Title: Processing method for metallic film in semiconductor element
Inventor: UCHIDA MASAO
IPC: H01L21/338
Filed: 1981-04-06
Abstract: PURPOSE:To prevent re-adhesion in case of ion milling without adding a new process by adjusting the film thickness of an adhering metal and exerting a shielding effect by utilizing the shape of the metal. CONSTITUTION:A resist 2 with a thickness and b opening size is formed onto a semiconductor substrate 1. When metallic particles are advanced rectilinearly at an incident angle theta1 from the A direction and evaporated 3 and there are points P, Q, R on one straight line, film thickness h=a<2>/bXtan theta1 is formed. When ion milling is conducted at an angle theta2 from the B direction under this condition, the metallic particles dispersed from the metal 3 adhering on the side wall of the resit 2 are interrupted by the point Q, and do not adhere on the exposed section of the substrate 1 again. When film thickness h>a<2>/bXtan theta1 is selected, a metallic pattern 16' with sub-micron size can be formed by a simple process through normal photoengraving technique by self-matching without the additional process.

Title: Detecting method for semiconductor chip
Inventor: TSUKISHIRO SHIZUO
IPC: H01L21/66
Filed: 1985-03-14
Abstract: PURPOSE:To detect the presence or absence of a semiconductor chip by detecting the prescribed potential given through a detecting pad to a chip detecting needle in case of contacting the needle with the pad formed at the prescribed position on the chip. CONSTITUTION:A probing needle 3 is contacted with a device electrode pad 2 in case of measuring, and a detecting needle 8 is contacted with a detecting pad 7 provided similarly at the pad 2 at the periphery of a chip 1. If the chip is presented, a state 5 is raised, and the needle 8 is contacted with the pad 7. When contacting, the state 5 is conducted through a wafer 10 and an N<+> type layer 9 with an aluminum for forming the pad 7. Accordingly, a detection signal (a) becomes substantially the potential of the stage 5, i.e., 0 volt. This is because the resistance value (r) of a series resistor 11 formed of the wafer 10 and the layer 9 from the stage is sufficiently smaller than the resistance value R of a detecting electrode pullup resistor 6.

Abstract: PURPOSE:To perform excellent broadcast receiving operation by continuing noise suppressing operation by generating a detection pulse when the width of a retangular pulse waveform-shaped by a Schmitt trigger circuit exceeds a reference value set in a pulse width detecting circuit in case of a low vehicle speed. CONSTITUTION:While the vehicle is running at a high speed, the output of Schmitt trigger circuit 9 is applied as it is to high-cut control circuit 13 and high-blend control circuit 15 via OR gate 12.
