过于复杂且线路的传输路径较长并不适用于高频的传输。 3 [0009] In addition, US Patent No. US5974662 patent case, a plane adjusting mechanism, which is available to fine-tune several planes at the time of assembly so as to adjust the level, and so on all the circuits are still adjustments can maintain a good contact state, the probe must be increased several elastic layers between the probe and the electronic version of the group; however, since this structure is too complicated and long lines of the transmission path is not applicable to high-frequency transmission.
