本發(fa)明涉(she)及顯示技術(shu)領域,尤其涉(she)及一種(zhong)微(wei)轉印方法。
背景技術:
微發光二(er)極管(microled)是一(yi)種(zhong)尺寸(cun)在幾微米到幾百(bai)微米之間的(de)(de)器(qi)(qi)(qi)(qi)件,由于(yu)其較普通led的(de)(de)尺寸(cun)要小很多(duo),從而使得單一(yi)的(de)(de)led作為像(xiang)(xiang)素(su)(pixel)用于(yu)顯(xian)(xian)(xian)(xian)示(shi)(shi)成(cheng)為可能,microled顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)便是一(yi)種(zhong)以高密(mi)度的(de)(de)microled陣列作為顯(xian)(xian)(xian)(xian)示(shi)(shi)像(xiang)(xiang)素(su)陣列來實現(xian)圖(tu)像(xiang)(xiang)顯(xian)(xian)(xian)(xian)示(shi)(shi)的(de)(de)顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi),同大尺寸(cun)的(de)(de)戶外led顯(xian)(xian)(xian)(xian)示(shi)(shi)屏一(yi)樣,每一(yi)個像(xiang)(xiang)素(su)可定(ding)址、單獨驅動點亮(liang),可以看成(cheng)是戶外led顯(xian)(xian)(xian)(xian)示(shi)(shi)屏的(de)(de)縮小版,將像(xiang)(xiang)素(su)點距離從毫米級降低(di)至(zhi)微米級,microled顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)和有機(ji)發光二(er)極管(organiclight-emittingdiode,oled)顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)一(yi)樣屬于(yu)自發光顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi),但microled顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)相比于(yu)oled顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)還具有材(cai)料(liao)穩定(ding)性更(geng)好、壽命更(geng)長(chang)、無影像(xiang)(xiang)烙印等優(you)點,被認(ren)為是oled顯(xian)(xian)(xian)(xian)示(shi)(shi)器(qi)(qi)(qi)(qi)的(de)(de)最大競爭(zheng)對(dui)手。
由于晶格匹配的(de)(de)(de)(de)(de)原(yuan)因,microled器件必須先在(zai)藍寶石類的(de)(de)(de)(de)(de)供(gong)給(gei)基(ji)(ji)板(ban)(ban)上通過(guo)分子束外延(yan)的(de)(de)(de)(de)(de)方法生長出來,隨(sui)后(hou)通過(guo)激光剝離(laserlift-off,llo)技(ji)術(shu)將(jiang)微(wei)發光二(er)(er)極管(guan)裸芯片(barechip)從供(gong)給(gei)基(ji)(ji)板(ban)(ban)上分離開,然后(hou)通過(guo)微(wei)轉(zhuan)印(yin)(microtransferprint)技(ji)術(shu)將(jiang)其轉(zhuan)移到(dao)已經預(yu)先制備完(wan)成(cheng)電(dian)路圖(tu)(tu)案的(de)(de)(de)(de)(de)接(jie)受(shou)基(ji)(ji)板(ban)(ban)上,形成(cheng)microled陣列,進而做成(cheng)microled顯示面板(ban)(ban)。其中,微(wei)轉(zhuan)印(yin)microled陣列的(de)(de)(de)(de)(de)基(ji)(ji)本原(yuan)理大致為:使(shi)用具(ju)有圖(tu)(tu)案化的(de)(de)(de)(de)(de)傳送(song)(song)(song)頭(tou)(transfer),例如具(ju)有凸(tu)起(qi)結構的(de)(de)(de)(de)(de)聚(ju)二(er)(er)甲基(ji)(ji)硅氧烷(polydimethylsiloxane,pdms)類傳送(song)(song)(song)頭(tou),通過(guo)具(ju)有粘性(xing)的(de)(de)(de)(de)(de)pdms傳送(song)(song)(song)層(transferlayer)將(jiang)microledbarechip從供(gong)給(gei)基(ji)(ji)板(ban)(ban)吸(xi)附起(qi)來,然后(hou)將(jiang)pdms傳送(song)(song)(song)頭(tou)與接(jie)受(shou)基(ji)(ji)板(ban)(ban)進行(xing)對位,隨(sui)后(hou)將(jiang)pdms傳送(song)(song)(song)頭(tou)所吸(xi)附的(de)(de)(de)(de)(de)microledbarechip貼附到(dao)接(jie)受(shou)基(ji)(ji)板(ban)(ban)預(yu)設的(de)(de)(de)(de)(de)位置上,再將(jiang)pdms傳送(song)(song)(song)頭(tou)從接(jie)受(shou)基(ji)(ji)板(ban)(ban)上剝離,即可完(wan)成(cheng)microledbarechip的(de)(de)(de)(de)(de)轉(zhuan)移,形成(cheng)microled陣列。
目前,來自愛爾蘭的(de)(de)x-celeprint、美國德(de)州大(da)學(xue)等(deng)都曾(ceng)發表過(guo)有關microled顯(xian)示(shi)器的(de)(de)研究成果(guo)。蘋果(guo)公司(si)于2014年正式收(shou)購(gou)具有microled技(ji)術(shu)的(de)(de)luxvue后(hou),引發業界開始(shi)關注于microled的(de)(de)技(ji)術(shu)優勢,luxvue與x-celeprint所使用的(de)(de)微(wei)轉移技(ji)術(shu)差別較大(da),x-celeprint主要利(li)用pdms等(deng)膜層結構的(de)(de)吸(xi)附(fu)(fu)力進行轉移動作,而luxvue通(tong)過(guo)在傳送頭的(de)(de)凸起上通(tong)電(dian),利(li)用靜(jing)電(dian)力來吸(xi)附(fu)(fu)microled等(deng)器件。
不論采用何(he)種方式(shi)進(jin)行吸附的(de)(de)transfer,transfer的(de)(de)轉(zhuan)移(yi)良(liang)率(lv)和(he)(he)速度(du)都(dou)是技術的(de)(de)關鍵點,在現(xian)有(you)微(wei)轉(zhuan)印方法的(de)(de)transfer移(yi)動過(guo)程(cheng)中(zhong),transfer從提供零部(bu)件的(de)(de)襯底(di)上(shang)吸附起(qi)例如led、集成電路芯片(ic)等微(wei)米尺寸(cun)的(de)(de)零部(bu)件時,其實際是克服地(di)球重(zhong)(zhong)力(li)和(he)(he)襯底(di)的(de)(de)吸附力(li),而在移(yi)動和(he)(he)轉(zhuan)移(yi)的(de)(de)過(guo)程(cheng)中(zhong),也時刻受到地(di)球重(zhong)(zhong)力(li)影響;假設transfer移(yi)動速度(du)較快,則可(ke)(ke)能(neng)導致(zhi)在移(yi)動過(guo)程(cheng)中(zhong)microled等器件從transfer上(shang)脫落,而為了提高transfer過(guo)程(cheng)中(zhong)的(de)(de)穩定(ding)性,則又可(ke)(ke)能(neng)犧牲transfer的(de)(de)速度(du)繼(ji)而影響產(chan)能(neng)。

請參閱圖(tu)1,本發明提供一種微轉印方法,包括(kuo)如(ru)下步驟:
步(bu)驟s1、如圖2-3所(suo)(suo)(suo)示,提供傳(chuan)送(song)頭50、及載(zai)(zai)(zai)體(ti)基(ji)板(ban)10,所(suo)(suo)(suo)述(shu)(shu)(shu)傳(chuan)送(song)頭50具有(you)(you)數個(ge)(ge)拾(shi)取凸(tu)起(qi)51,每一拾(shi)取凸(tu)起(qi)51均具有(you)(you)吸附(fu)面511,所(suo)(suo)(suo)述(shu)(shu)(shu)載(zai)(zai)(zai)體(ti)基(ji)板(ban)10上設有(you)(you)數個(ge)(ge)微部件40,將所(suo)(suo)(suo)述(shu)(shu)(shu)傳(chuan)送(song)頭50放(fang)置于所(suo)(suo)(suo)述(shu)(shu)(shu)載(zai)(zai)(zai)體(ti)基(ji)板(ban)10上,此時(shi)所(suo)(suo)(suo)述(shu)(shu)(shu)拾(shi)取凸(tu)起(qi)51的吸附(fu)面511朝(chao)向下(xia)方,使得(de)所(suo)(suo)(suo)述(shu)(shu)(shu)拾(shi)取凸(tu)起(qi)51的吸附(fu)面511與載(zai)(zai)(zai)體(ti)基(ji)板(ban)10上的微部件40相接觸(chu),即利用所(suo)(suo)(suo)述(shu)(shu)(shu)傳(chuan)送(song)頭50的拾(shi)取凸(tu)起(qi)51吸附(fu)載(zai)(zai)(zai)體(ti)基(ji)板(ban)10上的微部件40。
步(bu)驟s2、如圖4-6所(suo)(suo)示(shi),將傳送(song)(song)頭50與載體(ti)(ti)基板(ban)10上(shang)下翻轉,此時所(suo)(suo)述(shu)(shu)傳送(song)(song)頭50位于所(suo)(suo)述(shu)(shu)載體(ti)(ti)基板(ban)10的下方,所(suo)(suo)述(shu)(shu)拾(shi)取凸(tu)起51的吸附面(mian)511朝向上(shang)方,然后(hou)將傳送(song)(song)頭50與載體(ti)(ti)基板(ban)10分離(li),此時所(suo)(suo)述(shu)(shu)傳送(song)(song)頭50承載著所(suo)(suo)述(shu)(shu)步(bu)驟s1中被拾(shi)取凸(tu)起51吸附的微部件40。
步驟s3、如圖7-9所(suo)(suo)示,提供(gong)接受(shou)基板20,將承載有微部(bu)件(jian)40的傳(chuan)送(song)頭50轉(zhuan)移到所(suo)(suo)述(shu)接受(shou)基板20的上(shang)方,然(ran)后(hou)將傳(chuan)送(song)頭50上(shang)下翻轉(zhuan),此時所(suo)(suo)述(shu)傳(chuan)送(song)頭50位于(yu)所(suo)(suo)述(shu)接受(shou)基板20的上(shang)方,所(suo)(suo)述(shu)拾取凸(tu)起(qi)51的吸(xi)附(fu)面511朝向下方,將拾取凸(tu)起(qi)51吸(xi)附(fu)的微部(bu)件(jian)40置于(yu)接受(shou)基板20上(shang)。
本發(fa)明(ming)的(de)微轉印方法,在傳(chuan)(chuan)送頭50轉移(yi)微部件40的(de)過(guo)程中(zhong),微部件40承載于傳(chuan)(chuan)送頭50上,相對于現(xian)有技術,傳(chuan)(chuan)送頭50對微部件40的(de)吸附不再需要克服重力的(de)影(ying)響,繼(ji)而在步驟(zou)s3中(zhong),在保證傳(chuan)(chuan)送頭50對微部件40穩(wen)定轉移(yi)的(de)情況下,可(ke)以對傳(chuan)(chuan)送頭50進行快速移(yi)動,有效(xiao)提高(gao)了傳(chuan)(chuan)送頭50的(de)轉移(yi)良率(lv)和速率(lv)。
具體地,每一拾取凸起(qi)51的(de)(de)吸附面511的(de)(de)尺寸(cun)均大(da)于其所吸附的(de)(de)微部件(jian)(jian)40的(de)(de)尺寸(cun),如圖10所示,所述步驟s1中(zhong)(zhong)提供(gong)的(de)(de)傳送(song)頭50中(zhong)(zhong),每一拾取凸起(qi)51的(de)(de)吸附面511的(de)(de)邊(bian)緣上(shang)(shang)均設有擋墻512,從而在傳送(song)頭50對微部件(jian)(jian)40轉移過(guo)程中(zhong)(zhong),即使微部件(jian)(jian)40發生偶爾的(de)(de)晃動(dong),由于擋墻512的(de)(de)阻(zu)擋作用,微部件(jian)(jian)40也不會從拾取凸起(qi)51上(shang)(shang)脫落。
進一(yi)步地,每一(yi)拾(shi)取(qu)凸(tu)起51上的(de)擋墻512可設(she)(she)于(yu)相(xiang)(xiang)應(ying)吸(xi)附(fu)面511四(si)側(ce)邊中的(de)某(mou)一(yi)邊上、某(mou)兩(liang)邊上、某(mou)三(san)邊上、或是四(si)周側(ce)邊上;例如(ru),如(ru)圖(tu)12所示,每一(yi)拾(shi)取(qu)凸(tu)起51上的(de)擋墻512設(she)(she)于(yu)相(xiang)(xiang)應(ying)吸(xi)附(fu)面511的(de)相(xiang)(xiang)對兩(liang)側(ce)邊上;又(you)例如(ru),如(ru)圖(tu)13所示,每一(yi)拾(shi)取(qu)凸(tu)起51上的(de)擋墻512設(she)(she)于(yu)相(xiang)(xiang)應(ying)吸(xi)附(fu)面511的(de)四(si)周側(ce)邊上,從而形(xing)成(cheng)可包圍微(wei)部件40的(de)結構(gou)。
具(ju)體(ti)地(di),所(suo)述傳送(song)頭(tou)50上的擋墻512通(tong)過光刻制(zhi)程在傳送(song)頭(tou)50成型過程中制(zhi)作形成。
具體地,如圖11所示,所述步(bu)驟s2中(zhong),每一拾取(qu)(qu)凸起(qi)51上(shang)(shang)吸附的微部(bu)(bu)件40的高(gao)(gao)度(du)均大于該拾取(qu)(qu)凸起(qi)51上(shang)(shang)擋(dang)墻512的高(gao)(gao)度(du);從而(er)在(zai)所述步(bu)驟s3中(zhong),將(jiang)傳(chuan)送頭50上(shang)(shang)下翻轉后(hou),擋(dang)墻512不會阻礙(ai)微部(bu)(bu)件40放置在(zai)接受(shou)基(ji)(ji)板(ban)20上(shang)(shang),進而(er)避免(mian)影響微部(bu)(bu)件40與接受(shou)基(ji)(ji)板(ban)20的綁定(bonding)。
具體地,所(suo)(suo)述微部(bu)(bu)件(jian)40為微發光(guang)二極管,具有金屬電(dian)極41,所(suo)(suo)述步驟(zou)s3中提供(gong)的接(jie)受基(ji)板20為tft陣列基(ji)板。進一(yi)步地,所(suo)(suo)述步驟(zou)s3還包(bao)括將微部(bu)(bu)件(jian)40的金屬電(dian)極41與接(jie)受基(ji)板20導(dao)通(tong),并(bing)使得所(suo)(suo)述微部(bu)(bu)件(jian)40固定(ding)于所(suo)(suo)述接(jie)受基(ji)板20上,即(ji)將微部(bu)(bu)件(jian)40也即(ji)微發光(guang)二極管與接(jie)受基(ji)板20進行綁定(ding)。
除此(ci)之外,所(suo)述微(wei)部件40也可以為(wei)其(qi)他微(wei)米尺寸或更小尺寸的器件,例如微(wei)集成電路(lu)芯片。
具(ju)體地(di),所述傳送頭50為pdms傳送頭,所述拾(shi)取凸起51為pdms材料,所述步驟s1中(zhong)通(tong)過拾(shi)取凸起51的(de)粘性吸(xi)附微部件(jian)40。除此(ci)之外(wai),所述傳送頭50還可以為其他類型(xing)的(de)傳送頭,比如(ru)通(tong)過靜電力來進(jin)行拾(shi)取的(de)傳送頭。
