고조파영상을생성할수 있는초음파진단장치및 고조파영상을포함하는초음파영상생성방법이개시된다. 개시된초음파진단장치는기본주파수성분과적어도하나의고조파성분을동시에갖는초음파신호를피검체에송신하기때문에, 피검체에서반사되어수신되는초음파에코신호내의고조파성분의크기를증가시킬수 있다. 따라서, 고조파영상의품질을향상시킬수 있다.
Abstract:
PURPOSE: A substrate level bonding method and a substrate level package are provided to apply superior bonding force regardless of the surface shape of a substrate by adopting a dry-film resist(DFR) as an adhesive material. CONSTITUTION: A first substrate including a plurality of substrate units is prepared(S10). The substrate units are spaced apart by holes. A first DFR layer is formed on the first surface of the first substrate(S20). Substrate adhered parts of the first DFR layer which covers each substrate unit is partially hardened(S30). Parts of the first DFR layer which corresponds to the holes are removed(S40). The external surface of the substrate adhered parts are attached to a second substrate(S50).
