摘要:
In a semiconductor device of the LOC (lead on chip) structure type according to the present invention, one ends of external connector leads are fixed to an insulating tape and the other ends thereof extend outside the insulating tape. Inner leads for internal wiring are arranged and fixed on the insulating tape, independently of the others. The insulating tape integral to both of these leads is fixed to the main surface of a semiconductor chip and the leads are connected to their corresponding electrode pads on the semiconductor chip via bonding wires. The insulating tape is bonded to a lead frame before the punching process and it thus made integral to the leads is then punched by the punching process. It therefore needs no bonding margin for the leads.

摘要:
A desired isomer is selectively prepared by phosphorolyzing and isomerizing an anomer mixture of a 1-phosphorylated saccharide derivative while crystallizing one of the isomers to displace the equilibrium. Furthermore, using the action of a nucleoside phosphorylase, a nucleoside is prepared from the 1-phosphorylated saccharide derivative obtained and a base with improved stereoselectivity and a higher yield. This process is an anomer-selective process for preparing a 1-phosphorylated saccharide derivative and a nucleoside.
