Description

晶圓結構
本案關於一種晶圓結構,尤指以半導體製程製出適用於噴墨列印之噴墨晶片之晶圓結構。
目前市面上常見的印表機除雷射印表機外,噴墨印表機是另一種被廣泛使用的機種,其具有價格低廉、操作容易以及低噪音等優點,且可列印於如紙張、相片紙等多種噴墨媒體。而噴墨印表機之列印品質主要取決於墨水匣的設計等因素,尤其以噴墨晶片釋出墨滴至噴墨媒體之設計為墨水匣設計的重要考量因素。
又在噴墨晶片在追求更高的高解析度與更高速列印之列印品質要求下,對於競爭激烈的噴墨列印市場中,噴墨印表機的售價下降得很快速,因此搭配墨水匣之噴墨晶片之製造成本以及更高解析度與更高速列印之設計成本就會取決於市場競爭力之關鍵因素。
但,以目前噴墨列印市場中所生產噴墨晶片係由一晶圓結構以半導體製程所製出,現階段噴墨晶片生產皆以6吋以下晶圓結構所製出,又要同時追求更高的高解析度與更高速列印之列印品質要求下,相對噴墨晶片之可列印範圍(printing swath)之設計要變更大、更長,始可大幅提高列印速度,如此噴墨晶片所需求整體面積就更大,因此要在6吋以下有限面積之晶圓結構上製出需求噴墨晶片數量就會相當地受到限制,進而製造成本也無法有效地降低。
舉例說明,例如,一片6吋以下晶圓結構製出噴墨晶片之可列印範圍(printing swath)為0.56英吋(inch)大概至多切割生成334顆噴墨晶片。若在一片6吋以下晶圓結構上生成噴墨晶片之可列印範圍(printing swath)超過1英吋(inch)或者頁寬可列印範圍(printing swath)A4尺寸(8.3英吋(inch))來製出更高的高解析度與更高速列印之列印品質要求下,相對要在6吋以下有限面積之晶圓結構上製出需求噴墨晶片數量就會相當的受到限制,數量更少,在6吋以下有限面積之晶圓結構上製出需求噴墨晶片就會有浪費剩餘之空白面積,這些空百面積就會佔去整片晶圓面積的空餘率超過20%以上,相當浪費,進而製造成本也無法有效地降低。
有鑑於此,要如何符合噴墨列印市場中追求噴墨晶片之更低製造成本,以及追求更高解析度與更高速列印之列印品質,是本案最主要研發之主要課題。
本案之主要目的係提供一種晶圓結構,包含一晶片基板及複數個噴墨晶片,利用至少12英吋以上晶圓之半導體製程來製出該晶片基板,促使該晶片基板上可佈置更多需求數量之噴墨晶片,佈置需求更高解析度及更高性能之列印噴墨設計,用來因應不同的噴墨範圍,所以需要不同尺寸的噴墨晶片,以切割成需求實施應用於噴墨晶片,降低晶片對於噴墨晶片的限制,並且能夠減少晶片上未使用的區域,提升晶片的利用率,降低空餘率,降低製造成本,同時得以追求更高解析度與更高速列印之列印品質。
本案之一廣義實施態樣為提供一種晶圓結構,包含:一晶片基板,為一矽基材,以至少12英吋以上晶圓之半導體製程製出;至少一個噴墨晶片,以半導體製程製直接生成於該晶片基板上,並切割成至少一個噴墨 晶片實施應用於噴墨列印;其中,該噴墨晶片包含:複數個墨滴產生器,以半導體製程製出生成於該晶片基板上,而該噴墨晶片配置成沿縱向延伸相鄰個該墨滴產生器保持一間距之複數縱向軸列組,以及配置成沿水平延伸相鄰個該墨滴產生器保持一中心階差間距之複數水平軸行組,該中心階差間距為至少1/600英吋(inch)以下。

請參閱第1圖及第2圖所示,本案提供一種晶圓結構2,包含:一晶片基板20及複數個噴墨晶片21。其中晶片基板20為一矽基材,以至少12英吋(inch)以上晶圓之半導體製程製出。在具體實施例中,晶片基板20可以利用12英吋(inch)晶圓之半導體製程製出;或者,在另一具體實施例中,晶片基板20可以利用16英吋(inch)晶圓之半導體製程製出。
上述之複數個噴墨晶片21分別包含:複數個墨滴產生器22,以半導體製程製出生成於晶片基板20上,並切割成至少一噴墨晶片21實施應用於噴墨列印。又如第2圖所示,每一墨滴產生器22包含一熱障層221、一加熱電阻層222、一導電層223、一保護層224、一障壁層225、一供墨腔室226及一噴孔227。其中熱障層221形成於晶片基板20上,加熱電阻層222形成於熱障層221上,而導電層223及保護層224之一部分形成於加熱電阻層222上,且保護層224之其他部分形成於導電層223上,而障壁層225形成於保護層224上,以及供墨腔室226及噴孔227一體成型生成於障壁層225中,且供墨腔室226底部連通保護層224,供墨腔室226頂部連通噴孔227。亦即噴墨晶片21之墨滴產生器22是在晶片基板20上實施半導體製程所製出,以下予以說明。首先在晶片基板20上形成一層熱障層221之薄膜,之後再以濺鍍方式先後鍍上加熱電阻層222與導電層223,並以微影蝕刻之製程釐定所需尺寸,之後再以濺鍍裝置或化學氣相沉積(CVD)裝置鍍上保護層224,再以保護層224上以乾膜壓模成型出供墨腔室226,再塗佈一層乾膜壓模成型噴孔227,構成障壁層225一體成形於保護層224上,如此供墨腔室226及噴孔227一體成型生成於障壁層225 中,或者,在另一具體實施例上,係在保護層224上以高分子膜直接以微影蝕刻製程定義出供墨腔室226及噴孔227,如此供墨腔室226及噴孔227一體成型生成於障壁層225中,因此供墨腔室226底部連通保護層224,頂部連通噴孔227。其中晶片基板20為矽基材(SiO2),加熱電阻層222為鋁化鉭(TaAl)材料,導電層223為鋁(Al)材料,保護層224由在下層的第一保護層224A堆疊上層的第二保護層224B所構成,第一保護層224A為氮化矽(Si3N4)材料或碳化矽(SiC)材料,障壁層225可以為一種高分子材料。
當然,上述噴墨晶片21之墨滴產生器22在晶片基板20上實施半導體製程所製出,在以微影蝕刻之製程釐定所需尺寸過程中,如第3A圖至第3B圖所示進一步定義出至少一供墨流道23及複數個岐流道24,再以保護層224上以乾膜壓模成型出供墨腔室226,再塗佈一層乾膜壓模成型噴孔227,如此構成如第2圖所示障壁層225一體成形於保護層224上,且供墨腔室226及噴孔227一體成型生成於障壁層225中,供墨腔室226底部連通保護層224,供墨腔室226頂部連通噴孔227,噴孔227如第3D圖所示直接裸露於噴墨晶片21表面構成需求的排列佈置,因此供墨流道23及岐流道24也是同時以半導體製程製出,其中供墨流道23可以提供一墨水,而供墨流道23連通複數個岐流道24,且複數個岐流道24連通每個墨滴產生器22之供墨腔室226。又如第3B圖所示加熱電阻層222成形裸露於供墨腔室226中,加熱電阻層222為具有一長度HL及一寬度HW所構成一矩形面積。
又請參閱第3A圖及第3C圖所示,供墨流道23為至少1個至6個。第3A圖所示單一噴墨晶片21之供墨流道23為1個,可以提供單色墨水,此單色墨水可以分別青色(C:Cyan)、洋紅色(M:Megenta)、黃色(Y:Yellow)、 黑色(K:Black)墨水。如第3C圖所示單一噴墨晶片21之供墨流道23為6個,分別提供黑色(K:Black)、青色(C:Cyan)、洋紅色(M:Megenta)、黃色(Y:Yellow)、淺青色(LC:Light Cyan)和淡洋紅色(LM:Light Megenta)六色墨水。當然,在另外實施例中,單一噴墨晶片21之供墨流道23也可為4個,分別提供青色(C:Cyan)、洋紅色(M:Megenta)、黃色(Y:Yellow)、黑色(K:Black)四色墨水。供墨流道23數量可依實際需求設計來佈置。
再請參閱第3A圖、第3C圖及第4圖所示,上述導電層223係以在晶圓結構2上實施半導體製程所製出,其中導電層223所連接之導體可以至少90奈米以下之半導體製程製出形成一噴墨控制電路,如此在噴墨控制電路區25可以佈置更多金屬氧化物半導體場效電晶體(MOSFET)去控制加熱電阻層222形成回路而激發加熱或未形成回路則不激發加熱;亦即如第4圖所示加熱電阻層222受到一施加電壓Vp時,電晶體開關Q控制加熱電阻層222接地之回路狀態,當加熱電阻層222之一端接地形成回路而激發加熱,或不接地不激發加熱,其中電晶體開關Q為一金屬氧化物半導體場效電晶體(MOSFET),而導電層223所連接之導體為金屬氧化物半導體場效電晶體(MOSFET)之閘極G;在其他較佳實施例中,導電層223所連接之導體為也可為一互補式金屬氧化物半導體(CMOS)之閘極G,或者導電層223所連接之導體可為一N型金屬氧化物半導體(NMOS)之閘極G。導電層223所連接之導體可依實際噴墨控制電路之需求去搭配選擇適當電晶體開關Q。當然,導電層223所連接之導體可以90~65奈米半導體製程製出形成一噴墨控制電路;導電層223所連接之導體可以65~45奈米半導體製程製出形成一噴墨控制電路;導電層223所連接之導體可以45~28奈米半導體製程製出形成一噴墨控制電路;導電層223所連接之導體可以28~20奈米 半導體製程製出形成一噴墨控制電路;導電層223所連接之導體可以20~12奈米半導體製程製出形成一噴墨控制電路;導電層223所連接之導體可以12~7奈米半導體製程製出形成一噴墨控制電路;導電層223所連接之導體可以7~2奈米半導體製程製出形成一噴墨控制電路。可以理解的是,以越精密的半導體製程技術,其在相同的單位體積下可以製出更多組的噴墨控制電路。
