Title: Verifying method of design parameter of semiconductor and manufacturing method of semiconductor device
Inventor: TAKASHINO HIROYUKI
IPC: G06F17/50
Filed: 2000-07-21
Abstract: PROBLEM TO BE SOLVED: To easily verify a parameter for LPE to a transistor grasping a shape when the circuit simulation of a semiconductor is carried out. SOLUTION: TCAD is carried out in a step 51 to prepare a database 52. A net list produced in a step 44 by using the database 52 is verified in a step 53. For instance, TCAD sets a parameter for TCAD so that an electric characteristic is obtained for the transistor 10. By the verification in a step 53, for instance, if drain current obtained from the transistor of the net list produced in a step 44 is matched to the result of the database 52 in a prescribed range, it is advanced to a step 45, and the circuit simulation is carried out. But if they are not matched, a parameter 46 for LPE is renewed.

Title: Safe syringe having needle cylinder
Inventor: KO GOJUN
IPC: A61M5/31
Filed: 2000-07-24
Abstract: PROBLEM TO BE SOLVED: To enhance safety of a safe syringe. SOLUTION: A needle cylinder of the safe syringe has a hub and a barrel contacted with the hub capable of being sterilized together with the syringe in a non-connected state. Thus, a stress and a thermal deformation are generated at the safe syringe to stabilize the hub and the barrel of the syringe after the sterilization to prevent a disadvantageous influence to their hermetically sealed connection. The cylinder rigidly holds a cap, the hub and the barrel of the syringe together, isolates a cannula and the hub from an external field and protects against a contamination by external contact with the cannula before using the syringe for its injection. The hub is provided to enable an easily holding of the hub by the barrel of the syringe only by pressing down the cap.  Two stoppers contacted with a rear end of the cap are provided at an inner wall of the cylinder to prevent the connection of the hub to the barrel before using for the injection by undesired pressing down of the cap.
