摘要:
A piezoelectric material layer is easily formed on a partial region of the substrate surface. By forming a different hardness material layer that has a different hardness from that of the substrate in the form of a pattern on the surface of the substrate, a film-deposition permitting region A to which particles of a piezoelectric material in a carrier gas adhere in a form of a film and a film-deposition inhibiting region B which inhibits the formation of a film are provided. Further, when a carrier gas containing particles of a piezoelectric material are ejected onto the surface of the substrate by means of AD, a film-like piezoelectric material layer is formed as a result of the adhesion of the particles in the film-deposition permitting region A. As a result, the piezoelectric material layer can be formed easily in a partial region of the surface of the substrate.

A semiconductor chip mounted interposer (60) is configured by executing wire bonding between a semiconductor chip (50) and an interposer (20), in which terminals (21) that connect to terminals (51) of the chip (50) and separate terminals (22) are formed, on the upper face of the interposer (20). A semiconductor chip (30) is mounted to the top face of a package substrate (10), the interposer (60) is adhered to the upper portion of the chip (30), and wire bonding is executed between the terminals (22) and terminals (11′). When configuring a semiconductor device with a plurality of semiconductor chips combined into one package in this manner, KGD (Known-Good-Die) can easily be guaranteed for each semiconductor chip, and semiconductor devices can be fabricated with a high yield of good units. Also, the semiconductor chips can be used as-is, without restricting the position, pitch, signal arrangement, or the like, of their terminals.

摘要:
Ultra-fine particles are jetted from a nozzle to be deposited on a substrate via a mask which is plate-shaped and in which an opening pattern is formed, thereby forming on the substrate a thin film having a shape corresponding to the opening pattern. The mask has a first area, a second area which surrounds the first area and defines an opening between the first area and the second area, and a bridge portion connecting the first and second areas. The bridge portion is formed at a position away from the bottom surface of the mask. By using this mask, a thin film having a pattern including an independent non-film formation area can be formed.
