Title: Clock compensation device for semiconductor device
Inventor: CHOI JAE MYOUNG
IPC: H03K5/13
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To shorten the locking time and to secure an expanded frequency range by outputting a pump potential to perform the control so as to keep the phase difference within a range of delay of delay elements between the external and internal clocks if the phase difference gets out of the range of delay. SOLUTION: When the delay time is set at 2ns, for example, the delay times of outputs OUT0 to OUT3 of the 1st to 4th delay elements are set at 2ns, 4ns, 6ns and 8ns respectively. Then an external clock is inputted to a multiplexer as soon as it's inputted to a delay element. If the phase difference is set at 4ns between the external clock and an internal clock that is first outputted, the output OUT1 is selected via the multiplexer to delay the internal clock by 4ns. However, if the phase difference is smaller than 2ns or larger than 8ns between the internal and external clocks, a charge pump raises or drops its potential Vpump to totally control a range of delay.

Title: Substrate treatment device
Inventor: UCHIYAMA SHIGEYA
IPC: H01L21/677
Filed: 1991-12-26
Abstract: PURPOSE:To prevent a treated substrate from being contaminated by a contaminant attaching to an untreated substrate by providing a substrate holding device of a substrate transfer device with a holding part for an untreated substrate and a treated substrate. CONSTITUTION:A substrate transfer device 3 transfers a substrate from a carrier C wherein a plurality of substrates are contained to a substrate carrying robot 6. In the process, an untreated substrate is held by a groove 45a of a holding part 45 of a substrate holding device 16. Thereafter, the substrate is carried to a treatment bath 4 by the substrate carrying robot 6 and a surface treatment is carried out in the treatment bath 4. After the treatment, the substrate carrying robot 6 carries the treated substrate from the treatment bath 4 to the substrate transfer device 3. The substrate transfer device 3 receives the treated substrate and holds it by the groove 46a of the holding part 46. Since an untreated substrate is held by the holding part 45 and a treated substrate is held by the holding part 46 in this way, a contaminant attaching to untreated substrate does not attach to a treated substrate through a holding part, thereby preventing contamination of a treated substrate.
