Title: Forming method of inorganic resist film
Inventor: FUJITA JUNICHI
IPC: G03F7/26
Filed: 1994-06-27
Abstract: PURPOSE:To form a pattern in a nanometer size by using an inorg. resist. CONSTITUTION:A calixarene film 2 is formed on a silicon substrate 1, on which an inorg. resist 3 prepared by adding aluminum fluoride to lithium fluoride is formed and exposed to electron beams. Since the resist 3 is formed on the calixarene film 2, growth of islands during the initial stage of growing the resist film and the reaction with the substrate are prevented, as a result, the resist is made of extremely fine particles. The average particle size of the particles is about 3nm. In the resist, a pattern of lines and spaces with 60nm pitch and 5nm line width can be drawn by exposure with EB. When the substrate temp. is decreased to -70 deg.C during growing the resist film, the particle size can be decreased to <=3nm and a more precise pattern can be formed. Further, when it is necessary to form the substrate org. film to have certain thickness such as a suspended mask, the deformation of the base film can be prevented by irradiating the base film with electron beams.

Abstract: PURPOSE:To enhance heat dissipation properties of semiconductor device by providing protrusions and recesses on the surface of a package, fitting a heat dissipation fin thereto, thereby increasing the contact surface area between the package and the fin and the quantity of heat being conducted from the package to the fin. CONSTITUTION:A heat dissipation fin 7 is fitted through protrusions and recesses to the surface of a package 6. Consequently, contact area is increased between the package 6 and the fin 7 thus increasing the quantity of heat being transmitted from the package 6 to the fin 7. As a result, heat dissipation properties of semiconductor device are enhanced and a high integration semiconductor device can be operated stably with high reliability. Furthermore, no gap is produced between the package 6 and the fin 7 because the package 6 is bonded to the fin 7 through a bonding material 8. This structure transmits heat positively from the semiconductor to the fin 7 thus realizing positive heat dissipation of the semiconductor device.
