Description
本発明の実施形態に係るデバイスウェーハ10の加工方法について、図面に基づいて説明する。まず、実施形態の加工対象を含むフレームユニット1の構成について説明する。図1は、実施形態にかかるデバイスウェーハ10の加工方法の加工対象を含むフレームユニット1の一例を示す斜視図である。
図3は、図2に示すマスク被覆ステップ1001の一例を一部断面で示す側面図である。マスク被覆ステップ1001は、デバイスウェーハ10の表面12に水溶性樹脂105を保護マスク20として被覆するステップである。
図4は、図2に示すマスク形成ステップ1002の一例を一部断面で示す側面図である。図5は、図4のデバイスウェーハ10の要部の断面図である。図6は、図4のマスク形成ステップ1002後の一状態を示すデバイスウェーハ10の要部の断面図である。マスク形成ステップ1002は、マスク被覆ステップ1001の実施後に実施される。マスク形成ステップ1002は、レーザー光線205をデバイスウェーハ10の表面12の分割予定ライン13に沿って照射して保護マスク20及び機能層15を除去するとともにレーザー加工溝22を形成して基板11を露出させるステップである。
図7は、図2に示すプラズマエッチングステップ1003の一例を示すデバイスウェーハ10の要部の断面図である。図8は、図7のプラズマエッチングステップ1003後の一状態を示すデバイスウェーハ10の要部の断面図である。プラズマエッチングステップ1003は、マスク形成ステップ1002の実施後に実施される。プラズマエッチングステップ1003は、デバイスウェーハ10の表面12にプラズマ状態のガス300を供給し、レーザー加工溝22に沿って基板11を分割する分割溝24を形成するステップである。
図9は、図2に示す拡張ステップ1004の一状態を一部断面で示す側面図である。図10は、図2に示す拡張ステップ1004の図9の後の一状態を一部断面で示す側面図である。図11は、図10のデバイスウェーハ10の要部の断面図である。図12は、図2に示す拡張ステップ1004の図10の後の一状態を一部断面で示す側面図である。拡張ステップ1004は、プラズマエッチングステップ1003の実施後に実施される。拡張ステップ1004は、保護テープ50を面方向に拡張し、分割溝24の幅を拡張するステップである。
図13は、図2に示す追加塗布ステップ1005の一例を一部断面で示す側面図である。図14は、図13の追加塗布ステップ1005後の一状態を示すデバイスウェーハ10の要部の断面図である。追加塗布ステップ1005は、実施形態では拡張ステップ1004の実施後に実施されるが、本発明ではプラズマエッチングステップ1003の実施後、かつ接着フィルム分割ステップ1006の実施前であれば、いずれのタイミングで実施されてもよい。追加塗布ステップ1005は、水溶性樹脂105を分割溝24が形成されたデバイスウェーハ10に塗布するステップである。
図15は、図2に示す接着フィルム分割ステップ1006の一例を一部断面で示す側面図である。図16は、図15のデバイスウェーハ10の要部の断面図である。図17は、図15の接着フィルム分割ステップ1006後の一状態を示すデバイスウェーハ10の要部の断面図である。接着フィルム分割ステップ1006は、実施形態では追加塗布ステップ1005の実施後に実施されるが、本発明では追加塗布ステップ1005を省略して拡張ステップ1004実施後に実施されてもよい。接着フィルム分割ステップ1006は、分割溝24を介して露出した接着フィルム30にレーザー光線205を照射し、分割溝24に沿って接着フィルム30を分割するステップである。
図18は、図2に示す洗浄ステップ1007の一例を一部断面で示す側面図。図19は、図18の洗浄ステップ1007後の一状態を示すデバイスウェーハ10の要部の断面図である。洗浄ステップ1007は、接着フィルム分割ステップ1006の実施後に実施される。洗浄ステップ1007は、水溶性樹脂105による保護マスク20を洗浄することによって除去するステップである。
